Early Adopter – 1983 Suzuki XN85 Turbo

Though each of the big four produced an -80's turbocharged middleweight, Suzuki's was focused on sport and is still the rarest.  This example has been on display in Sweden since 1987 and is ready for a marquis spot.

Each of the turbos were a technology showcase and showroom failure, but as ever, Suzuki jammed a helping of sportbike technique into their design.  In spite of the excess heat brought by a turbo system, Suzuki stuck with air-oil cooling and used an early version of their SACS piston squirters to keep temps under control.  The 673cc four used 12 pounds of boost to make 85 hp, helped by electronic fuel injection which was tuneable and didn't require carburetor float bowls next to a hot turbocharger.

The chassis got a healthy dose of attention, with the first road application of a smaller 16" front wheel and anti-dive forks.  The Full Floater alloy monoshock made for a sweet handling powerhouse.  Fans will see references to the 1981 Katana in the supersport fairing which flows right to the tailcone.  Brakes are big for the time at 290mm, an acknowledgement of the 550 lbs. wet weight.

I was thinking this Suzuki might be related to the Christensson MC Collection we saw at the Mecum auction in January, but it must be another collector from that mad hotbed of sportbikes, Sweden.  Though not perfect, the condition is close to museum quality, with just 2,300 miles.  There are nick here and there, and some peculiar almost-scratches on the right engine case.  Unlikely though it is, a quick look and lubrication of any rotating part would be in order before a ride.  From the eBay auction:

SUPER RARE ONLY MADE 1 YEAR (1983)
Bike has only 3697 km / 2297 miles on it and has been parked away since 1987.
Minor scratches as per documentation.
Bike is located in central Sweden (Västerås)

With just rudimentary electronics, this Suzuki turbo could be diverted from the collection back to rideability with just some seals and oils.  More likely it will get a thorough buffing and resume its spot in a collection, but RSBFS readers and writers would love to hear if anyone inspects or bids on this XN85 !

Featured Listing January 19, 2019 posted by

Featured Listing – 1995 Yamaha GTS 1000 Euro Edition

With its forkless front suspension, Yamaha's GTS 1000 was a tech demonstrator and leading-edge sport tourer. This example is in excellent shape with under 6,000 miles.

1995 Yamaha GTS 1000 with only 5,880 miles !

Besides hub-steering, which separates front suspension and steering, the GTS 1000 showed the way in other departments - electronic fuel injection and a 3-way catalyst reduced emissions for the engine from the FZR1000, tuned for 102 hp and a generous torque curve.  Big single disk brakes are found front and rear and backed up by optional ABS.  The full-featured fairing design surrounds the Omega-shaped main frame which encloses the engine.  Not without its faults, the GTS weighed like a sport-tourer but carried just 5-1/4 gallons of fuel.  Steering feel is different than a regular fork, but the first time you have to hit the brakes mid-corner can be a mind-changer.

Accustomed to premium pricing and forward looking, GTS 1000 owners were often real fans.  That's the case here, as Mike located a 1995 imported from Germany ( Yamaha stopped imports to U.S. after 1994 ), and has looked after it nicely.  Understated blue/gray livery goes well with the rarely seen panniers.  No apparent rubs or scrapes, and all expendables recently refreshed.  Mike's comments:

1995 Yamaha GTS 1000 Euro version.  This bike has Yamaha's FZR 1000 engine.  Fuel injected.  ABS RADD front fork technology.  This is a rare bike in that it is a 1995.  It was not imported into the US after 1994.  Its also has the rare "Panniers" which were optional and are the original Yamaha OEM equipment.
Very low miles, (speed is in kilometers).  New in 2018 tires, battery all fluids, oil & filter.  Spark plugs.  Runs perfect.  Everything works.  Windscreen is showing discoloration and there are a few chips.  Replacement aftermarket screens are available on eBay.  Title in my name. Located in Skippack, PA.

Developing a platform like this is important for a leading manufacturer, and pays dividends outside of the showroom.  While they could be considered commercial failures, bikes from BMW's K1 to Ducati's Desmosedici to Bimota's Tesi continue to push the boundaries in design and construction.  The GTS 1000 was sold worldwide until 1999, though it only lasted two years here.  Rare to begin with, this is a great low-mile example with up-to-date maintenance.  Mike asks $7,500 for the GTS 1000 and can be reached - here -.

Use Your Boost to Get Through – 1983 Suzuki XN85 Turbo

Vying for additional power without displacement, the 1980's saw major cycle makers attempt to tailor the excess heat and complexity of turbocharging to sport bikes.  Suzuki's entry is the rarest and this one has ultra-low mileage, and just one tangle with the mischievous elves that tip stuff onto parked motorcycles.

1983 Suzuki XN85 Turbo for sale on eBay

Suzuki based their turbo on a 673cc inline four, and used electronic fuel injection to tailor the fuel delivery through the variable throttle / boost map.  85 hp are claimed, leading to the model designation.  An early adopter of innovations like Full-Floater rear suspension, air-oil cooling system ( with piston squirters ), and 16-inch front wheel, the XN85 was a bit of a tech showcase.  Kayaba provided the suspension, with anti-dive forks.  Triple disks are big but not oversize considering the 550 lb. ready-to-ride weight.  Angular fairing and sculpted tank owe royalties to the then-recent Katana.

Detailed photos should be part of an auction with a high falutin' buy-it-now, which this eBay bike parts dealer probably knows.  Nothing a pre-purchase inspection can't remedy, however.  Some history and service record(s) would be a help, even for a bike with so many years and so few miles.  Short and sweet from the eBay listing:

483 miles - all original except petcock, last ran in December 2018. Also, have Service Manual, and original title.
Right rear tail section has scratches that can be fixed.

Suzuki's turbo was the sportiest of the big four's litter, though even at that it's more of a GT.  None were real showroom success stories, but maybe their role was more of leading edge glitterati for the dealer.  Under just the right conditions, the XN85 could woosh through the traps first, or just look great on the sidestand.  Either way the XN85 can provide liter-size performance from a boosted mid-size, and maybe the make offer button will let us know whether this is a survivor or museum piece.

Walks like a Duck: 1991 Ducati 851 Strada

Ducati is responsible for some of the most iconic motorcycles in the world. They are also purveyors of more marketing ploys than any other manufacturer, as evidenced by the endless parade of Limited Edition models. Therefore, words like "special" and "rare" are used so often as to appear meaningless. But limited numbers aside, Ducati has made some revolutionary leaps along its long history, cementing their place in motorcycling history with truly milestone machines. Not content to simply evolve one step at a time, at certain points in history Ducati doubled down on a new idea, catapulting forward along the performance curve. The introduction of the 851 was just such a moment. Today's bike, a 1991 851 Strada, is a good example of that revolution.

1991 Ducati 851 Strada for sale on eBay

If you think about the major technological jumps prior to the late 1980s, Ducati went from being a small bore, single cylinder manufacturer to producing twins. The L-twin configuration evolved over time, but was invariably a small step forward along the same route. The introduction of the Pantah could be seen as a leap, but in reality that move was more towards efficient production than outright performance. The Pantah was essentially the same air-cooled, two valve desmo twin as the bevel drive that came before, with only mild steps in go-power. With the 851, however, Ducati turned their own ideas of performance on its head. Simultaneously introducing liquid cooling, fuel injection AND a four valve, desmo actuated head, the 851 was a massive step forward from a technology perspective and performance. Did it work? Raymond Roche, participating in World SBK, took 3rd overall in 1989, was champion in 1990 and came in second in the two years to follow.

From the seller:
Ducati 1991 851 Strada, mostly original condition 14,600 miles.

Stored in Las Vegas Nevada for 8-12 years by the 2nd owner. Condition was not damaged or crashed.

Work that's been done since Nov 2017:
Major service including valve and shim adjust, new cam belts installed, degree the cams and clean and adjust throttle bodies by a qualified Ducati service tech.

New parts include:
fuel pump
fuel filter (Mahle)
Air Filter (BCM)
all fuel lines, inside the tank and out, plus clamps
cam belts (Exactfit)
radiator hoses and water pump hoses (Samco)
clutch master cylinder (Brembo)
front brake master cylinder (Brembo)
stainless steel clutch line (Galfer) and slave cylinder
chain (DID)
sprockets
Dunlop Q3+ tires
oil (15/50) full synthetic and Ducati filter,
tinted windscreen (Zero Gravity)
lithium battery (Shorai LFX18A1-BS12)
new voltage regulator

Plus, brakes have been flushed and radiator has been flushed. Left and right fairings have been painted.

Also I chose the very rare, period correct carbon Termignoni high mount exhaust and they sound beautiful. There is also a header modification, see pics. Other special parts included are rear Ohlins shock with remote adjuster. Ohlins steering damper.
Included with the bike are the original mufflers, passenger footpegs, owner's manual, one key and original windscreen.

Like many Ducatis, the 851 was released in a few different flavors. What you see here - the Strada or street edition - was the base model. This is not a homologation bike, although the basic platform is the same to the SP series. The Strada was the most streetable, complete with a passenger pillion hiding under the color coded tail cover, and nifty passenger grab handles that pivot out from beneath the seat. 1991 and 1992 were the last years of the 851 - the 1992 SP versions of this model actually contained a 888 motor, although the Strada remained an 851. But this speaks to the robustness and longevity of the basic mill, as even the 888 eventually became a 916 while still being badged as an 888. This is a milestone bike for Ducati, and the platform that won SBK victories and birthed the 888 and legendary 916.

Today's 851 Strada example looks to be in great shape - with wonderful photos. Mileage is reasonable considering you are looking at a 27 year old performance bike. There are a few added farkles in the manner of tinted windscreen and carbon bits, and the high-mount carbon Termis which look great. They interfere with the passenger pegs, however, so those have been removed (but are available with the sale). The Ohlins upgrades are choice, to be sure. The add ons and upgrades do not cause concern. The seller notes that both sides of the fairing have been painted - with no comment as to why. It may have been simply cosmetic, as there is no real evidence of the bike being down. Either way, it looks great in the pictures, appears to be very clean and cared for, and with those Termi cans I'm sure it sounds incredible. A big plus is that all services have been recently completed.

Well-preserved 851 examples have held up in value reasonably well. This was a watershed bike for Ducati, and it continues to be a sought-after model. This particular bike sits below $6k at time of writing, with reserve not met. No telling how high the reserve is set, but I would estimate somewhere around $7-8k would be in the money. We have definitely seen these cross the auction block for less, but the market can be a funny thing. Just check out some of the comments on the more rare examples of Ducati exotica featured in the pages of RSBFS to read comments such as "I remember when you could pick up one of those for just $xxx..." Check out the auction here, as this bike is currently a bargain. Will it close that way? What is the current market temperature for a beloved Ducati model (albeit non-homologation base model)? Watch on, and good luck!!

Some Assembly Required – 1998 Moto Guzzi V10 Centauro Sport

Moto Guzzi cross-pollinated their 1990's unfaired sport model with the newly developed 992cc four-valve V-twin, the result being the V10 Centauro.  Calendar-girl bodywork surrounds the air and oil-cooled beast within, tuned down from the Daytona 1000's peak but still happy to rev to the 8,400 rpm limit and crank out 95 hp.  This one has been rendered a little more naked than usual, but the auction includes all the stock parts and some neat touring accessories.

1998 Moto Guzzi V1 Centauro for sale on eBay

This era of Guzzi combines their recent overhead cam engine with premium components and styling by the late Luciano Marabese.  The powerplant is the star of the show, Weber fuel injection helping push 78 ft.-lbs. through the 5-speed and out to the natural shaft drive.  Top-of-the-line suspension from WP, Bitubo steering damper, brakes from Brembo, and wheels by Marchesini set the scene for a undeniably European experience.  Old enemy gross weight is present but held low in the picture and handling is helped by a rigid chrome-moly backbone chassis.

Evidently in between plans, this Centauro has had the bikini and engine fairings removed, and except for the oil cooler hanging out there, looks just as well for it.  Possibly making ready for a tour, as a couple of different seats are included as well as a set of Hepco-Becker bags, which from my BMW days are without equal.  Not mentioned but it might be an aftermarket exhaust or cat bypass.  Pictures aren't high resolution, but the owner does offer these comments in the eBay auction:

One owner, excellent original condition with 8,620 miles. Always garaged. Only in the rain three times and has zero damage.
Comes with all its original parts including the following three which were removed when it was brand new: Headlight/dash cover with clear air foil, Oil cooler bezel and catalytic convertor.
Also comes with following new parts: Luggage rack with mounts, Hepco Becker Junior 40 liter Hard bags with mounts, Hepco Becker Junior 40 liter rubber liner set, one pair original grips.
In addition, comes with following used parts: Original tires,  Factory seat, Factory seat with extra passenger padding. All original hardware, computer chip, Original owners manual, Shop manual, Parts manual.

Looks like the new owner will have all the options - a new-looking machine with choice of seats, and factory fairings or not.  Luggage, well, if you must.  Reviewed as eager to run and needing firm direction, the modern twin can propel the Centaur to more than enough speed to make the auction winner consider replacing the windshield fairing.  Stock or updated, local or long distance - which direction to take this rare and quintessential Guzzi...

Ram Air Direct: 1998 Suzuki GSX-R750 SRAD for Sale

"Ram air" was a very 90s gimmick with dubious benefits, especially on the road, but they gave bikes of the 1990s like this Suzuki GSX-R750 SRAD a distinctive style, with oversized fairing nostrils and large intake tubes that curved through the rider's view and into the top of the tank to pressurize the airbox. Well "ram air" implies airbox-pressurization at least, but the reality in this case was more form than function. But that minor point aside, the new model was a significant milestone in the history of the Gixxer, and there are very few remaining in this kind of clean, low-mileage condition.

After generations that saw Suzuki's range of sportbikes getting more refined, but ever heavier and slower, the 1996 GSX-R750 SRAD and the smaller 600cc version finally reversed that trend. Suzuki's new Ram Air Direct model was really a complete overhaul of the existing GSX-R: an entirely new aluminum beam frame with claimed ties to Suzuki's GP bike replaced the cradle design, the liquid-cooled engine was narrowed by moving the cam-chain to the end of the block, and basically everything was made smaller and lighter, more compact. It debuted with a bank of carburetors, but the 1998 version seen here added fuel injection.

The result? A bike that was, marketing hype aside, as light as a contemporary 600: 395lbs dry, almost 45lbs lighter than the previous version, with a screaming, 128hp rev-monster motor and a very slick six-speed box that you really needed to abuse if you wanted to make good progress up to the new Gixxer's near 170mph top speed. But that wasn't a problem because the new Gixxer liked abuse. Fully-adjustable upside-down forks helped the bike handle and the six-piston calipers up front may have fallen out of fashion, but certainly look pretty trick.

No one I know seems to be able to clarify for me: do you say "es ar ay de" or do you say "srad" when talking about these bikes? When I ask people keep looking at me like, "Hey, I thought you were supposed to be the expert." However you say it, the SRAD is a nearly classic sportbike with the handling, if not the outright power, to take the fight to modern machines. But throw on some fresh rubber, modern brake pads, and a set of steel-braided lines, and this could be one fun bike with the performance to go with all that nostalgic 90s style.

From the original eBay listing: 1998 Suzuki GSX-R750 SRAD for Sale

1998 Suzuki GSX-R750 fuel-injected with only 8,000 actual miles! 100% stock. Adult owned! Looks and drives like new! Never dropped! Always in a garage! Has a factory Suzuki bike cover, rear seat, tie-down strips, color-coded tank bra. This is a must see! Turns heads wherever it goes!

I've spared you the all-caps listing and deleted a whole bunch of extraneous exclamation points. You can thank me later. The seller's enthusiastic writing style aside, this is a very clean bike with a clean title and just 8,000 miles. It'd probably be even more desirable in classic Suzuki blue-and-white, but I'm sure the more subtle red-silver-black seen here has its fans.
