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.

Boosted Optimism: 1985 Kawasaki GPz750 Turbo

You are looking at what Cycle magazine dubbed the fastest motorcycle of 1985. Ripping off a quarter mile faster than liter bikes of the day, the Kawasaki GPz750 Turbo took the latest fad and turned it into a very sharp weapon indeed. Easily the most potent of the Turbo set, the GPZ750 Turbo pushed the boosted boundaries further than any of the Big Four. Yet despite the performance possible, Kawasaki failed to achieve success with their Turbo offering – much like the rest of the Big Four. Turbos screamed with graphics, torque and power, but generated few sales.

1985 Kawasaki GPz750 Turbo for sale on eBay

Kawasaki bolted a Hitachi HT-10B turbocharger in front of the engine, positioned as close to the headers as possible to reduce lag. Utilizing digital fuel injection, the air-cooled, transverse four-stroke in-line four was otherwise comparatively simple in design. Kawasaki engineers raided the parts bin, adding some strengthening to the normally-aspirated GPz750 block handle the Turbo pressure. The top end came from the more conservative KZ650, lowering the compression ratio to a range more compatible with a turbo and pump gas. Expect approximately 95 unfettered horses from this combination.

From the seller:
YOU ARE LOOKING AT A 1985 KAWASAKI GPZ 750 TURBO THAT I HAVE OWNED SINCE NEW. THIS BIKE LIVED ALL OF ITS LIFE IN A CLIMATE CONTROLLED ENVIRONMENT. THE BIKE HAS NEVER HAD FUEL IN ITS TANK, NEVER BEEN STARTED OR HAS HAD ANY ELECTROLYTE PUT INTO THE ORIGINAL BATTERY. MOTORCYCLE WAS PICKLED WHEN NEW AND MAINTAINED THAT WAY THROUGH OUT ITS LIFE. I DON’T KNOW HOW MANY ARE STILL OUT THERE IN THIS CONDITION, I’M THINKING VERY FEW IF ANY. BIKE IS STILL ON MSO, NEVER REGISTERED. I HAVE ORIGINAL OWNERS MANUAL AND BROCHURE. THIS IS A CHANCE TO OWN A BRAND NEW PIECE OF MOTORCYCLE HISTORY. I HAVE MORE PHOTOS IF NEEDED. TIRES ARE STARTING TO SHOW THEIR AGE WITH A LITTLE CRACKING ON THE SIDES, REMEMBER THEY ARE 33 YEARS OLD. PAINT IS FLAWLESS AS IS THE REST OF THE BIKE. PUT IT IN YOUR OFFICE OR MUSEUM , IT IS CURRENTLY IN ONE OF MY LIVING ROOMS.

The Turbo era has remained a relatively underperforming element of the collecting world. Sure, Turbo bikes are rare and unique – and slowly (glacially) gaining in value over the years. However they have failed to ignite the collector world just as they failed to ignite showroom fires back in the 1980s, and just as they failed to deliver on “literbike performance” from a smaller package. One might be willing to call the entire Turbo era a wholesale failure according to nearly every standard by which we compare motorcycles. Those might be harsh words, but the unfortunate reality of this particular segment of our two-wheeled universe. These words, by the way, come from an owner…

This particular Turbo GPz is perhaps the last “new” bike of its type in the world. Zero miles, never filled with fuel and original battery and tires make this a unique find for the right collector. And it would need to be a collector, as after sitting this many years unused, considerable care would need to be taken to turn this back into a rider. But riding it would destroy the value of this zero mile example, making this a museum piece at best. And what price does a brand new 1985 model go for? Would you believe six figures? Me neither. Props to the seller for asking a huge sum, but not riding the fastest quarter miler back in ’85 does not necessarily escalate the value tenfold. Yes, it can only be new once – but few bikes make it to the $100k milestone (and those are far more coveted models). Still, it is a cool time capsule worth looking at. Check it out here, and then jump to the comments and share your thoughts and experiences with Turbo bikes. Good luck!!

Hot Air: 1982 Honda CX500 Turbo

Imagine the scene in Honda dealerships back in 1982: Buck Rogers – your bike is ready. One can only imagine what the buying public thought of a futuristic, turbocharged rocket ship that offered liter-bike power in a 500cc format. Unfortunately, the reaction from the general public was not to immediately rip open their wallets and buy one. Complicated, heavy, expensive and more compromising than riders (and buyers) wanted, the Honda CX Turbo lineup survived only a few, short years before being closed down completely. Produced in very low numbers, these Turbos have half of the “supply/demand” equation on their side. Unfortunately, even fewer buyers seem to want these bikes today, making them an interesting investment conundrum. Relative scarcity does not automatically equate to “desired” – or valuable.

1982 Honda CX500 Turbo for sale on eBay

Public opinion be damned. These bikes are some of the finest produced by Honda during this era. These are cutting-edge bikes – including turbocharging, liquid cooling, computerized fuel injection – all during an era where the archaic, air-cooled GPz still hunted in the canyons. This was the promise of the future, delivered on a neon orange & pearlescent canvas, plenty of gold accents, yards of ABS plastic bodywork, and enough “TURBO” badges to make people think you went nuts with a J.C. Whitney catalog. It is different – very different. And that is both the glory as well as the failing of the Honda Turbo lineup. People want the same, only better. Honda delivered a sport touring bike (likely because it was impossible to package all of the tech in a sport bike sized machine) that was neither really sporty, nor really touring. It was an in-between bike that screamed loudly, but never really said anything that people wanted to hear. It was a monumental advancement, and an utter flop. And you will have to pry mine (a 650 model) out of my cold, dead hands.

From the seller:
Beautiful 8000 mile example of this cool turbocharged touring bike. I got his from the original owners estate sitting in the back of the garage. It had been sitting for years. I resurrected it and drove it several hundred miles and love it! but i’m a harley and triumph guy and although I like all bikes it really is not my type of bike. But more about the bike, it runs great and drives great has the original owners manual with the tire gauge and the only thing I did to get it going was replace the fuel pump and rebuild the petcock and it runs beautifully. All the gauges work great. It has a few scratches here and there but nothing too noticeable. Original paint!!

Today, everything said about the CX500 Turbo back in 1982 applies. It is big, heavy, complex and different. It’s still expensive, although time has not been supportive of the overall value. Prices on these models appeared to peak around 2010. It’s hard to believe that they will not still appreciate due to novelty and rarity, but one will likely need to another round of 1980s nostalgia to return before that happens.

This pretty (in the eyes of this beholder, at least) CX500 Turbo one is listed for $5,000 in a Buy It Now classified, with the seller open to offers. That is fair money for a 8,000 mile example of a rare bike, and far below the top dollar we have seen asked in the past. There is some damage noted to the hard to replace bodywork, so make sure you do your homework first. Check it out here, and then share your thoughts. Investment opportunity or just something different to own and ride around? Good Luck!!

Rev. 1.0 – 2000 Triumph TT600

Taking the sportbike fight right downtown, Triumph’s all-new 600 made a valiant run at the big four.  Light weight, nice handling, and quality components, it unfortunately had to be shipped before the fuel injection could be adequately tweaked.  And though software updates have corrected the throttle response issues, the damage to the reputation caused the TT to be superseded after only three years.

Triumph’s twin-spar alloy frame carries 43 mm Kayaba forks and monoshock, both fully adjustable.  Quality Nissin brakes use dual 310 mm front rotors and 220 mm rear.  The rounded full fairing incorporates two fresh air intakes above the fork legs.  At a time when most manufacturers were using four carburetors, Triumph made a big wager on Sagem electronic fuel injection.  Peak power was competitive at 110 and nearly 13,000 rpm, but rideability suffered from the faulty fuel injection map.

With just about 8,500 miles, this TT looks great with its polished exhaust and recent tires.  The mid-west owner says this in the eBay auction:

Here for sale rare 2000 Triumph TT 600 in excellent condition.  The bike is running, riding and shifting excellent and has only 8441 miles (as of today).

It is 600cc 4 cylinder water cooled engine with 110hp and 68Nm. 6 speed and 154mph top speed.

Very nice example of British sport bike.

Most TT600’s received updated software under warranty, but it might be worth checking the maintenance records on this machine.  Triumph’s return to the sportbike market should’ve been a great success.  Once the fuel delivery woes were sorted, the bike got great reviews as a nicely equipped sharp handler – maybe without Japanese street cred but a fine start.  This one looks smart in red and appears to be a cared-for example, might end up being a bargain.

Muscle Beach – 1998 Moto Guzzi V10 Centauro Sport

Using the innovative Daytona 1000 engine, and occupying a more boulevard bike place in the line-up next to the 1100 Sport, Guzzi’s V10 Centauro was fun as a styling exercise and a powerful grocery getter.  Though the basis for the modern V-twin was designed in 1971 by Lino Tonti, a significant upgrade was made in the late 1980’s which resulted in the 4-valve single overhead cam engine.  The 1997-2000 model bridged the gap until the fuller line of 1100cc machines was ready for the showroom.

Actuating the four valves from a cam in the upper side of each cylinder head, and with fuel injection, the 992cc twin results in 95 hp and 65 ft-lbs. torque.  In a departure from their dual downtube, the V10 uses a tubular backbone frame with the engine serving as a stabilizing member.  Suspension recieved some attention with WP of the Netherlands supplying inverted forks, and monoshock for the shaft drive system.  Brembo supplied 320mm floating front brakes with 282mm rear.  The bodywork is a 90’s look back at the Le Mans, with small headlight fairing and chin spoiler in a bold two-tone arrangement, with the engine also finished in gray.

Looking very good save some rash on the right head from what appears to have been a zero-speed tipover, this Centauro has a sorry 1,500 miles.  Head protectors should’ve prevented that but were possibly added afterward.  The only upgrade appears to be the polished Staintune exhaust.  Not much about the history is available but the California dealer says this in the eBay auction:

This bike is one of only roughly 3,600 made over a period of 1997-1999, only a fraction of that were imported into the U.S. making this a very unique cycle. It starts up, runs, and rides great. is equipped with a Staintune exhaust and a “chip” to remap the efi. The bike was a one owner bike before we acquired it. From what I can tell it is still on the original tires.

A peculiar beauty, this half-man half-horse is a good one for Guzzi-sti or fans of Italian design.  There is even a fan site with a lot of good info.  Reviewed as a torquey, fun-to-ride powerhouse, the lean running of 1990’s EPA requirements have likely been solved by the aftermarket exhaust and chip.  Parked for too long to put right into service, the new owner will want to do all the rubber and fluids before departing.  If not for the track or cross-country, the Centauro is a pretty distinctive way to get around town…

Improving the Breed – 1993 Moto Guzzi Daytona 1000

A dentist turned Moto Guzzi racer, Dr. John Wittner won several titles in the mid-1980’s, and lent his hard-earned expertise to the factory during the development of the 1000cc Daytona.  Along with some consulting from Raceco ( an English racing tuner that had worked on the exciting Daytona racing prototype ),  the collaboration produced the 4-valve 992cc V-twin along with a new frame design, and resulted in the Daytona 1000.

Using four valves per cylinder but single overhead camshafts, the new Guzzi engine almost broke the 100 hp per liter mark with 95 hp, but electronic fuel injection ensures great flexibility under way.  Nice two-into-cat-into-two exhaust.  The new chassis connects to Marzocchi fully adjustable forks and progressive-linkage White Power monoshock rear.  With 64 ft-lbs. torque there’s no need for more than a five-speed transmission to turn the archetypal shaft drive.  Brakes are industry standard Brembo, 320mm dual front disks and 260mm rear.

20151104 1993 moto guzzi daytona 1000 right rear wheel

With only 4,400 miles, this Daytona has led a quiet life at the back of the garage, and looks great for it.  Substantially stock except for the Corbin solo seat, the owner also has a rare set of fairing lowers, though they are not pictured.  From the eBay auction:

For selling consideration i am offering my absolute favorite Moto Guzzi, 1993 Daytona V4, #26, purchased from the second owner, i had the bike in my possession for a while and recently i decided to sell, full serviced with new belts, fluids, oil but on original tires. This bike had seen minimum use and always kept indoors, is in Excellent condition and shows minimum wear , has the period correct LaFranconi pipes but original are mint and included with the sale. I have the manual and tools kit, service manual and most important the bike comes with lower fairings, unobtainable, these fairings were made by DeAgostini in Italy and are a perfect match, was told only 2 sets were ever made, not sure if is true but i have never seen another set. Bike starts easy and runs very well, everything works, i kept the bike on original tires but if someone would be interested to do some serious riding i’d recommend to replace with fresh rubber.

20151104 1993 moto guzzi daytona 1000 binnacle

Re-incarnating the long, stable Le Mans under the Daytona name, the 4-valve engine was discontinued after only a few years, but the nice-handling Daytona helped carry the marque to the turn of the century and the 1100cc engines.  The torquey drivetrains are long-wearing and this bike should be great to return to service.  Or you could leave the original tires on it, put it on display again, and preserve it for the next owner.  Either way, put those fairing lowers on and send us a picture…

Early Tamburini effort : 1991 Ducati Paso 907 IE

Here’s one we haven’t seen on RSBFS in a few years, a Ducati Paso 907 IE.

paso1

The recent post by Mike of a pair of first gen Honda 600 F1’s got me thinking about the impact those bikes had other motorcycle manufacturers.  Here is one, a Ducati Paso 907 IE.

I have heard the styling of the Paso been described as everything from “misguided” to “bizarre” to “an insult the Ducati name”.  But what a lot of people don’t know is the Paso was actually designed by the same Massimo Tamburini who would later go on to design the Ducati 916, MV Agusta 750 and earlier helped to found Bimota.  The Paso was one of Tamburini’s first efforts when he was hired at Cagiva (who owned the Ducati name at the time) and he decided to streamline the bike and hid the majority of the internals inside a close-fitting fairing system.  This was the “hot” style at the time and is similar to what Honda was doing with their new CBR/Hurricane series which was introduced the same year.

paso6

1991 Ducati Paso for sale on ebay

The Paso came with an oddball front fairing you couldn’t see through and an air cooled 750cc engine that had the rear cylinder reversed so both cylinders could share the same carburetor .  The initial 750cc Paso models were underpowered and had both cooling and fueling issues so in 1989 a new version of the Paso was produced with a new 904 cc engine that thankfully included liquid cooling.  While this resolved the cooling and power issues, intermittent fueling issues still persisted so in 1991 Ducati introduced the Paso 907IE (Iniezione Elettronica).  The 907IE replaced the oddball carburetor setup with a Weber-Marelli fuel injection system   NOTE: The 907 IE also featured increased power and upgraded 17 inch wheels which gave the bike more stability.

paso7

Even with the improvements incorporated into the 907IE edition, the final Paso wasn’t a tremendous seller for Ducati;  when production ceased in 1992 only 2,303 907IE’s had been built.  NOTE: I have read that a lot of the technology from the 907IE would go on to be incorporated into the Ducati Monster lineup but cannot confirm this.

This particular Paso looks to be incredibly clean.   Seller indicates recent service by a good dealer (Ducati of Minneapolis who i have personally dealt with and will vouch for).  The only aftermarket pieces appear to be exhausts and a seat.

Here is what the seller has to say regarding the condition

  • Just had full service, cams and valves, oil,etc. from Ducati of Minneapolis.
  • Not one scratch on the original paint.
  • Dealer installed Italian mufflers, sound is awesome, not too loud but not too wimpy.
  •  New tires and high dollar light weight battery.
  • All gauges, lights, and even the clock work perfect. 

pas04

paso3

So now we come to the question of what is this Ducati Paso worth?  Well even though the odometer is reported to be about 17,000 miles, bidding is already over the KBB retail price and reserve isn’t met.  This shouldn’t be a surprise since only around 2300 were produced, the condition of this example looks to be excellent, and the seller indicates recent service   It may not be the prettiest Ducati ever made but this seems like a bike that will increase in value going forward.

Turbo Time II: 1983 Suzuki XN85 Turbo

XN85_1

Welcome to Turbo Time – the long play edition!

XN85_4

Yes, as rare as these bike are in the US, here is the second XN85 Turbo we have found within a day. Listen up collectors: these don’t come along very often and they are not that expensive. If RSBFS history is any indication, the XN stream will dry up and we won’t see another until at least Thanksgiving. The postman may ring twice, but opportunity rare does the same.

XN85_9

From the seller:

The Suzuki XN85, released in early 1983, is a turbocharged motorcycle. It was designed as a sportbike. The name came from the fact that it produced 85 hp. It featured the first factory 16-inch front wheel, which was previously seen only on race bikes. It also had low clip-on handlebars, rearset foot pegs and a single shock rear suspension, called the Suzuki Full Floater.

The engine IS A 650 5 SPEED, with boost kicking in around the 5,000 rpm mark. It pulls strongly from that point. While the XN did not have the power of other sportbikes, it had extremely good handling.

THIS XN IS IN GREAT CONDITION AND SPORTS ALL THE ORIGINAL EQUIPMENT. TIRES AND BATTERY ARE IN GREAT SHAPE. SIMPLY, THIS IS A GREAT EXAMPLE OF SUZUKIS TURBO.

TAKE A LOOK AT THE PICTURES AND ASK QUESTIONS.
TANK IS A SLIGHTLY DIFFERENT SHADE THAN THE REST OF THE BIKE.

There is a clear Title.

XN85_3

This is a US-spec bike (not Canadian), which places it a bit more on the rare side. That being said, there is little price or desire difference between the two from a collector standpoint, so go with the best condition you can find. This particular bike has had some strong interest, with the bidding up to $4,350 (reserve not met) at the time of writing. This is still low money for a great handling motorcycle, and the fact that there were only ever a few hundred brought into the country only makes it better. To check out this distinctive booster from another era, click the link and jump over to the auction. A turbo spinning will keep you grinning!
