Fresh Street Racer: 1993 Ducati 888 SP05

The Ducati 888 filled the gap between the brand-redefining 851 and the legendary 916, bumping the 851's fuel-injected, liquid-cooled, four-valve L-twin to 888cc. The inbetweener status didn't phase the bike much, though, as it was enough for Doug Polen to net back-to-back World Superbike championships in '91 and '92. Production ended in '94 as the world geared up for the Tamburini-penned 916. Ducati sent fewer than 300 to the States.

1993 Ducati 888 SPO5 for sale on eBay

This 1993 Ducati 888 SP05 is number 270 of 500, and has covered just 125 miles since its original UK delivery. The SP versions of the 888 never made it to our roads, as they couldn't get past American DOT laws. Now that the bike has reached the magic 25-year mark, it might be possible to bring it in and secure registration, though it probably should be ridden sparingly.

From the eBay listing:


We are pleased to present the opportunity to own a very rare collectable Ducati 888 SP5. This example is number 270 of just 500 made. A beautiful 1993 model having covered just 125 miles from new. This is the ultimate concourse example and the best we have ever seen

This bike is supplied with the original handbook, and will have a full belt service and MOT prior to the new owner taking possession.

The 888 was a motorcycle manufactured as an upgrade to the 851. The earlier 851 had introduced liquid cooling, computerised fuel injection and four-valve heads to Ducati's two cylinder motors. After increasing the capacity of the 851 to 888 cc they then released the iconic 888 SP5 in 1993.

A small deposit will secure this Ducati and we offer finance packages to suit and can also arrange delivery both UK and worldwide.

The bike is listed with a classified ad, meaning that the price -- about $55,000 USD -- won't change over the course of the listing.

Racetrack Refugee: 1998 Yamaha R7/R1 for Sale

Yamaha's R7 was among the last in a long line of machines from the Age of Homologation Specials, where the manufacturers competing in AMA and World Superbike racing created limited runs of insanely expensive bikes that looked like production models, but were chock full of trick bits like adjustable steering heads and exotic engine internals. For the most part, these were based on pretty common machines from each manufacturer's lineup. But in situations where nothing in the manufacturer's stable really matched their needs, companies sometimes whipped up a bike whose whole production run was designed to allow the bike to compete in a variety of racing classes. By the late 1990s, the 750cc class was pretty much on its way out as a viable category for streetbikes, but that didn't stop Yamaha from introducing their very trick and hideously expensive YZF-R7. How trick? Well the frame was claimed to have been based on Yamaha's 500 Grand Prix machine. Just 50 were imported to the US out of 500 built in total. And how expensive? Well, the R7 was $32,000 late-nineties dollars, and that was before you included the race kit that actually made it fast.

Just one problem: from the factory, the R7 made just 106hp, which didn't really provide the performance the looks or pricetag promised. The solution? Just pony up for the race kit that activated a second, dormant test of injectors and replaced the airbox for a revised part that unleashed a more appropriate 162hp but also gave racebike-like reliability. The biggest limitation of the R7 was that engine, and unleashing the full potential could be tricky and expensive, so owners that wanted to use their bikes on the road sometimes switched out the 749cc engine for the 998cc unit from the R1, which seems to have been done in this particular case. I'm under the impression that this was a relatively simple swap and, although it could be considered sacrilege, actually had several benefits: it gave very similar maximum power to the original engine, but with far more midrange, and it also meant the original engine could be saved to preserve the bike's value for future collectors. That appears to have been done here, although the seller's description does leave me with some questions.

This R7/R1 hybrid appears to have been built to a high standard by Graves Yamaha, so I'm sure they knew what they were doing and I've no doubt the bike is very special. But it would really help if the owner was clearer about what he has: he calls the powerplant a "OWO1 1000 superbike motor" but the OW01 was 749cc, although the five-valve inline four was related to both the R7 and the 998cc R1 units. The OW02 engine was supposedly based on that earlier engine and has the same displacement to conform to class limitations, but I'm not sure it can simply be punched out to a full 1000cc.

More likely, it has a later R1 engine, which was, as stated above, the simpler, much more reliable way to get the fully-unleashed R7's 162hp without all the explode-y engine drama. Maybe it's a full-factory superbike R1 unit? The seller also mentions the "half R7 and half R1 frame" which would require some very serious surgery if true. And which halves were used? Front and back? Left and right? Maybe it's the R7 Deltabox with the R1 subframe? It's also listed as a 1998 model, but I was under the impression that the bike was sold in 1999 and 2000.

From the original eBay listing: 1998 Yamaha R7/R1 for Sale

This bike was built in house built by factory Graves race team and was one of Chuck Graves personal bikes. It might be one of only two left, this bike has every goodie you could imagine on it: Brembo brakes, Ohlins forks and rear shock, superbike radiator and tank, swing arm, custom half R7 frame and half R1 frame, Yamaha OWO1 1000 superbike motor, rear Brembo brakes, thumb brake, brake lines, rearsets, Akro pipe, after market wheels, chain sprocket kit, offset triple clamps. This bike new with the race kit harness was $43,000 and only 32 came to the US that year, it is a very limited production bike, to rebuild this bike in today's time would cost over $100k plus the 1000 donor bike for parts, this bike looks like it just rolled off the race truck.

All-in-all, this modified R7 is a very cool machine, with plenty of very trick bits plainly visible, but I'd definitely want some answers to my questions before bidding on this one. Many, many questions, but worth asking, considering it is a Yamaha R7, after all. I'd especially want to know if the original motor is included, as a good chunk of the bike's value is wrapped up in its originality, and while this might be an amazing machine and a true track-day weapon, all those modifications likely hurt the collector value. As always, if you have any insight into the bike, please feel free to fire away in the comments!

Last Wild Stallion: 0-mile 2003 Aprilia RS250GP-1

The 2003 Aprilia RS250GP-1 represents the absolute pinnacle of two-stroke technology and the final gasp of the format's street-legal heyday. Quite simply, these are the most advanced mass-produced street two strokes that ever roamed the Earth. Since they were never sold in this country officially, finding a decent one is a feat.

2003 Aprilia RS250GP-1 for sale on eBay

But this 2003 Aprilia RS250GP-1 doubles down on its rarity by having never covered a single kilometer. Down to the whiskers on the tires, it is perfect and all original. It was imported from Australia with all the dealer and compliance paperwork, but is being sold in California, where ever getting it plated is a distant fantasy.

From the eBay listing:

Once in a lifetime opportunity to buy an Aprilia RS250 GP-1 with 0 miles! You now have the chance to own the final and most advanced release of the Aprilia RS250, the final version of the RS 250 GP-1 replica motorcycle. This bike is sporting official Colin Edwards and Nori Haga team decals, the colors and graphics add to the bike that represents GP 250cc class racing. This is a collector's motorcycle.

The look of the 2003 RS250 is dominated by its wrap-around fairing, designed and tested in a wind tunnel. The front mudguard blends perfectly with the fairing, and enhances the Aprilia RS 250's streamlined looks, the characteristic aerodynamic tail completes the Aprilia RS 250's racing image.

The bike was only sold in Europe and Australia. The bike has completed its new vehicle delivery and prep and has 0 miles. The tires are original (complete with tire whiskers) as is every part on this bike. The bike comes with a clear Australian registration and license plate for your collection only. It has never been registered in the USA as it was intended solely for my collection. The bike cannot be registered in California due to smog laws. I have a huge amount of Aprilia dealer promotional material for the bike that would be available to the buyer. It has an Australian compliance plate fitted as well.

Another super rare 2003 Aprilia RS250 sold offline from an eBay listing last month for $11,500 with 10,968 miles. I don't know how many 0 miles Aprilia RS250's are left in the world, but it couldn't be more then a just a few.

In addition, this bike was judged the best European Two-Stroke bike at Motocarrera's famous Two Stroke Extravaganza held in 2005 in Los Angeles, California. This event was the largest gathering of two-stroke vehicles in America when it was held. The bike was also displayed at the famous Quail Lodge Motorcycle Gathering Carmel, California in May 2016.

Contact me with serious inquiries only. I don't need to sell, so I won't accept any low ball offers.

Generally speaking, I am a proponent of riding sport bikes like they have been stolen, more or less regardless of provenance. They were, after all, built to go fast. This little Aprilia strikes a different chord, though. With such untouched splendor, it should be left as is for posterity.

Featured Listing: 1974 Laverda SFC

The 1974 Laverda SFC is the high-water mark for 1970s Italian sportbikes, representing the pinnacle of Laverda's race bike development and the final SFC offered in the states, as the US mandated left-side shift after September of '74.

The Laverda's big parallel twin made about 75 horsepower, heady grunt for an era where 100 ponies was still the stratosphere. Changes between '73 and '74 included new 36mm carbs and a dual-disk front brake setup.

Quite apart from the power, the Laverda was incredibly scarce, light suave. It is the antithesis of the Japanese race replicas, where weight and power hold sway over aesthetics.

This SFC has been updated tastefully and restored, and presents in near-showroom condition. Moto Borgotaro has a reputation for bringing the finest quality machines to market, and this SFC is no exception. The iconic orange paint, delicate and beautiful aluminum tank and signature bullet fairing are all without blemishes and the running gear is free of spots, stains or drips.

From the seller:


—By Ian Falloon (Falloon Report October 2014)

Although it was always a limited edition, even after 1973 when the factory stopped racing the 750 twin, the SFC continued, incorporating many of the developments learnt from three successful years of racing.

The 750 SFC was thus a true racing machine, built to the highest standards, that could be ridden on the street and a limited edition replica of a factory racer.

Racing experience during 1973 saw the development of a new frame and this made its way to the 750 SFC in 1974, further distancing this model from the production 750 SF2

Representative of the second US specification batch (with numbers between 17110-17166), we introduce you to #17148.
One of the most significant updates for 1974 was the pair of Dell’Orto PHB 36 carburetors, without accelerator pumps. A racing two-into-one megaphone (as on this example) accentuated the lean race replica profile, and the claimed power for the 1974 750 SFC was 75 horsepower at 7,500 rpm.

A two-into-one reverse cone exhaust system was an option on the 750 SFC. This exhaust system only fits the SFC frame.

Frame #17148
Engine #17148
Dell’Orto PHB 36mm carburetors
Borrani aluminum wheel rims
Ceriani suspension
Electron rear hub and sprocket carrier
High quality aluminum replica gas tank
Nippon Denso instruments
Smaller European taillight
Verlicchi twin cable throttle
Completely serviced

Very Rare Slingshot: 1989 Suzuki GSX-R750RK for Sale

Update 3.2.2018: My apologies, the links to the first RK we wrote up below led to bike now linked in this post, which is a second RK available from "whiteknuckle". Sorry for the confusion, I'll watch the VINs closer in the future. Good catch, James! -dc

Update 2.28.2018 This GSX-R750RK was first listed last month for $27,500 and is relisted for $24,900 buy-it-now or offer. Links updated. -dc

From the same era as last weekend’s OW01 and a direct competitor on the race track, this Suzuki GSX-R750RR is maybe the least well known of the period’s homologation specials, and it’s my personal opinion that this is the best-looking GSX-R of all time. But it’s also hugely rare, another case where they were supposed to build 500 for homologation purposes, but it’s unclear if that many were actually made. Certainly, they’re extremely hard to find here in the USA, although some did make it to Canada.

Why is the bike so rare? Well the general idea with homologation specials is for the basic platform to win races, so the manufacturers really didn’t care all that much about marketing them, and they were priced accordingly: the GSX-R750RR or “RK” as it was also known was actually a good bit more expensive than Honda’s RC30 and looked far less exotic to anyone not in-the-know. The rules only specified that you had to build 500 examples, not that you actually needed to sell the things.

Why is the bike so special? Well the RK was chock-full of trick, track-ready goodness. First of all, Suzuki used race-spec internals, along with different bore and stroke for the RK. But, counter to usual racing thought, they went from the standard Slingshot's 73 x 44.7mm back to the earlier bike's 70 x 48.7mm and used sand-cast engine cases, along with a brace of 40mm Mikuni CV carbs. Why go to a longer stroke engine? To regain some of the older bike's missing midrange torque, something the new bike was sorely lacking. The oil-cooler was updated [remember that these were oil-cooled], and a second unit was added to keep cylinder head temps under control. A close-ratio six-speed gearbox with an uprated clutch helped handle the abuse racers were likely to inflict. The swingarm was braced, the aluminum tank has a lower profile, the fairing has a revised shape and is made of lighter fiberglass compared to the stock plastic. The frame was revised as well, made thicker around the steering head, and there were updated suspension components at the front and back.

From the original eBay listing: 1989 Suzuki GSX-R750RK for Sale

Up for sale is a beautiful 1989 Suzuki GSX-R750RK GR79C with only 22,801 kilometers (14,168 miles). This rare RK is a homogilation bike from the racing division at Suzuki. JDM model. Very limited build. Bike is 100% stock except for the RUN stickers. All fairings and components are 100% genuine OEM Suzuki factory. Bike only has a few tiny scratches and handling marks from shipping. Rear butt pad is worn, however not bad but needs to be re-upholstered to be perfect. Engine is very clean, no corrosion present. No blistering in the paint. Bike appears to have never been down or crashed. This bike has a ton of curb appeal and presents itself as a bike with 1,400 miles, not 14,000. Runs like the day it was new. New battery and new fluids. Bike comes with Utah state title and is titled as a street bike for road use.

The Buy It Now price is set at $27,500 and there are still a few days left on the listing. Unlike many valuable homologation bikes, this one actually has a few miles on it. Certainly nothing to worry about and, if you plan to ride it on occasion, you at least know that it won't need a complete overhaul before you take it out for a brisk weekend ride. It's always tricky to judge from photos, but this looks to be as described and is in excellent shape for a nearly thirty year old bike... Resplendent in classic Suzuki blue-and-white with the signature red tail section, it's a great-looking machine, although the afterthought-level brake light could have been better integrated...

Carte Grise – 1986 Suzuki GSX-R750R Limited Edition in France

Spanning the globe, as Wide World of Sports used to say, in this case to bring you the thrill of a Limited Edition lightweight GSX-R750R.  In oddball JDM red and brown, the LE is a standout with only a few hundred made to homologate it for AMA Superbike racing.  This French-registered GSX-R looks great and has correct Yoshimura exhaust.

1986 Suzuki GSX-R750 Limited Edition ( France )

1986 was the second year in GSX-R750 history, with just a few tweaks from the introductory model.  Though the alloy Full Floater swingarm was extended, the aluminum frame and air/oil-cooled 100 hp engine were hallmarks of the design.  The Limited Edition had a couple of nice updates from the base model, New Electrically Activated Suspension ( NEAS ) anti-dive forks and big brakes from the GSX-R1100, along with lightweight dry clutch and close-ratio transmission.  The solo seat and fairing were quite a bit lighter than the biposto.  The entire package was around 400 lbs. dry, weighing less than most 600 cc machines of the day.

Housed in a Paris suburb, this LE appears complete and undamaged save a scratched area on the left fairing.  The owner states it has matching numbers and is registered on a grey card - indicating standard registration, which may ease import and re-documenting.  Not too many pictures and almost no history, so bid accordingly and make this your excuse to visit Paris for a pre-purchase inspection.

Surprisingly light and expensive, the Limited Edition wowed reviewers and race machines were immediately successful in endurance events, but had to wait until 1989 for Jamie James to grab the AMA crown from Honda.  A bit of a grail at this point, the LE's rarity is worth pursuing and some travel might be part of the fun.  Though "Pops" Yoshimura passed away in 1995, the company is still run by his sons with a location in Chino, California, and manages Suzuki's AMA Superbike and Supercross racing efforts.
