Slingshot Superbike: 1989 Suzuki GSX-R750 for Sale

When I got into bikes, it was easy for me to indulge my existing bias towards European machinery, since Japanese bikes were garishly colored and festooned with neon graphics, with silly names [Ninja? Katana? Really?], owned by posturing riders who thought t-shirts, sweat shorts, and high-top sneakers were appropriate riding attire. Welcome to New Jersey, circa 1990. I've since learned the error of my ways and, although I still prefer European bikes, the second generation of the Suzuki GSX-R750 is one of my favorite motorcycle designs of any era.

Sure, the double-cradle frame design was fairly primitive and had been superseded by modern aluminum beam units like Yamaha's Deltabox, and Suzuki's oil-cooled inline four experiment ultimately gave way to the liquid-cooling used by the other superbike manufacturers, but Suzuki made the somewhat outdated package work just fine on both road and track. The Gixxer always had a bit of a bad-boy image that makes them far more collectible today than Yamaha's more technologically advanced machine.

The second-generation machine is often referred to as the "Slingshot" to differentiate it from the earlier "Slabbie" models, supposedly in reference to the quartet of semi-flat-slide carburetors, but I've never seen any part of the things that actually looks anything like a device used to fling small projectiles. It retained Suzuki's Advanced Cooling System that was meant to simplify and add lightness by eliminating a coolant-filled radiator and kept temperatures under control using a high-capacity oil system.

Bore was larger and stroke shorter than the earlier bike to increase the bike's appetite for revs and make the powerplant more suitable for competition. Although that backfired a bit when racers complained of a lack of torque, and Suzuki's homologation GSX-R750RK reverted to the earlier bike's bore/stroke dimensions. Wheels went from 18" to a more modern 17" and the fairings were redesigned, but it kept the twin-headlamp endurance-racing style of the original bike. Dry weight for this version was a claimed 419lbs, and the bike made 112hp.

“Excellent condition Classic Superbike”

1989 Suzuki GSXR750 with clear title in outstanding condition. 10k miles on new motor. Same year (89 short stroke) motor as original. All gauges and directionals work. Mild restoration including brand new NOS stock upper and seat cowl. Freshly painted rear wheel with new wheel bearings and brand new Battleax tire.

Some of the mods are as follows.

  • 38mm CV Carbs jetted perfectly with filters and Yoshimura carb cover
  • Freshly painted 1992 Rear wheel/cush drive/shock with 180 Bridgestone
  • Toby steering damper that really works. Also forks and Shock recently serviced 
  • Brand new NOS stick Suzuki upper
  • Brand new NOS Suzuki rear seat cowl
  • Full Yoshimura Duplex exhaust with header wrapped header

This bike is a great running bike I've had fun with. It's not a perfect bike cosmetically bit very close. Some nicks here and there nothing bad, no dents in tank etc. Still represents VERY well for its age and can be put into a collection as is. I do have the lowers in very good condition and will post pic of them shortly. Also included is side mounted oil catch tank.

These bikes are near impossible to find in this condition so don't miss out! Will ship but buyer to arrange all details. I can be here to meet the shipper but that's about it.

The low miles on the motor are nice if you're looking for a bike to ride, but may turn off numbers-matching purists. The change to an updated, wider 5.5" rear wheel allows that 180-section tire to be fitted, since the original was a 160. Not too hard to find today, and should make for a more agile bike, but not as cool-looking. And note that the seller does have the fairing lowers, although they're not pictured at this time. I believe removal facilitates cooling of the oil-boiler engine and improves ground-clearance, but I think the bike does look much better with them on. Overall, this could be a very nice, usable superbike for a buyer looking to relive their youth but not fussy about complete originality.

Featured Listing: 1986 Suzuki GSX-R 1100

For those readers of a certain age, the 1980s were an amazing time to ride. Motorcycles were making quantum leaps in terms of performance, and technology was reshaping the design elements that we take for granted today. Take for example this wonderful 1986 Suzuki GSX-R1100. Only two years previous one of the top dogs of the sport bike world was the GPz1100 - an air cooled, two valve per cylinder dinosaur that had became technologically extinct. And while Honda went full bore into the world of liquid cooling (along with a size and weight penalty), Suzuki gambled with an innovative solution of air/oil cooling, saving precious weight and creating the lightest of the heavyweight hitters.

Featured Listing: 1986 Suzuki GSX-R 1100

The Suzuki Advanced Cooling System (SACS) employed two oil pumps, an enlarged sump to hold additional oil, and an oversized oil cooler. By employing the engine oil as both a lubricating medium as well as a cooling source Suzuki reduced the complexity of the GSX-R while also reducing weight. And this was no accident: Suzuki experimented and developed the concept in the revolutionary (and rare) XN85 Turbo. A close look at the early GSX-R engine cases and heads show the same fins as utilized by air-cooled motors, this being used as a secondary form of cooling (and both free and lightweight). The rest of the motor was closely based off of the original GSX-R750, but with larger bores and various changes to handle the additional stress. With four valves per cylinder fed by four Mikuni flat slide carbs, the big Gen I Gixxer offered 125 horsepower through a 5-speed transmission. That was enough for high 10s in the quarter and a top speed in the 155 mile per hour range. Heady stuff indeed.

From the seller:
COMING OUT OF MY PRIVATE COLLECTION IS MY 1986 SUZUKI GSX-R 1100. THIS BIKE HAS BEEN CUSTOM PAINTED A FEW YEARS BACK IN 1987 SUZUKI BLUE AND WHITE WITH AN ADDED RED STRIPE. THE PAINT WORK WAS DONE TO MUSEUM QUALITY STANDARDS BY THE PREVIOUS OWNER IN BIRMINGHAM ALABAMA. THE BIKE WAS ONE OF THE HIGHLIGHTS OF HIS COLLECTION UNTIL I ACQUIRED SOME YEARS BACK WHEN HE STARTED SCALING DOWN HIS AMAZING MINI MUSEUM.

THE BIKE WAS SET UP FOR A SLIGHTLY MORE UPRIGHT SEATING POSITION BY ADDING VINTAGE PERIOD CORRECT CLAMP-ON RISERS, RAISING THE BARS 60 MM. TO FURTHER ACCOMMODATE THE RISERS THE FRONT UPPER COWLING IS ALSO SLIGHTLY TALLER. IT IS A PERIOD CORRECT FIBERGLASS UNIT THAT FITS LIKE AN "OEM" COWLING. THESE 2 MODIFICATIONS MAKE THE BIKE MUCH MORE ENJOYABLE FOR US NOT 25 YEAR OLDS TO RIDE. THE 2 MODIFICATIONS COULD EASILY BE CHANGED BACK TO FACTORY STOCK. I HAVE EXTRA "OEM" CLAMP-ONS AND COWLINGS.

More from the seller:
THE ENGINE IS STOCK WITH THE ADDITION OF AN AMAZING SET OF 40MM KEIHIN CR FLAT-SLIDE CARBURETORS THAT MAKE THE ENGINE COME ALIVE. ALSO ADDED WAS AN IGNITION ADVANCER. THE ENGINE PERFORMS WITH AMAZING RESPONSE. IT IS IN NEAR PERFECT CONDITION COSMETICALLY AS THE ENGINE PAINT IS ALL ORIGINAL AND WELL PRESERVED.

THE FRAME IS IN AMAZING ORIGINAL CONDITION WITH NO BLEMISHES TO SPEAK OF. THE WHEELS ARE ALL ORIGINAL AND IN AMAZING SHAPE. SHE IS SPORTING A PAIR OF METZLER LASERS. STEEL BRAIDED BRAKE LINES HAVE BEEN ADDED TO IMPROVE BRAKING. THE SEAT IS ORIGINAL WITH NO RIPS AND HAS THE VERY HARD TO FIND SOLO SEAT COWL. THERE IS A SMALL REPAIR ON THE SOLO SEAT COWL. THE BIKE HAS A PERIOD CORRECT D&D EXHAUST IN PERFECT CONDITION. THE INSIDE OF THE TANK IS RUST FREE.

I JUST REBUILT THE CARBS AND SYNCED THEM. INSTALLED A NEW BATTERY, REPLACED THE SPARK PLUGS, OIL AND FILTER, AND FLUSHED NEW BRAKE FLUID THRU. SO THE BIKE IS READY TO BE DISPLAYED OR ENJOY RIDING HER. THE BIKE IS AVAILABLE WITH A RED SEAT INSTEAD OF THE BLUE ONE IF THE BUYER PREFERS. I HAVE A FEW PICTURES SHOWING HOW THAT LOOKS

More from the seller:
THIS BIKE IS SET UP JUST AS MANY OF THE 86-87 GSX-R 1100's WERE BACK IN THE DAY. I HAVE BEEN FIXING, RIDING, RACING, AND RESTORING BIKES SINCE BEFORE GRADUATING FROM AMERICAN MOTORCYCLE INSTITUTE IN DAYTONA BEACH FL. IN 1980. I HAVE 6 OF THESE SO TIME TO PART WITH THE NICEST ONE FIRST.

DON'T MISS OUT ON A VERY SPECIAL PART OF HISTORY THAT WILL APPRECIATE EVERY YEAR.

While the GSX-R750 blazed the trail, the GSX-R1100 followed with subtle changes. The overall dimension of the bike was necessarily bigger. However the aluminum square-section frame was similar (thicker walls and different dimensions in critical areas) during a time when aluminum was space-aged, magical and mysterious stuff. The Full Floater single shock rear suspension was a massive upgrade over twin shock designs, and offered rebound adjustment and an eccentric rising rate linkage. Up front the 41mm forks offered electrically operated anti-dive which was a decided improvement over hydraulic units. Tires on both ends were 18 inchers, the trendy GP 16 inch hoops blessedly a thing of the past. Bodywork was straight off the starting line of an Endurance event, with large, flat side sections and dual headlamps (a massive distinguishing element back then). The four into one exhaust signaled the sporting intent of this machine, as did the triple disk brakes (twin four piston calipers up front, a dual piston caliper out back).

The early GSX-Rs are often referred to as "Slabbies" given the slab-sided nature of the bodywork. They are instantly recognizable and have become tremendously collectible. This particular example shows only 5,100 miles on the clock, and is extremely well kept. Many of these bikes found their way to the race track (these were fantastic club racers, along with the 750), or were thrashed, crashed and sold - repeat cycle as necessary. And while today's bike is not wearing original paint, the paint that is there is attractive and subtle - looking close to a stocker, but with a little extra class. The rare solo seat cover is color matched. There is an upgraded pipe installed as well, making this a period correct and clean Slabbie versus a 100% original and NOS stocker. But that needn't be a negative, as those who ride are more concerned with a clean and functional bike than a collectible garage queen. This is about as clean a Gen I rider that you could hope to find, has a cool history as described by the owner, and is near enough to stock to pass off as a wonderful example of the breed. Check it out here and drool over the pictures. These Gen I bikes are becoming more difficult to find; if you've been looking, it might be time to act. Good Luck!!

2FAST4U: 1989 Suzuki GSX-R1100 for Sale

The seller isn't mincing words here in the listing for this Suzuki GSX-R1100: "This is no poverty sale so low ballers and under 10 feedback stay away... this is too much bike for you."  So apparently if your eBay feedback is low or you like to grind someone for a good deal, a 30 year old motorcycle with 138hp is too much to handle? Good to know. Luckily, I'm not much of a haggler, so I'm sure I'll be fine trying to wrestle this beast through a set of corners.

Of course, rumor is that the K-Model GSX-R1100 was too much for anyone to handle, but not because of the power: handling wasn't the best and both Phil Mellor and Jamie Whitham crashed riding the GSX-R1100K at the Isle of Man TT in 1989, resulting in a ban of big bikes for years afterward. Some people blamed the bike's geometry, some the suspension setup, and many different fixes and parts combinations have been tried to sort out the bike's handling woes, but the bike maintained its reputation as a heavy, ill-handling brute, which ironically has probably helped the bike's mystique, considering similar Yamaha FZR1000s go for much less at the moment.

At 462lbs dry, it wasn't the heaviest GSX-R1100, but it's pretty portly. Personally, I think it's the best-looking version of the big Suzuki, and this iteration of the bike are sometimes known as "Slingshots" in reference to the semi-flat-slide Mikuni carburetors, although I've seen them off the bike and disassembled and I still can't see anything that looks like a slingshot in there.

These days the GSX-R1100's handling shouldn't be a problem, considering the kind of riding the new owner is likely to do on it. The bike has plenty of straight-line speed and stability for weekend blasts, you just want to make sure you plan ahead and don't try to change lines mid-corner. Certainly, it's not lacking in power: the K-Model was powered by the 1127cc version of Suzuki's inline four, still with oil-cooling. That beast of a motor, aside from the styling, is probably the primary reason for buying a "Slingshot" GSX-R1100.

Hiding in Plain Sight – 1986 Suzuki GSX-R750R Limited Edition

"Now why would somebody use this funky bronze paint on this GSX-R ?" you say, not the usual red/black or red/blue/white, but otherwise an -80's GSX-R750.  But this is a not-available-here limited edition in Yoshimura racing colors.  With several factory go-fast goodies, the GSX-R750R conformed to KISS endurance racing principles, taking light weight and reliability to the winners' circle.

1986 Suzuki GSX-R750R Limited Edition for sale on eBay

Suzuki capitalized on their air/oil-cooled experience and the new 749cc engine made 100 hp, hung in an alloy perimeter frame.  Despite having recently introduced the model, they extended the swingarm for 1986 by 25mm to calm the handling.  The Limited Edition features front suspension and brakes from the 1,100 cc model, including an electrically operating anti-dive system.  Other particulars include a monoposto seat and lightweight dry clutch.  18-inch tires are fitted front and rear, ostensibly to ease wheel and brake changes in the pits.

The outstanding condition of the paint on this LE initially had me thinking it was a U.S. model painted by the owner in Yoshimura colors, but apparently the mods are limited to the Öhlins monoshock and Cyclone muffler, along with some slightly oversized decals.  With 22.5K miles, a repaint is almost certainly somewhere in its history, but it is faithful to the original.  Not sure about the gold wheels, looking back shows them most often in white, but they look great.  From the eBay auction:

While I have changed a few things that does not mean you can not change it back. The Yosh stickers are noninvasive and have not damaged the stock paint. Yes, this is factory stock paint that was available in Japan. I installed and recently rebuilt Öhlins shock. The forks are polished and the brake lines are SS braided. I took a risk that, in my opinion paid off, by having the wheels powder coated gold. I wanted the bike to resemble a Yosh race bike from back then. The inside clutch side cover and Yosh covers were painted. The housing for the clutch actuator is NOS. I recently purchased it, removed it from the factory packaging and installed it on this bike. This bike has been gone through very thoroughly and it is ready to ride or store to admire. 

You can only pick two from the fast/reliable/cheap menu, and the GSX-R750R was expensive at the time, a result of low volumes of special parts.  Bidding has reached nearly $10K without nudging the reserve, so this will still be a pricey 750.  Maybe a more period-correct Yoshimura muffler in black could be found, but otherwise this is a pretty together and special example.  Guess you're only allowed two from the golden-age sportbike menu, when the choices are a nice stock presentation, a special model, and a pretty good bargain...

Sharp Slabbie Survivor: 1986 Suzuki GSX-R750 for Sale

Suzuki's GSX-R750 brought endurance racer performance to the masses. It may not have been the first bike to use a full fairing wrapped around lightweight aluminum monoshock frame and a four-cylinder engine, but it was the first bike to make that formula accessible to ordinary mortals, and it popularized the format. Prior to the GSX-R's introduction in 1985, you needed to be looking at something from a boutique manufacturer like Bimota if you wanted that kind of package, and those were far out of financial reach of most enthusiasts.

In a step that seems retrograde at first, the GSX-R used oil cooling instead of water. But this actually meant for a lighter, simpler package that was also easier to work on, meaning the potential loss in maximum power was a good trade off. A high-capacity oil pump and a system of oil jets dubbed SACS or "Suzuki Advanced Cooling System" helped keep things cool and that, along with dual overhead cams and four valves per cylinder, helped the bike produce a genuine 100hp.

This 1986 example would have been from the first year the bike was actually imported to the USA. Slim, right-way-up forks [with anti-dive!], 18" wheels and very skinny tires clearly date the bike, but it otherwise appears pretty shockingly modern, considering it is 32 years old. It does have a few minor blemishes and small cracks in the fairing mounts, but is otherwise about as perfect as you're likely to find outside a museum.

From the original eBay listing: 1986 Suzuki GSX-R750 for Sale

For all those searching for an original, early GSX-R that wasn’t beat to hell or “modified” by some 18 yr old, here it is. All original everything in amazing condition. Miles are correct- no replaced speedo or set back to 0 after rebuild. Previous owner said the tires were original. Some scuffs, scratches and your typical stress cracks around the fairing bolts (as typical with these old Slabbies). Tank is beautiful, dent free and unlined. Exhaust/heat shield is perfect- (probably worth 2k in exhaust and tank alone if you can find them in this condition). A surface scratch approx 4-5” long on right side of tank (probably can be buffed out) and a few mm gouge on decal stripe on right tank side. Have a new tank decal kit if you’re going for museum quality restoration. Small (approx. 1/8”) plastic piece cracked on tail section cover, left side bottom shown in photo 17.  Some clear coat wearing off due to age near headlight cowling decals, photo 13. I tried to show everything, including flaws in the photos. In general, the paint is amazing. I took these photos in bright sunlight so some of the distortion you see is reflection. And I didn’t clean the bike and bathe it in armor-all for the photos. What you see is how it is after taking the cover off after several years. Never saw road salt or cinders- was previously a FL bike. 

I purchased this bike nearly 3 years ago, rode it approx 200 feet after it left the shipping truck, and parked it. Battery was removed and bike hasn’t been run since then. I just noticed some crusty brake fluid buildup that weeped from the front reservoir when taking these photos (4/23/18). Brakes should be bled, fluid replaced. I should have drained the carbs (but didn’t), so they may have to be cleaned.  

I bought a new GSX-R750 in '86, sold it when the military had me for 4 years, and purchased this one for more $ than what I paid new in 86’. If you want one of the nicest examples of the first true street -legal production race bike, and something that will hold its value, here’s your chance. More fun than a 401k too. I’m selling because after hitting the big Five-O mark, I’m more into dirt riding and the race replica style ergonomics don’t agree with my back and neck any more. Sold my Kawi triple, my GS1100, and Yamaha 2 strokes, and this is the last to go. PA antique title in my name. (Last owner was also older,  so bike was never abused).

Photos are part of the description ( **and no, the Shelby Cobra and KTM in the pictures aren’t included). I tried to include all the good and bad. If there’s any questions about things I may have missed, feel free to email and I’ll gladly answer. No outside CONUS shipping unless discussed prior to sale. I won’t crate and ship but I will work with your shipper. Bike located near Wilkes-Barre/Scranton, PA. Have your finances in order: if your bid wins, it’s yours. Non-refundable Pay Pal deposit due after auction. Bike and title won’t be released until all payments clear. Less than 10 positive transactions contact me first before bidding. In person examination can be arranged if desired. No low-ball offers please. Don’t waste my time or yours. I don’t need the cash, so if I can’t get what I’m asking, I’ll just keep it. If you can find one nicer and all original, go for it.  Thanks for looking.

Relisted because I ended it early due to not wanting to sell it the first time. My wife promptly changed my mind.

The asking price? $7,500 which is obviously on the high-side for a Slabbie right now, but not really out of line, considering the condition and originality. It wouldn't be all that hard to find a cheaper one, but minor blemishes aside, this one's in pretty exceptional shape.

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...
