Lighter Makes Righter – 1987 Ducati 750 F1B

Ducati found its Taglioni-engined twins a good match for the fledgling Formula TT series, and produced road and track versions.  This California example has apparently never seen the road, and not much of the track as evidenced by the unfettered condition.

1987 Ducati 750 F1B ( Racebike ) for sale on eBay

The F1 refers to its Tourist Trophy class, the 600-750cc segment of the race series which got its start when FIM decided the Isle of Man was too dangerous a venue.   As presented for the street, the F1 claimed 63 hp, with two valves per cylinder and 36mm Dell’Orto carbs.  The artfully crafted chrom-moly chassis and swingarm had Marzocchi dampers front and rear.  Brembo brakes are not oversized at 280mm, and the six-spoke alloy wheel sizes were staggered at 16 inch front, 18 rear.  The sub-400 lbs. weight came through judicious use of lightweight materials and drilling everything else.

Hard to expect a full ownership and maintenance history for a find like this though the seller does posit an odometer issue.  Can’t tell all from the pictures provided, but the finishes look excellent and lack the patina that not much actual use would provide.  Carburettors have been upgraded to 38mm Mikunis, and fuel plumbing had to be changed to accommodate.  From the eBay auction:

1987 Ducati F1B that was never titled for the road. The speedometer has 4 miles. I don’t believe it to be original miles. The 750 F1 was a factory prepped track bike that saw very little use. The paint is in beautiful condition and as you can see in the photos. Bike is fitted with a harness for track, with out a left side headlight switch. The bike starts and runs flawlessly. Carbs are Mikuni race 38 mm flatslides. The bike would need little work to return it to a road bike but at the end it is a original factory 750 F1. The frame paint shows no use and is in beautiful condition without any damage or scratches. The bodywork has some small spider cracks on the mono seat, fairing is in beautiful condition. The plastic windscreen shows a small crack visible in the photos.

Ducati started out in Formula TT with their 600 F2 under Tony Rutter, who laid down 4 consecutive championships.  The 750 F1 wasn’t quite so lucky, but has become an iconic model.  Special F1 editions commemorating wins at Montjuich, Laguna Seca, and Santamonica may have put Ducati on the path to continuing limited editions.  This F1B is a classic piece of exotica and has the ask to match – but looks worth a daydream or two.

Singular Simplicity: 1997 MZ Skorpion Sport

The sad thing about being a serious motorcycle geek is that most people don’t really understand my obsession with and enthusiasm for weird motorcycles. Even other motorcyclists. I was thinking about this today as I was poring over the engine of a friend’s Velocette Venom, trying to suss out the function of the little cable-actuated device at the base of the pushrod tube [compression-release, we decided]. I mean, I happen to think bikes like this MZ Skorpion Sport are incredibly cool, but most motorcyclists are ignorant of their existence. That’s a shame, since [East] German brand MZ has a storied history and basically single-handedly ushered in modern two-stroke performance when they developed the first expansion chambers for their race bikes.

The Skorpion Sport doesn’t have those, however.

What the Skorpion Sport does have is Yamaha’s five-valve single that displaced 660cc, just 6cc short of being an engine of pure evil. As it was basically an off-road drivetrain repurposed for sportbike duty, a Yamaha five-speed gearbox transferred power to the rear wheel, and the package was suspended in a tubular steel frame. The engine and frame formed the foundation for a whole range of interesting and generally very competent motorcycles from MZ, from the Mastiff supermoto and Baghira dual-sport, to the Traveller sport-tourer, Replika, and the Skorpion Sport.

Overall, the bike is simplicity itself, the purest incarnation of a sports motorcycle you’re likely to find at this price point. Weight was a hair over 400lbs wet, and handling generally considered to be excellent. Styling looks a big like a Gilera Saturno and the bike does feature passenger pegs, although there’s no guarantee there is a pillion pad hiding under the seat cowl, or included with the bike. The 1990s were weird like that.

From the original eBay listing: 1997 MZ Skorpion Sport for Sale

Looks great. Runs Outstanding. Low mileage. I’ve taken it on several long rides with no problems at all. Yamaha reliability. Made in Germany. Designed in England. Lots of Italian bits. Buyer responsible for pick up. I’ll help get it on to the transporter. I have the unsigned registration papers, and original manual. New tires. Small scuff on right side of engine where someone dropped it. It’s in the pictures. I have the under-belly fairing, and the original muffler as well. I never registered it in CA. (DMV-phobia) Bill of sale only.

There hasn’t been much interest in this MZ so far, with bidding up to $2,300 and about one more day left on the listing. That’s on the low side, but Skorpions don’t go for much more money than that right now: they’re rare, but not especially collectible. What they are is great value, with an exotic nameplate, nimble handling, stone-axe reliability. With single-cylinder classes a popular way to get into racing on a budget, Skorpions often get snapped up to be converted into lightweight track-hacks. They’re good for that, but it does seem a little sad that such interesting machines

Road or Track: 2000 Aprilia RSV Mille R for Sale

If you’re looking for a track bike, your best bet is something as modern as possible, with broad parts availability. A reliable tool for going fast as effortlessly as possible. Something completely disposable. There’s a reason you see a ton of GSX-R600s and 1000s, R6s, the occasional SV650, even a new crop of Ninja 400 and other relatively modern tackle that offer anvil-simple reliability. Basically the opposite of this Aprilia RSV Mille R in almost every way. But personally, I know I’m nowhere near fearless enough to delude myself into thinking I’ll ever be more than a B-Group trackday rider, so I’m willing to make some sacrifices to style, and this would be at the top of my personal trackday bike list.

Styling is subjective and, while Aprilia’s first foray into full-size sportbikes isn’t exactly pretty, it didn’t make the mistake of trying to out-Ducati Ducati: the looks were wild and very modern, with a gorgeous aluminum beam frame and curving swingarm. Handling felt much more “Japanese” in terms of turn-in and agility, compared to the 996’s incredible mid-corner stability. Austrian firm Rotax eschewed old notions of what made a v-twin smooth and revvy, and created an engine with a relatively narrow 60° layout kept smooth with balance shafts, while four-valves and liquid-cooling gave it power to compete with the Bolognese brutes. In addition, they included something that seemes to have eluded Ducati until pretty recently: reliability.

So it was exotic, fast, blessed with excellent handling, and surprisingly durable. And it came with lots of trick equipment straight from the factory: Öhlins components at both ends, along with a steering damper from the famous Swedish suspension specialists, and a smattering of nice carbon bits. The biggest limitation here is that the bike is sporting what appears to be largely original bodywork. Certainly, it’s painted to look the part. That makes a trackday crash a pretty pricey proposition, so if you’re really planning to flog it, perhaps some less stylish trackday bodywork is in order.

From the original eBay listing: 2000 Aprilia RSV Mille R for Sale

With a total of 2,293 original miles this was a one owner bike bought brand new in 2000. A well cared for, great riding great sounding clean bike. Has been in indoor climate controlled storage for years. No ethanol fuel was ever ran through this bike. Also on a battery tender.

I purchased from original owner with the idea of making a track bike. I reworked the seat and put brand new Dunlap SportMaxx tires on both front and rear of the bike (high speed balanced). Change oil filter (K&N), fresh oil (Motul) all new fluids for brakes and clutch (Motul) and radiator. Pingel deadman kill lanyard switch was installed.  

Bike is safety wired for tech. I removed mirrors and installed mirror block off plates, removed turn indicators, tail lights, disconnected head light, etc. All wiring was not cut and factory din connectors are all labeled and properly routed and zipped tied for ease of re-installing lights. All stock turn indicators, rear tail light, mirrors, an extra Motul oil filter, Motul oil, Motul DOT5 brake fluid, full 5 of Sunoco race fuel, are all included in sale along with a manual and factory books & key. This bike has a clear clean Ohio title in my name and is street legal with lights installed.

This bike has Full Ohlins suspension, Brembo brakes, carbon fiber fenders, chain guard, and side panels. It is completely stock except for chip and upgraded exhaust, installed by previous owner. Here is your chance to get a track made bike ready to go for cheap. I even have full Vanson race leathers and boots in another listing to make it a full race package. Can help with shipping but shipping cost is on buyer. Please check out photos as bike is sold as is and if you have any questions please don’t hesitate to ask. Thanks.

The asking price? $3,400 and that includes all of the road-legal equipment, making that a very nice price for a track-ready machine and a pretty screaming deal for an Italian exotic. I’m not the biggest fan of the RSV’s styling, but you can’t argue that the package offers tremendous bang for your buck: it looks very trick, the specification is amazing. I’ve always wanted one just like this as a track bike…

Turnkey Racebike: 1993 Ducati 750SS for Sale

Ducati’s air-cooled 750SS might seem like an unlikely candidate for a racebike build. By 1993, a two-valve Desmo twin was antiquated technology, a quirky, charming curio by the sportbike standards of the day. But although competition duties had been handed off to the liquid-cooled, four-valve superbikes by the early 90s, it’s important to remember that versions of the lighter, simpler Desmodue were powering Ducati’s racebikes all the way back in 1981.

The first Ducati to use the then-new engine was the 500SL Pantah, first sold in 1980. The Pantah engine was developed by Fabio Taglioni as a follow up to the beautifully-engineered, but expensive to build and service bevel-drive v-twins. It had single overhead cams driven by toothed rubber belts, and two Desmo-actuated valves per air-cooled cylinder. Race bikes built from this platform were light and nimble, but were eventually outclassed in terms of outright power and were typically competitive in smaller classes.

Ultimately, larger variations of the Pantah engine found their way into Ducati’s second-tier sportbikes like the 900SS and the 750SS seen here. They were sold alongside the painfully expensive 851/888 and 916 that followed as a more affordable, easier-to-maintain alternative to those much more exotic machines. Power may not have been overwhelming, but the bones are good, and those Supersports machines provide excellent handling to go with their thumping Ducati charm.

From the original eBay listing: 1993 Ducati 750SS Race Bike for Sale

1993 Ducati 750 Supersport vintage racing bike:

Ducati 750SS Spare Engine Complete 750F1 Cafe Race CCS AHRMA ($3,400)
This motor was built by Chris Boy of Motor course Performance, Fort Lauderdale FL. It was designed as a low stress motor, built with high compression pistons, Carrillo rods, lightened crank and internal gears, straight cut gears, wet clutch. Heads have custom manifolds as shown set up for FCR 4`mm carbs modest porting, standard valves and Vee Two “Daytona” gind racing cams from Brook Henry ($1500) and fresh clutch pack. Currently set up as constant loss ignition and starter plate is blocked off for cart starting. It made 79.5 RWHP at the MCP Dyno. Motor has approximately 40 miles on the most recent tune up, including valve adjustment, new clutch pack. It is in excellent condition and is plug and play. 

The seller does include a long list of included parts, and this bike appears to have been properly put together. Developing a competitive package can be time-consuming and expensive, and this appears to be a legitimate race bike built to AHRMA specifications, but $12,000 is still a hefty chunk of change for an early 90s air-cooled Ducati. Now if the seller planned to include that spare engine [sold separately!], this might start to look like a better deal. I love the air-cooled Ducatis and have long thought a Supersport would make a great trackday ride, especially considering their values until recently, but the price here seems ambitious.

Bantamweight Racer: 1981 Honda RS125RW for Sale

Today’s Honda RS125RW might be a bit obscure for most of our readers, and is certainly older than the bikes we usually feature here, but a genuine Honda Grand Prix machine is certainly worth a look whenever one comes up for sale! This one has plenty of patina, period stickers, and an apparently rare dry clutch for less weight and extra noise!

Honda’s Grand Prix racing motorcycles were based around four-stroke engines until the two-stroke MT125 was introduced in the 1970s. The MT125 was replaced in 1980 by the RS125RW seen here, and that machine soldiered on until it was replaced in 1987. The significantly updated RS125 introduced in 1987 was eventually developed into the dominant machine more familiar to most of our readers.

Powered by a motocross engine borrowed from the RC125M, the RS125R’s liquid-cooled, reed-valve engine made 30hp from 124.9cc with a bore and stroke of 56 x 50.6mm. The frame was a twin shock, steel duplex design, had disc brakes at both ends, and weighed in at 170lbs dry. It wasn’t considered cutting edge when new, but it was reasonably successful in competition and Honda continued to develop the bike and its successors as an over the counter racing machine available to younger racers honing their skills.

From the original eBay listing: 1981 Honda RS125RW for Sale

1981 Honda RS125R-W located at our shop in Santa Ana, California. The pictures in this auction were taken at our shop in Japan. This RS125R-W is in very good condition for its age. Engine has a super rare dry clutch. The previous owner said he rebuilt the engine before it was put away many years ago. RS125R-W are very hard to find now. This bike is the best we have had for many years now. And the only one we have had with a dry clutch. Bike will come with a new windscreen not mounted to the bike. There are no spares with this bike. Bike is sold as is, no returns. Look at the pictures carefully and ask questions before you bid. Sorry, no Paypal on this item. Again, bike is sold with a bill of sale, no title. Bike comes with what you see in the pictures in this auction.

The starting bid is $6,995 with a few days left on the auction and no bids as yet. This one is obviously a bit of a gamble, since parts to keep one running will be difficult to source. The engine is said to have been rebuilt, but I’d be prepared for the worst if it was my money. Experts might have a line on what they might need to actually ride it, and this bit of Honda racing history would obviously make an awesome display piece for your living room or the lobby of a business, if you just want to show it off in all its period patina.

Featured Listing: 1998 Triumph Daytona Ex Formula Thunder Race Bike for Sale

I love seeing race and trackday bikes built out of unlikely candidates like this well-prepared, race-winning Triumph Daytona T595. After all, the whole point of the Daytona in the first place was that it wasn’t pretending to be just a numberplate away from placing at Brands Hatch. Instead, it was intended as a fast roadbike, with a focus on character, build-quality, and humane ergonomics. A gentleman’s sportbike. In this case, a bike for a very fast gentleman…

The original Daytona introduced in the early 1990s was available in three or four-cylinder flavors and it was a big, burly GT to rival bikes like the Kawasaki ZX11. The second generation seen here was codenamed the T595, although it was fairly quickly renamed the 955i to avoid confusion regarding its displacement. That’s the kind of thing that never bothered Bimota, and I wonder how many people ask SB6 owners if their bike is a 600… In any event, the bike displaced 955cc and was much lighter and more agile than the bike that preceded it.

That being said, the T595 really wasn’t intended for competition: the suspension was too soft, the motor biased towards a flexible midrange, as opposed to top-end power, and it was still just a tad too heavy. But this is a Triumph we’re talking about, and sportbikes are in their DNA. Fit some stiffer suspension, do a bit of headwork, swap in some custom-ground cams, and change out the stock wheels and bodywork for some lightweight parts. Voila: racebike! It’s obviously not quite that easy, but someone clearly put in the effort here: the description goes into great detail regarding the work and parts that went into building this successful racing machine.

From the Seller: 1998 Triumph Daytona Ex Formula Thunder Race Bike for Sale

This is an off road only track bike, no street parts available. This bike dominated at the local track in the Formula Thunder class in early 2000’s. Once retired from active duty it was sold to its current owner in 2003. At that time it was taken to a well known local engine builder go through entire motor and chassis and make get it ready for its last race, a 4 hour endurance race. The motor was torn down and a full fresh build took place. Invoice provided for build. It was then broken in on the Dyno (see chart) and off to the races it went. Retired after the event, until it was brought in to us to find a new home. It had sat for a few years so we carefully went over it, good compression @185-200, changed oil, filter, flushed coolant, fresh fuel and bike came right to life!

Here is a quick list of the obvious and a note from professional Triumph engine builder Scott Zollars.

  • 885cc
  • Dymag magnesium wheels
  • Rare Yoshimura full exhaust
  • Attack Performance Triple clamps and rear suspension linkage
  • Pro Circuit Suspension re-valved front and rear suspension
  • Penske rear shock
  • Brembo Master cylinder and calipers
  • 320 mm rotors with custom caliper brackets for Brembo’s

“The cylinder head is a ported 885 from a speed triple. The cylinder liners are the aluminum with nickasil coating items from the earlier generation Super 3. In particular they are all number 2 cylinder liners as they had a tighter tolerance from the factory. The pistons were from the earlier Super 3 also as they were 12-1 hi compression pistons. The cylinder head was decked when it was ported. A final compression ratio of 13.0 sounds familiar. The cams are a custom grind from Web Cam. The valve springs are a custom set from Kibblewhite. The airbox is a crudely made custom item. However it proved to be very effective. The transmission gears were back cut. The shafts that the shift forks ride on were shortened to allow them to float in the case similar in fashion as to what was standard on R6’s etc. All rod and main bearings were the White bearings. Carillo connecting Rods. This is how I remember the bike being set up. Things may have changed since 2004 though” – Scott

From one of the local forums:

“05-15-2005, 12:47 AM – Scott Zollars was the man behind I-90 Motorsports race 885 Daytona. That bike dominated the Formula Thunder class at Pacific Raceway for four years.
Also he was involved with Jack Lilleys highly successful 595 Daytona. I think it was the first British bike to win a National in eighteen years? I know first hand that Scott is an expert with fuel injection, electronics, motors and fabrication”

Credits cards accepted, up to $150.00 documentation charge may be added.

The seller also includes a short walkaround video of the bike running and the throttle being blipped. There are obviously more sensible track-day mounts, bikes that are simpler to get parts for and faster. But if I was in the market for a $7,000 track bike, I’d be very tempted by this Triumph. It’s obviously a highly-developed machine for that kind of money, and you couldn’t replicate it for anything like what the seller is asking: just the rare parts fitted would probably be worth the asking price, not to mention the hours spent building and tuning it. And if you’re looking to go racing in a vintage class, you could certainly do worse than starting with a competitive machine like this one!

Dr. Evel – 1972 Harley-Davidson XR-750

Harley-Davidson introduced the XR-750 in 1969 in response to an AMA rule change that made their flat head racers finally obsolete.  The 1972 revision had an updated engine design and went on to an unmatched series of flat track wins and stadium jumps.  This example is fitted with the optional rear brake and a tuneable SuperTrapp exhaust.

1972 Harley-Davidson XR-750 for sale on eBay

After the quick initial conversion of their Sportster race engine, Harley took more time with Rev. 2.0 and commissioned a different layout with a wider bore and shorter stroke, and alloy heads.  In an interesting redux of the sidevalve KR engine, each pushrod has its own cam, uncomplicating cam profile and timing changes.  Power was 80 hp or better, spinning pretty well for a pushrod mill at nearly 8,000 rpm.  The 19-inch front wheel is right at the end of the Ceriani forks, so handling should be true to the 26-degree rake.  Number plates and mufflers conceal the twin-shock rear, and the tank/seat combo is fiberglass.

Offered by a Florida dealer, no history or past ownership is offered, but the eBay classified does hold promise.  Gotta love racebike details like both brake and shifter on the right peg.  XR fans will have to comment in their thoughts, however it would be unreasonable to expect anything on a dirt track racer to be original or unmodified ( or even un-damaged ! ).  From the eBay listing:

Blast from the past and a beautiful example! Inquire and we will answer ALL and ANY questions and we will try hard to get the answers. Hagerty values this at $50,000!

A redesign in 1972 resulted in a motorcycle that would be the most successful in the history of American Motorcyclist Association Racing.
Evel Knievel made the bike famous outside the fairly narrow lane of flat track racing, jumping his 1972 XR to a string of then-world records.

The right collector could take this XR in any number of directions – as raced by Roger Jr., an AMA champion tribute, or Evel Knievel lookalike.  Or home to the dirt as an amateur ?  Nothing as sensible or practical as a sportbike, but a could be a great project.

For Offroad Use Only: 2001 Aprilia RS250 Cup for Sale

By 2001, the entire quarter-liter sportbike class was basically dead, leaving the Aprilia RS250 Cup a bit of an orphan. Yamaha TZR250 production ended in 1995, Honda’s NSR250R in 1996, and the Suzuki RGV250Γ held out until 1998. But I guess Aprilia still had some of the older 90° RGV250 engines lying around, so they kept churning out bikes for a few more years. The bigger issue was their viability as road bikes: one of the biggest reasons for the classes’ demise was the increasingly stringent emissions regulations that favored cleaner-burning four-stroke engines, instead of the light weight, but very dirty two-strokes that powered these bikes. They don’t call them “smokers” for nothing…

So the 249cc powerplant was from Suzuki, with a few Aprilia-branded bits to make the claim that they’d tuned it extensively somewhat believable. The frame was an aluminum twin-spar unit like the donor bike, but what a frame: unlike the industrial units seen on the Gamma and NSR, Aprilia’s was gorgeously sculptural, as was the swingarm. Brakes were more than up to the task, since the very same triple-Brembo setup was used on much heavier bikes like the Ducati 916 and Moto Guzzi Sport 1100…

By 2001, new two-strokes weren’t legal for road use in many markets, including the US. The RS250 Cup got around this by not bothering to be a road bike. It was intended for a single-make racing series, although an awful lot of them turn up here on eBay with very few miles, suggesting folks bought them to collect and not to race. It’s not too difficult to source bits from the road-legal version if you’re looking to convert one, although that doesn’t appear to have been done in this case.

From the original eBay listing: 2001 Aprilia RS250 Cup for Sale

This is an Aprilia RS250 imported into the US for the Aprilia Cup club road racing series. It was sold as a race bike only so bill of sale only. This example was never raced and spent most of its life in a private motorcycle collection. The original owner added lighting, turn signals, horn, and other equipment typically found on a street bike. I have only ridden it 6 or 8 times in the years I have owned it but I recently went over it from nose to tail and made sure everything is in good working order. Other than the added street equipment the bike is as originally delivered by Aprilia. Having owned and road raced one of these for many years I am very familiar with them and this motor is quiet and tight. Factory shop manual is included with the bike.  Also includes a new Shorai lithium/iron battery.

The Aprilia RS250 Cup was originally a track-only machine, although the seller indicates that it’s been made nominally road-legal and that it has managed to accumulate 3,000k miles so far, and bidding is up to just $5,250 with a few days left on the auction. The projector-beam headlight isn’t stock, but actually works pretty well, although I’d replace those red-anodized fasteners with black as soon as I got the bike home. Obviously, any potential buyers should be wary if they intend to register this machine for road use, unless they just plan on converting it back to track-only configuration.
