Can’t Ride 55 – 2000 Ducati 996 SPS

Though you would had to have been a racer or one of your Ducati dealer’s best customers to rate a 996 SPS back in 2000, they are starting to appear with some regularity.  Most have just introductory miles like this one, and are carefully tended.

2000 Ducati 996 SPS #1214 for sale on eBay

Ducati and Carl Fogarty were working hard to continue their championship-winning ways, and the SPS was their homologation special for the turn of the century.  Not radically different than a base 996, it’s just a little more powerful with 123 hp.  Suspension was top-of-the-line Öhlins for 2000, and worked well with the adjustable frame geometry to suit a rider’s preference.  Marchesini forged their 17-inch wheels for the occasion, and likewise Brembo supplied their best 4-piston calipers up front.  A sea of racing red gives way to white number areas behind the single seat.

For whatever reason this short-term owner didn’t warm up to the red experience, fortunately the previous completed a major service last summer.  Miles are not significant at 4,565, and it looks very stock, right down to the clutch cover.  Condition looks great save one near miss on the right seat console, and the belt buckle / key guard is cheap insurance.  Some SPS’s come with their original tires, but thankfully this one has new rubber.  The owner’s comments from the eBay auction:

The bike is all original, it’s been ridden and well cared for. 

-4570 miles with almost new tires (under 400 miles)

-went through a thorough inspection in September 2019 (when purchased). All fluids and fuel system were flushed and replaced. Switched water tank to carbon fiber one. 

-battery, spark plug, belts were serviced July 2019

Foggy’s 2000 season ended early in a collision at Philip Island, but the work he did developing the 996 paid off with Troy Corser’s 2001 championship.  Though the 996 could be a chore around town, as speeds exceed highway normality and the wind lightens the load on the rider’s wrists ( and makes the cooling system work ), it turns into a great pleasure.  Maybe the next owner will take the new tires at their word and put a few miles on this millennial beauty.

More Than Skin Deep: 1998 Ducati 916 SPS for Sale

We’ve been a little Ducati-heavy this week, but there’s no way I was going to skip this one: an Eraldo Ferracci-prepped and tuned Ducati 916 SPS. Sure, this might look like yet another boring 916, but the SPS is one of Ducati’s fire-breathing homologation specials, and this example has been endowed with a highly-tuned stroker motor from one of the era’s premier tuners.

If you’re not familiar with Ferracci, he was an east coast Ducati tuner whose bikes won several World Superbike and AMA titles. He eventually opened a well known Ducati/MV Agusta dealership, and the company still sells high-performance Ducati parts on their site, although the brick-and-mortar dealership itself is closed.

The SPS or “Sport Production Special” was basically a way for Ducati to begin racing their stronger, larger-displacement 996cc v-twin before the 996 was introduced. As with all the bikes in the 916/996/998 series, it might look like a regular 916, but featured extensive, evolutionary upgrades to the Tamburini superbike that was introduced way back in 1994. It used the close-ratio box from the smaller 748, along with updated suspension that included an Öhlins shock and a lighter frame.

But of course, the heart of the matter was the updated 996cc engine that included titanium connecting rods for 1998. Ducati found that the functional limit for their original Desmoquattro was 955cc: any bigger, and the cases tended to crack under racing stress. The new engine was a comprehensive redesign that saw the inclusion of new heads, barrels, pistons, injectors, and a lighter crank.

Combined with the usual tuning tricks that didn’t make it over to the regular 996, the changes all added up to an engine that was more than the sum of its parts, with a savage and aggressive character. It was very expensive, but made testers at the time struggle to find enough superlatives to adequately describe the lust it inspired. The seller borrows a good chunk of his description from a very nice history of the SP/SPS Ducatis over at OddBike, and it’s worth a read if you’ve never checked that site out.

From the original eBay listing: 1998 Ducati 916 SPS for Sale

About This Motorcycle:

“The primary reason of building the 916 SPS was to homologate the new 996cc engine for Superbike competition but fortunately for bike fans, the installation of the 996 engine into the 916 setup produced a bike that was described as legendary, astonishingly good looking and a true Superbike. Only 404 examples were built with less than 50 of those imported into the States.

The SPS was released to homologate the new 996cc engine for Superbike competition. The previous 916 crankcases had been maxed out at 955cc, and had problems with cracking and stress fractures under racing conditions. So in 1997 Ducati tried again by taking their new 996 engine and putting it into the 916 frame. The result was the 916 Sport Production Special (SPS).

New reinforced crankcases were needed, and to accommodate a displacement closer to the 1000cc limit for twins in Superbike the case mouths needed wider openings and wider stud spacing to match. Thus the barrels and heads were new, made wider to match the new cylinder stud spacing. Bore was now up to 98mm, with the same 66mm stroke as before. The heads had larger combustion chambers and bigger valves. Compression ratio was now 11.5:1 inside a lighter crankshaft with tungsten plug balancing. The high pressure double injector fuel setup with P8 ECU was carried over from the SP.

Press reviews of the 996 powered SPS declared it to be something quite special, with some testers being able to crack 170 miles per hour with the Termignoni exhaust and ECU kit fitted, a pretty stunning speed for a twin with ‘only’ 120-odd horsepower. The new engine gave a much wider power delivery band but this together with neck-snapping torque was enough to push the limits of the chassis. The 916 models in general did not respond well to ham-fisted riders, so it is not surprising that the SPS and its significantly wider power band resulted in a bike that could be dangerous for even skilled riders.

Despite its somewhat dangerous reputation the SPS was still sexy as hell with a sound like the apocalypse, especially if the Termi pipes were installed. Price tag new was almost $25,000 USD, a significant amount above the $16,500 Biposto and nearly double the price of a 748 model. Most reviewers declared that despite its dangerous nature it was worth the extra investment and there was a lot of demand for the SPS but since these bikes were built for homolgation, just 404 examples were built and only a small number of those brought into the USA.”

Among these rare breed of motorcycles there is something even more special and quite possibly one of the most spectacular, modern era homologated Ducatis. Now that would be tough to believe except this is a FBF bike, but for those who know about Eraldo Ferracci and his relationship with Ducati will easily justify the aforementioned statement.

Speedart Motorsports acquired this motorbike few years back and it has been a highlight of our Ducati collection ever since.

The first owner of this stunning example took delivery in November 1998 from Mr. Ferracci and he commissioned FBF on November, 11 to transform the SPS in to one of their 1,026 cc stroker fire-breathing monsters at an exorbitant cost.

The following is a partial list of the work performed by Eraldo Ferracci with an FBF serial number stamped on the case, further attesting to the pedigree of this extravagant Production Special.

  • Renthal quick change rear sprockets carrier
  • Ferracci billet lightweight flywheel
  • High pressure fuel regulator
  • Ported and polished heads
  • Stage-3 Eprom chip
  • Corse rearsets
  • 37mm Intake valves
  • 31mm Exhaust valves
  • 54mm Ferracci Forza full stainless system
  • Ohlins shock revalved
  • Hyperpro spring
  • Ferracci billet clip-on handlebars
  • 98mm 12:1 Compression piston Kit
  • FBF power crank 68mm stroke
  • Ducati Performance carbon fiber under-seat oil vent tank
  • MS Production carbon air intake runners
  • Stage-3 cams
  • Pankl Racing titanium rods
  • Carbon fiber MS Production swingarm cover

During our custodianship at Speedart Motorsports, further enhancements were performed including Dymag carbon fiber wheels, ultra-rare Ducati Corse RS slipper clutch with DP carbon cover, NCR sprocket carriers, Poggipolini titanium fasteners, Samco hoses, Spiegler cables with fittings and much more.

The sale of this legendary Ducati is accompanied by extensive documentation, owner’s manuals, all Ferracci build records including Dyno sheets, fastidious maintenance receipts, stands, cover, etc.

Speedart Motorsports invites all serious inquiries of what is believed to be the most extraordinary 916 Sport Production Special in captivity, freshly serviced, in spectacular form both cosmetically and mechanically.

The high-compression pistons match the original 98mm bore, but the new crank’s 68mm stroke is up 2mm from the original for a total of 1026cc, compared to the original 996. That might bother some collectors, but it looks like only the very best parts have been used to upgrade and tune this very special SPS. Other than the gold plugs that don’t match the frame paint, this is a very nice, very trick bike, and one of just 1058 built in 1998. A nice SPS will generally sell for much less than the $34,500 asking price seen here, but they usually haven’t had as much attention lavished on them.

Touchstone – 1995 Ducati 900 SS/SP

In a rare marketing maneuver, Ducati brought the 900 SS/SP to our shores only, a limited edition with adjustable suspension and carbon eye candy.  This example has been been maintained internally and externally, and looks ready to rumble.

1995 Ducati 900 SS/SP #412 for sale on eBay

The trellis frame which was light and economical to manufacture back then is now a classic Ducati feature, in some years gold or white, but silver for 1995 which goes well with the SP’s aluminum swingarm.  Ditto the air-cooled desmodue, a good air-cooled performer with 84 carbureted ponies, and though the future brought fuel injection and dual plugs, it’s a classically flexible powerplant.  Showa suspension was the big upgrade for the SP, along with carbon mudguards.  The cockpit has occasionally been described as “everything you need, and nothing you don’t”, and it’s the perfect layout for an afternoon on the back roads.

Seeming to be in much better shape than nearly 33K miles would allow, I’d presume a refinishing if not restoration.  The pictures are not super high fidelity, but show no apparent trauma.  A lot of carefully chosen niceties such as factory open airbox, Remus carbon mufflers, new lithium-iron battery – even new footpeg and shift rubbers !  Heads and cylinders were overhauled a few years back making this SP more ready for the long term.  Just a snippet of the comments from the eBay auction:

This motorcycle has been preserved exactly as one would want. Period. I have gone to great lengths to minimize any unnecessary changes that would otherwise compromise what Ducati intended this bike to be. Obviously a blood-red Italian work of art needs nothing in the way of cosmetics, so let well enough alone.

I felt the best use of any improvements would be more of personal expressions such as un- restricting the exhaust to allow the bike to actually sound like a Ducati should with a set of Remus canisters. These match the factory equipped carbon fiber components much better than any others in my opinion. To facilitate the most from the exhaust, I perfectly jetted the carburetors. No flat spots, nor burning eyes, and of course the results are impressive for the torque curve of an already excellent engine.

To welcome more fresh air into the carburetors, I added the Genuine Ducati air-box cover. I’m sure others with hole saws and hack-saw blades get the same results, but I chose OEM whenever possible. As far as the Slave Cylinder, the stock one seemed to lack feel and a clean return. Off it went and was promptly replaced by the excellent unit from Pro Italia. Regarding the braking system, it is what it is. Nobody was impressed when new, the same remains today. I added Ferodo pads at both ends and have felt these are aggressive enough for a spirited run through the curves.

The Supersports served as Ducati’s all-rounder before the Monster came along, and went to work, touring, and to the track without complaint.  This seminal Duc has done some miles but carefully, and been maintained as though it would be in the stable forever.  The ask for a high-mileage machine can always be debated, but at least the “make offer” button is available.

The King in Yellow: 1996 Ducati 900SS/SP for Sale

Not too many bikes look good in yellow, and that very short list is mostly made up of Italians, Ducatis in particular. Red may be the most traditional color for Ducatis but the 916, Panigale, and this 900SS/SP look so striking in the bold yellow seen here, especially with the half-fairing that reveals most of the classic, air and oil-cooled v-twin. Most of the half-faired bikes here in the US were the lower-spec CR model with much more basic suspension, but some apparently did come that way from the factory, and I’d definitely configure my dream-build SP that way. Yes, I do have a dream-build SP, and it’s basically this one, with a two-up seat.

The Supersport was a mainstay of Ducati throughout the 90s, and was available in 900, 750, and even 400cc flavors, depending on the market. Here in the US, we got the 900, although 750cc examples do show up for sale from time to time, apparently sneaking in over the border. The 900SS came in two flavors: the SS/SP and the SS/CR. The motors for both versions were in an identical, as was most of the bodywork. As mentioned earlier, bikes could be had with a full or half-fairing and the SP generally had a carbon fiber front fender for, you know, weight savings. The aluminum swingarm doesn’t look quite as trick, but probably offered a greater performance benefit.

The biggest difference was the suspension. The CR or “cafe racer” came with non-adjustable suspension, because apparently cafe racer people don’t really care about handling all that much? Anyway, the SP or “sport production” came with a fully adjustable Showa front end and shock. Parts are completely interchangeable, so some CRs have been updated, but this example does have the plaque on the top triple that indicate this is an original SP.

It’s not completely stock, with a white frame, solo tail, and graphics meant to evoke the very limited-production Superlight, along with a low-profile LED taillight instead of the chunky 90s piece, but this 900SS still has the brackets for the passenger pegs, so it would be a relatively simple thing to put it back closer to stock. The Öhlins shock is a welcome update and the bike appears to be very nicely put together, as long as you’re okay with the non-standard paint.

1996 Ducati 900 Supersport SP Half Fairing Monoposto 

I’m selling my 1996 Ducati 900 Supersport SP.
The bike was rebuilt by Johann Kaiser of Moto Motivo in Raleigh, North Carolina in 2017. 
The bike is powered by a 904cc desmodromic V-twin paired with a six-speed transmission. 
It features yellow bodywork with a white-colored trellis frame, and features include new Brembo brakes, upgraded Ohlins rear shock, cast aluminum wheels, and a carbon fiber exhaust and fenders.
The bike has a clean NC title in the seller’s name.
Has been garaged and has about 1000 miles after rebuild, and runs great.

You can find the bike on Moto Motivo’s website:
https://www.motomotivo.com/restorations

As mentioned above, I have a soft spot for these bikes. I’m a huge fan of the engine and the looks are a little bit retro and a little bit modern at the same time. It’s not really sleek, but solid and handsome, a practical sportbike that doesn’t overwhelm with power but can still handle well enough to entertain. With nice, original examples beginning to increase in value, the $6,000 asking price is a steal, if it’s anywhere near as nice as it looks in pictures. I’d look for a set of classic Termignoni cans to really finish it off and just enjoy the two-valve boom and midrange shove while bombing along a set of canyon roads.

Featured Listing – 1999 Ducati 996 SPS #481

Update 3.20.2020: This bike has SOLD! Congratulations to buyer and seller! -dc

Ducati wanted to continue their WSBK winning ways, and presented an homologation special to legalize their 996.  Just a few hundred SPS were made in any year and they appear only occasionally.  This example has been returned to riding status after a long time on display and looks excellent.

1999 Ducati 996 SPS with 4,560 Miles !

The 996 added a new desmoquattro to the legendary 916 design, the increased bore bringing 123 hp to the track-oriented machine.  Pit lane features like quick-release fairings, flip-up seat, and single sided swingarm made service items easy to get to.  SPS buyers who were going right to the track needed the adjustable steering head angle, but all appreciated the lightweight Marchesini rims, adjustable Showa forks and Öhlins monoshock and steering damper.  Monoposto seat and red paint were part of the SPS package.

Over the 20 years this SPS has travelled under 5,000 miles, and looks very original.  RSBFS reader Chris has these notes:

– only 4,560 miles on odometer
– professionally gone through / got running / checked over
– new battery, belts replaced, new fuel pump, screen, filter, air filter, spark plugs
– tank cleaned, injectors and lines cleaned, oil change
– light weight, lots of carbon fiber
– only minor blemishes from years of sitting / storage, little riding, no major damage of any kind
Asking $12,990

As the 916 – 996 – 998 family progressed up the slippery slope of track-ability, street manners suffered with ergonomics and cooling systems that called for highway speeds at minimum.  But the 996 SPS is in a good spot on the timeline, and with a little judicious route planning and maybe a fan override switch, can make for an exhilarating morning off.  The extra power and lightness reviewed as worth the upcharge when new, and look like an absolute bargain these days.

Rothmans Replica: 1991 Honda NSR250R SP for Sale

Many Japanese bikes aren’t intentionally sexy, in the way that a Bimota or MV Agusta often is, and they often fall flat stylistically when they do try to put style ahead of function. Italian machines are almost gratuitously beautiful, full of details that don’t enhance the bike’s performance, they just make the parts more interesting to look at. But Honda’s two-stroke NSR250R SP isn’t that kind of bike. Introduced in 1988, the MC18 version of the bike was motivated by a liquid-cooled, two-stroke 90° v-twin with a cassette-style six-speed gearbox, with the SP or “Sport Production” version adding a dry clutch and Magtek magnesium wheels, along with fully-adjustable suspension.

At its heart, a motorcycle is lean and elegant, and should include nothing that doesn’t absolutely need to be there. That’s especially true for a lightweight machine like Honda’s NSR250R, where every extra ounce is an enemy of speed. Instead of swoopy fairings with exposed carbon fiber details like you’d see on something else, it just has simple, elegant bodywork to enclose the hard parts, channel air to the radiator, and improve the aerodynamics.

Instead of an Aprilia’s organic, sculptural frame, it’s just a pair of extruded aluminum beams with cast sections, light and strong. A cool “gull-arm” swingarm allowed clearance on the right-hand side for the exhaust and expansion chamber to tuck in close to the bike for improved cornering clearance. And all that elegant simplicity adds up to one of the best-looking bikes of the era. It just looks right.

Of course, the “elegant simplicity” goes right out the window with the Rothmans Replica. Subtle, it isn’t, but it works, and this is one of my favorite sportbikes of any period. Obviously, I’m not alone, and the NSR250R and Rothmans Replicas in particular are highly sought after, especially clean, low-mileage examples like this one.

From the original eBay listing: 1991 Honda NSR250R SP Rothmans Replica for Sale

You are bidding on a 1991 NSR250 MC21 with the Rothmans Blue/White livery paint scheme. I purchased this motorcycle from Moto2 Imports in February of 2017 with 8,050 kilometers (5,002 miles) on the odometer. Moto2 Imports brought the NSR250 in from Japan and completely refurbished it. In the 27 months I have owned it I have only put 335 kilometers on the bike and all those miles were mainly for dialing in the correct jetting for my high-altitude riding in Colorado. The NSR250 is in perfect condition and has been stored in my heated garage along with all my other motorcycles. In addition, I installed a 3M clear bra on the upper and lower fairings. All the fluids are fresh and the battery is in great condition as it is hooked up to a trickle charger/conditioner that also desulphanates the battery. I have reluctantly come to the decision to sell my NSR250 for two main reasons, 1) My knees just can’t take the relatively cramped riding position, and 2) I have 4 other motorcycles competing for my limited riding time in the summer months and the NSR250 just won’t get ridden much and it is just doesn’t make sense to me to own a great motorcycle like the NSR250 if it is not going to be ridden as I am not one to just have a motorcycle to look pretty on stand in my garage.

Please note the NSR250 is titled in the state of Colorado and it is also currently registered in the city of Denver. It is the winning bidder’s responsibility to check with their local state, county and city of residence to ensure the NSR250 can be registered there. I will be glad to answer any questions or provide any additional photos if desired

The winning bidder is responsible for all shipping charges, but I will be glad to assist with the pick up on my end. I can recommend a couple of motorcycle transport companies I have had good service from in the past if desired.

This example is in very good condition, and has covered only 5,210 miles from new. As the seller mentions, you should check with local laws if you plan to register this for road use, as they vary pretty wildly from state-to-state. It’s good that the seller is selling because he isn’t interested in a display bike, as these machines were built to be ridden. But I think we can all agree that, if you did want a bike to adorn your garage or living room with some two-wheeled art, the Rothmans Replica would make a great candidate!

Terra Racing Replica: 1989 Honda NSR250R SP for Sale

When you mention “race replicas” the phrase tends to conjure up images of lurid colors and graphics freed from any need for subtlety or adherence to an aesthetically-pleasing color palette. Or is that just me? Maybe just me. Anyway, as much as I personally don’t tend to be a huge fan of them, there are obviously exceptions: I love the Rothmans and Repsol designs, in spite of their unsubtle styles, and MV’s Reparto Corse graphics are pretty cool as well. Of course, the vivid colors and striking graphics obviously serve an important purpose: to help draw attention to what are essentially rolling billboards for the sponsors who pay big money to have their names and logos slapped on these speedy machines. This Honda NSR250R SP Terra Racing Replica is surprisingly subtle, however.

The NSR250R was Honda’s standard bearer in the two-stroke sportbike class that was hotly contested pretty much everywhere but the US, where vast distances, straight roads, emissions legislation, and licensing requirements [or lack thereof] meant that the class is virtually unknown to the mainstream biking community these days. The original MC16 version introduced in 1987 set the tone for the series, with a 90° v-twin, alloy twin-spar frame, RC powervalve, PGM electronic ignition, and giant-killing performance.

Of course, competition from Suzuki, Yamaha, and later Kawasaki were pretty killy as well, and the intense competition saw the bike quickly evolve into the MC18 in 1988 and the MC21 in late 1989, followed by the final MC28 that came along in 1993. This appears to be a late MC18 R6K, the middle-child version of the bike, since it lacks the larger headlight and distinctive “gull-arm” swingarm of the MC21, and the SP denotes the “Sport Production” version that came with a trick dry clutch and Magtek magnesium wheels, along with fully-adjustable suspension.

Power from the 249cc engine would have been rated at 45hp for Japanese-market bikes, but bikes intended for foreign markets and de-restricted versions can make much more. Even in restricted form, the NSR is pretty quick, with less than 320lbs wet to push around, although two-strokes require quite a bit of work to extract the available performance. If you’re interested, top speed is around 130mph, but that’s not the point of the bike. Find a tight racetrack or a set of canyon curves that would tie even a modern literbike in knots, make sure you eat a light breakfast to save a couple pounds, and spend a Sunday morning worshiping at the Temple of Lean.

Up for your consideration is a 1989 Honda NSR250 SP TERRA RACING. This bike is all original minus the full Jha exhaust system, and stainless steel brake lines. From the factory the bike is equipped with a HRC dry clutch, magnesium wheels, and a fully adjustable suspension. The bike sounds amazing and starts first kick every time. The bike  has been fully deregulated and runs absolutely great and is extremely quick despite the cc size. All fluids have recently been serviced as well as two new spark plugs.  Please view all images as this is a 30-year-old original bike with minor imperfections.The bike was legally imported into the United States and I do have a clean and clear Arizona title as well as a full set of aftermarket stock plastics still in the bubble wrap. I do encourage all bidders to please come and view the bike in person, or send someone on your behalf to inspect and view the bike. Please don’t hesitate to email for more information as well as pictures videos of the bike running if needed. 

Bidding is currently up to $5,900 with the reserve not met and very little time left on the auction. There are some minor chips in the decals and paint, and some aftermarket farkles like the steering damper, brake lines, and the front brake rotor buttons are obviously not original and are of questionable taste, but simple enough to change or remove. Although they are surprising, considering the claimed [and indicated] miles. Regardless, it is a clean-looking bike and worth a look if the reserve is set at a reasonable point.

Museum Quality: 1991 Yamaha TZR250 SP for Sale

Let’s get this out of the way up front: the seller is asking $16,000 for this bike, and that’s a big number for a Yamaha TZR250. But obviously, a thing is worth what someone will pay for it, and I’m not sure that the seller won’t get what they’re asking here, since prices have been increasing steadily on all two-strokes for the past few years. If you’re a collector for whom a couple grand one way or the other really doesn’t matter, and want the very best example for your collection, this TZR250 SP might just be what you’re looking for. Sure, $16k is a lot to pay right now for a TZR, but that might seem like a bargain in just a few years.

There are three generations of Yamaha’s two-stroke sportbike: the early parallel-twin 1KT/2MA, the reverse-cylinder 3MA, and the v-twin 3XV seen here. Personally, I love the style and general weirdness of the 3MA, especially that version of the gorgeous Deltabox frame, but the 3XV seems to be the most highly sought-after version of the bunch. There were a variety of different specification levels for the 3XV version, designated by the usual alpha-numeric gibberish: R, RS, RSP, SP, SPR. Wet and dry clutches were available, ignition and powervalves had different performance characteristics, and fairings were not always interchangeable between models. Ferreting out detail differences in these Japanese market bikes can be tricky, so experts are welcome to chime in in the comments.

The seller claims you can get 90hp from an unrestricted example which, from what I know, is theoretically possible, but at the expense of any pretense of durability. That’s pretty much race-spec, a smoky grenade you should ride with your left hand covering the clutch. Somewhere in the neighborhood of 60hp is more reasonable for a highly-tuned streetbike, and doesn’t really change the seller’s point at all, that an unrestricted bike would be much more powerful.

From the original eBay listing: 1991 Yamaha TZR250 SP for Sale

This bike is fantastic. It has 1800km (1100 miles) it is a Japanese Domestic bike which I imported personally. There is no bond or restriction from Customs you can get it on the road virtually anywhere if you wanted to street ride it.  As you prolly know the SP bikes were about halfway between a standard TZR and a customer-racing 250. Restricted it’s 50hp and less than 300 lbs. It’s a weapon – even after 28yrs!! I have been told that derestricted with basic mods you can get 90HP from these which is just insane, of course. Thanks for looking!  

From the photos and description, this thing is just about perfect, in very original condition. And that’s maybe the only issue here: in stock, restricted form, the whole gang of quarter-liter two-strokes made a government-mandated 45hp. But it really depends on what you’re looking for: a wicked weekend ripper or a perfectly preserved museum piece. And I get the feeling that a dead-stock example is the way to gamble if you’re looking at investment potential.
