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...

Literally Found in a Barn: 1989 Suzuki GSX-R1100 for Sale

The term "barn find" pretty much says it all: the collectible car or motorcycle in question was found sitting in an actual barn, where the previous owner stored it when it stopped running. Possibly hidden under a layer of dust, old blankets, back issues of Playboy, and mold. The implication is that it is in complete, original condition, but has been somewhat neglected cosmetically and mechanically. The term gets thrown around regularly as a sort of shorthand for "original, low-miles, and in need of restoration," but seems to be exactly the case for this Suzuki GSX-R1100K "Slingshot."

The second generation GSX-R1100's nickname came from the quartet of 38mm semi-flatslide Mikuni "Slingshot" carburetors that fed the dual overhead cam, four-valve, inline four engine. It actually displaced 1127cc, up a bit from the original's 1052cc, but still featured Suzuki's Advanced Cooling System or "SACS" to keep things within optimal temperatures. SACS used a multi-chamber oil pump to effectively cool and circulate the oil, with circuits in the cylinder head and jets directed at the pistons. Later GSX-R1100s adopted a more conventional set up with a radiator and coolant, but here Suzuki stuck with the concept that simpler was better and lighter, although the Big K isn't exactly a flyweight. Mass continued to creep up throughout the 1100's successive generations and the new frame used here was both stiffer and heavier than the one found on the Slabbie. With a dry weight of 462lbs, the "K" version was never going to be particularly agile, so it was more of a GT than an actual sportbike, something that Suzuki tried to rectify the following year when they made changes to the suspension.

Unfortunately, the GSX-R1100K never really matched up with expectations: I have an old issue of SuperBike magazine that describes it as "... quite pretty. To look at, sure, but never to ride." But it's really the beefy engine that defines the GSX-R1100 experience anyway. It was a powerhouse, the Small Block Chevy of the time: endlessly tunable with a wealth of performance parts available. People set them up for drag racing, and even created road-race hybrids by squeezing the 1100 engine into the GSX-R750, which is pretty much the same idea Bimota had when they built their lightweight and extremely quick SB6, although it was a very tight fit in both cases...

Of course, a GSX-R1100 by its very nature isn't necessarily all that uncommon, but ones in this kind of condition are very rare these days: the powerful engine, reasonable ergonomics, and good wind protection meant they got used as intended, racking up huge miles, battle scars, and less-than-tasteful aesthetic "upgrades" popular at the time. People looking to make them into the corner-carvers the looks advertised tried all manner of fixes that worked or didn't in varying degrees, but the end result was very few remain as delivered by Suzuki, and even fewer have covered so few miles. With just 722 miles on the odometer, I doubt you'll find a less used example anywhere outside a museum.

From the original eBay listing: 1989 Suzuki GSX-R1100 for Sale

1989 Suzuki GSXR 1100 perfect condition with 722 miles,  was a barn find been stored since 1991 but not climate control storage literally in a barn. The bike was redone but didn't need much as the miles are so low. The body was completely done to perfect factory spec's no cracks or any problems, the wheels are original but do have a bit of chips,  bike runs great and needs nothing. Full tune tires everything done including carbs. This one for collection beautiful bike and super rare. Also comes with passenger seat parts. Bike will sell no matter what

The seller's opening bit is set at $7,000 which seems pretty fair considering the condition and low miles, but there are no takers yet with very little time left on the auction. It's a shame the pictures aren't better lit, since I think this is the very best-looking version of the long-running GSX-R series, especially in classic Suzuki blue-and-white. If you're looking to actually ride it, I'd expect there are plenty of shops out there who can recommend suspension changes to make a Slingshot handle, probably using off-the-shelf Suzuki components, along with brake upgrades and weight saving measures. At the very least, you can probably swap the original 2-into-2 exhaust for a 4-into-1 and save 20 pounds. But honestly, the original bike offered plenty of stability, even if it lacked agility, and this one should probably be enjoyed for what it is: a freeway blaster par excellence or a great two-up weekend rider. Given the low mileage though, I'd bet it might end up stored away in a collection somewhere.

Number One: Prototype 1986 Suzuki GSX-R1100 for Sale

Although displacement was technically a bit more than a liter, the first generation Suzuki GSX-R1100 really established the modern literbike formula: take a big inline four engine, and squeeze it into a 600 or 750 sized package. The philosophy that created the iconic Gixxer was initially tried out with Suzuki’s GSXR400, and the result was so good they applied the same lightweight methodology to a 750cc machine, and the GSX-R750 was born in 1985, with the 1100cc version following in 1986. Frames of the 750 and 1100cc versions aren’t identical, but are pretty similar, with the 1100 using thicker square-section aluminum tubing to increase rigidity and handle the extra power of the larger engine.

The 1100 engine actually displaced 1052cc and shared its SACS oil-cooling system with the 750cc version: in both cases, Suzuki avoided the additional weight and complexity that water-cooling would bring by using air and oil to keep the twin-cam, four-valve engine within appropriate operating temperatures. But the high-performance engine needed some additional help to keep from exploding, so the Suzuki Advanced Cooling System used a complex oil pump to circulate oil, lubricate bearings, cool the heads, and even featured oil jets directed at the bottom of the pistons. With 137hp on tap, the big Slabbie was a bit of a monster, as it had just 489lbs dry to push around. That’s obviously not hugely impressive today, but keep in mind that the bike’s 75lb-ft of torque isn’t all that far off a modern superbike and meant that the big Gixxer could pull like a freight train.

The 1100 wasn’t exactly agile, but it did handle well for the time on its 18” wheels with tires that are laughably skinny by today’s standards. The 1100 featured a set of sophisticated anti-dive forks and Suzuki’s Full-Floater linkage rear suspension kept the power in check, while providing a less punishing ride than was typical of hard-core sportbikes of the era. A modern-ish brake set up with a catchy Deca-Piston name slowed things down for the next bend: a pair of four-piston calipers up front mated to a twin piston item in the rear meant ten whole speed-retarding pistons were on hand to keep you from crashing into a hedge when the world turned twisty after you got a bit too liberal with your right hand. It all added up to a bike that was a little on the heavy side, but one that offered good stability and world-class power, a wildly fast GT with Japanese reliability. Obviously, companies like Bimota used the same elements to create their lightweight road weapons prior to the introduction of the GSX-R, but Suzuki took that basic formula, added a dash of reliability, and brought it to the masses.

From the original eBay listing: 1986 Suzuki GSX-R1100 for Sale

Obviously the posted asking price is a silly one, but we are open to all offers that respect this motorcycles exceptional condition as well as its rarety and we will not scoff at anyones idea of what its value should, would or could be in todays international bike collectors market place

Suzuki GSX-R1100 No. 1 Details

This mid 1985 build / 1986 first registered Suzuki GSXR-1100 was one of the centerpieces of our small private collection and is one of just a handfull of bikes left from said collection which we have been dissolving this past year, mostly due to age and health related reasons and because we are consolidating all our personal items and scaling back from multiple locations to just one place to live and because we are giving up our motorcycle hobby alltogether

This is not a 'normal' motorcycle in 'average' condition so the text describing it and this sale's particulars might be somewhat different than what one would normally see in a listing here on Ebay. Please go to our Seller Feedback Rating to see what previous buyers have consistently been saying about us in the past 17 years in regards to every single item we have sold here on Ebay

The first GSXR 1100 was a groundbraking motorcycle in more ways than one, it started the era of large displacement, light weight Superbikes in the mid-80-ies

Being able to own an original, genuine, verifiable with factory documentation, unrestored Vin-1/Engine-1 vehicle of any type, make or model has got to be at the top of most collectors list of must-have‘s.

The vehicle being a top displacement model from one of the major motorcycle manufacturers should make it even more desirable

Details:

Mid-1985 build earliest prototype Suzuki GSX-R1100 in existence

Was the secret 'Star' in our small personal bike collection for many years

Verifiably a genuine Serial No.1 and Engine No.1 motorcycle. One of a small number of GSX-R1100-eds build by hand in the factory to set up the subsquent 1986 assembly line production run. This motorcycle was build with a handmade, prototype frame, on a prototype frame jig and it contains many one-off features and components.

Details on request in person would be best; to list just a few major ones:

This GU74 series bike has the early prototype exhaust without the toe-heatshield, it also has the early version clutch cover without any oil-amount stamped in the specific location where all other bikes have the cc amount stamped in

It has the correct, prototype-only all metal footpegs for rider and passenger since the rubber/metal type was not yet ready for use. It has all the original bodywork pieces mounted, in the original factory paintjob.

Some of the panels have some lines and colors that do not really match and line up correctly and do not match any other painted-alike original bike of the same type.

There are many more differences and details on this special bike,

too much to list them all here in this basic description

A correct and proper title exists for this motorcycle as does its original November 1985 first print Din-A5 owners manual.

Also present is the correct, original and super rare 4-language, first edition spareparts manual, printed in Dezember of 1985 in which this specific motorcycle’s exact Vin Number is listed as the starting Vin for the entire series of GSXR 1100 bikes for the next 3 year production run.

Four original sales brochures including the first edition english market version with print date of December 1985 are included in the memorabilia folder. The original keys, 4 correct A27 dark tinted turnsignals, the original toolkit with the rare Suzuki air gauge in its pouch, used for fork pressure and tires and the original GSX-R prototype factory display stand for motorcycle shows complete this offering.

We have owned this motorcycle for many years and have done a lot of research into the history of these early prototype GSX-R 1100-eds (the GSX-R750 also had some early prototypes build in the factory in Japan, none of which we have ever seen come up for sale in the past 15 years)

We have never seen any prototype GSXR-1100 for sale, they were not supposed to be sold to the public, being used mostly for press events, cycle shows and as photo models for the many different manuals and brochures. They were also being returned to the factory after they had been used for all these events and most of them were destroyed

Rumors of an early prototype 1100 existing in the UK in a private collection have so far not been confirmed. In any case, the bike offered here for sale is one of a kind, completely original, never repainted, never restored, exceptionally well kept up mechanically as well as cosmetically and should deserve a place in a serious motorcycle collection or possibly a private museum of some sort. It was ridden extensively in its 33 years, but always cared for and babied to keep it in this exceptional condition

We have prepared an online photo album showing this motorcycle in detail in more than 100 high quality images that might be of interest to a serious collector.

The seller mentions the "silly asking price" and $250,000 [yes, you read that correctly] is certainly silly for anything short of TE Lawrence's Brough Superior or a MotoGP bike in rideable condition with a truckload of spares. But they're just putting that out there, and are open to offers. Which is a good thing because, as cool as this is, I doubt it's worth anything near $250,000. Obviously, a rare bike is worth whatever someone is willing to pay for it, but I get the feeling that only a very particular sort of collector will want to pony up, since although it's rarer, it's also a little bit cruder, from the seller's description. The question is: what is it worth? Well, nice original "slabbie" GSX-Rs sell for around $7,000 or so, with only the GSX-R750 LEs really getting much higher. This one could obviously worth much more, being a prototype machine and the very first registered example of a bike that pretty much defined the modern superbike. I'll be curious to see where it ends up.

Slab-Sided Collectible: 1986 Suzuki GSX-R750 Limited for Sale

It's hard to imagine that, just a couple years before the introduction of the GSX-R750, Suzuki's top-performing repli-racer was the stylish, but very last-generation GS1000S, a bike with twin shocks, handlebars, a center-stand, and a bar-mounted bikini fairing. The original "Slabbie" GSX-R750 that came along in 1985 brought modern endurance-racing style to the masses and codified the formula laid out by much rarer and more exotic machines like the Bimota SB2. This particular GSX-R750 Limited Edition claws back some exotic cachet from the Italian brand, and is one of just 299 imported to the USA to meet AMA homologation requirements.

The heart of the GSX-R was an oil and air-cooled inline four with dual overhead cams and four valves per cylinder. It lacked liquid-cooling in a bid to save weight, reduce complexity, and improve reliability, but still had a few high-tech tricks up its sleeve: Suzuki’s Advanced Cooling System or "SACS" featured a double-chambered oil pump was designed to more efficiently circulate and cool the bike’s lubricant, along with oil jets that sprayed the bottom of the pistons. The aluminum frame used a mono-shock rear and four-piston brake calipers clamped triple discs. The Limited version added a very trick dry clutch, lightweight solo seat tail section, and the GSX-R1100's electronic anti-dive forks.

The Limited was differentiated by the striking red, white, and blue paint seen here on the distinctive, slab-sided bodywork, compared to the standard white-and-blue or red-and-black available on the regular GSX-R. When new, the bike was the most expensive Japanese sportbike, and was priced at $6,500, a shocking $2,000 more than the standard model. Performance advantages were very minimal but that wasn't really the point and this is, to my mind, the best-looking version of the early GSX-R.

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

Race homologation special. It has 4545 miles. This bike is in as near perfect collectors condition for a 31 year old bike. Motorcycle was just fully serviced (ie carbs were serviced; all fluids changed; new tires added, as originals showed signs of cracking.)

These bikes have surged in price, exceeding $20K in most cases.

If you are looking at this bike, you know what it is, so NO LOW BALL OFFERS!!!!

The seller is correct that prices have surged, and his bike appears to be in excellent, very original condition that includes a stock exhaust that could be either "cool and retro" or "shockingly ugly" depending on your predilection for slotted heat shields. Certainly it's of value to collectors. Unfortunately, while his $20,000 asking price is fair, it actually seems just a bit on the high-side, at least looking at Limited Editions we've featured here on RSBFS in the past. I'm not sure just how far off his asking price an offer would have to be before it qualifies as "a low ball offer," but I have a feeling he may be disappointed. Will at least one buyer meet his asking price? It's very possible: those same recent bikes I mentioned didn't quite get to $20,000 but were very close.
