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.

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.

JDM Gixxer: 1986 Suzuki GSX-R750 Limited Edition

Honda's famed RC30 was basically designed from the ground up for competition, and seemingly only sold to the public to satisfy production-based racing requirements. That's one way to go about it, but if you don't have Honda's practically endless resources, how do you create a machine that will help your racers to compete at the top levels of production-based racing? You build something like this Suzuki GSX-R750 Limited Edition. In recent years, "Limited Edition" has come to refer to things like luxury trim packages for Toyota Corollas, somewhat watering down the cachet of the term. But in this case, it was truth in advertising, with just a few hundred made to satisfy the regulations.

The regular GSX-R was already a pretty impressive machine and, considering that the Limited Edition was the most expensive Japanese sportbike of 1986, you'd be forgiven for thinking that the performance of this rare and exotic version is underwhelming. But the changes were designed to allow their inclusion on race machines, not make for a better roadbike. The LE was just six pounds lighter than the standard bike, most likely a result of the fiberglass solo-seat tail section. Power was very similar as well, since the engine internals were virtually identical to the stock GSX-R750, and flat-slide carburetors are great for producing maximum power, but they're not really suited to everyday use. Fortunately, the LE's lightweight vented dry clutch should produce enough rattle to drown out the supposedly noisy carburetor slides... Aside from those notable and very expensive upgrades, the bike also featured a revised swingarm for improved stability and the electronic, anti-dive forks from the GSX-R1100, although I wonder if many race teams actually used those. Photos of our recent GSX-R AMA Superbike suggest that at least some of them did...

So out of the box it didn't necessarily perform any better than a stock bike, and was hideously expensive. But honestly, most manufacturers of homologation specials probably weren't too concerned about selling them: I'm pretty sure the rules only required that they build the required machines, so if they sat in showrooms for a few years, manufacturers wouldn't lose any sleep over it. Collectors and enthusiasts with the money to buy them still did so, regardless of cost, but the main goal was to get the right parts legalized for the racers.

1986 GSXR-750 Limited Edition in Japanese Domestic Model Specification
Suzuki only produced 500 units world wide of the GSXR750 Limited Edition

The bike is imported from Japan.
Not registered yet in the U.S.
This bike is sold without title. (NO TITLE)

The last Limited Edition GSX-R750 we featured on the site was also a Japanese import in similar colors that were intended to celebrate Suzuki's success at the 8 Hours of Suzuka, but this appears to be a different bike entirely. First-generation "Slabbie" Gixxers are already increasing in value, and nice Limited Editions are starting to command premium dollars. The lack of a title could prove to be a hassle, but many people considering a purchase will be looking to collect or display, not actually ride it, so that may not be all that much a problem. The $13,800 asking price seems in line with recent LE prices, but I wonder if the lack of title will have any impact on its value.

Classic Racer in a Box: Ex-Doug Polen Suzuki GSX-R750 for Sale

Looking for a fun weekend project to keep you busy for a while? Well look no further than this ex-Doug Polen Suzuki GSX-R750 racebike. It's not exactly finished, but all of the really important parts appear to be there to get you started... Strangely enough, it seems like the AMA racebikes used many of the stock Suzuki components, even switching from the more exotic dry clutch to the standard wet unit, according to the seller. So that should help, right?

The introduction of the Suzuki GSX-R750 in 1985 was a seminal event in the history of motorcycling. It may not have been the first or only bike to use fully-enclosed, endurance-racer styling wrapped around a bulletproof, large-displacement inline four and monoshock aluminum frame, but it made that formula affordable and available to the masses, and led directly to the sportbikes we know and love. Later sportbikes would add liquid-cooling to the equation to help generate maximum power, but the Gixxer eschewed such frippery as too heavy for their pure speed machine: in spite of the visible cooling fins, it's oil that does most of the work. The oil-cooled powerplant utilized their SACS or "Suzuki Advanced Cooling System" that used a double-chambered pump and oil jets directed at the underside of the pistons to keep temperatures under control. Other than oil cooling, it followed modern designs and used dual overhead cams and four valves per cylinder.

Obviously, as a race-spec machine for the street, the GSX-R750 spent plenty of time competing in various classes both abroad and here in the US. This particular bike was used in AMA racing and was ridden by Doug Polen. Polen was a world-class rider who got his start in AMA racing but left to compete in the World Superbike Championship, where he won the title on the trot in 1991 and 1992. He continued to compete in both international and American roadracing with success, netted a win at the Suzuka 8 Hour endurance race, and even dabbled in MotoGP.

There's additional information about the bike, its history, and the included photos over on eBay, so head over and take a look.

From the original eBay listing: Ex-Doug Polen Suzuki GSX-R750 AMA Superbike for Sale

I have researched the photo archives of Cycle World and Cycle magazines and obtained a number of unpublished photos from their records.  I've also bought photographs from freelance photographers that covered AMA racing in that year.  Special thanks to Larry Lawrence, of The Rider Files website.  I will provide these photos to the buyer with the proviso that they remain unpublished.

Each rider had two chassis.  The chassis and motors evolved constantly through the season and Doug probably got the good parts first, as he did better than Otter in the results, starting with the first race.  Their A bikes had all of the good parts at each race and the B bikes had more stock components.  You can clearly see in the photographs the progression of modifications during the season for all of the bikes and the lower spec of the B bikes.

The chassis is un-braced, with modified stock forks, Kosman Triple clamps, Kosman brake discs, AP calipers, a Fox shock and Marvic magnesium wheels.  The swingarm has been slotted, to allow for more variation in wheelbase.  Jim Lindemann worked with them on the shock valving, although he passed away a few years ago.  I have spoken to an ex-Fox engineer and he'd be happy to restore the shock but the records they had of those years were destroyed a few years ago.  Sandy Kosman now lives in Portland Oregon and the last time I talked to him, he was willing to get the discs reground on a Blanchard grinder, if desired.   One of the previous owners began the restoration years ago and the chassis, as pictured, is where he was when he sold the bike to the next owner.

The bodywork used was stock Suzuki plastic.  Early in the season it was raced in 1986 blue/white Suzuki colors; later in the season some of it was sporting the 1987 blue/white Suzuki stock colors.  A perforated metal filler panel was incorporated into the lower fairing V and the lower fairing panels had holes cut in them to allow for more ground clearance.

The motors were modified during the season and varied quite a bit.  They had Yoshimura (either kit Suzuki or Cosworth) pistons, different crank bearings, heads ported by Ron Scrima, Megacycle cams with Yosh retainers, a Tsubaki cam chain tensioner, and various carbs and exhausts.  At one point they obtained dry clutches and close ratio transmission gears but went back to running wet clutches and stock transmission ratios.  They may have run an ECU with a higher rev limit.  Ron Scrima passed away in 2011 but his company (Racing Engine Service) is still in business in Texas and the current owner was with Ron for about 25 years, so they might be my first choice for an engine refresh.  Another option would be Kelly Roberts, also in Texas.  I have never disassembled the motor, so I do not know what internal components are present.

I am interested in selling this project to someone that has the necessary resources and desire to restore it to an as-raced condition and to preserve it for the future.  It is a significant bike, as it was one of the highest placed privateer AMA superbike efforts of that era and was ridden by the rider that probably had more success in the USA racing the first generation Suzuki GSX-R than any other rider.  I would be willing to discuss this bike in more detail, via telephone, with any serious prospective buyers.  I am also willing to provide additional photos, a more complete listing of what components will come with the bike, and an approximate idea of what additional components will be needed to complete the restoration.

I have listed the mileage as 99999, as eBay requires that the mileage be listed for any vehicle sale.  The true mileage is unknown, as it was never recorded, which is not unusual for a race bike.

It also looks like the bike went through several iterations, giving you a bit of flexibility in terms of the color scheme you choose. If it were complete and in as-raced condition, this would probably be a very valuable motorcycle. As it stands, it's a valuable... basket case. How valuable? Well the But It Now price for this bit of American roadracing history is $4,950. This is going to need a lot of love, time, and money to finish, but I think this GSX-R deserves to be restored to its former functional glory.

Rare Slabbie: 1986 Suzuki GSX-R 750R Limited Edition for Sale

Update 3.28.2017: Previously seen in October 2016, this GSX-R Limited is back on eBay with a starting bid of $13,500. Links updated. Good luck to buyers and seller, -dc.

1986-suzuki-gsx-r750r-le-r-front

It’s interesting how some bikes seem to come up for sale in waves, like owners who've had their bikes for years see similar bikes up for sale and think, “Hey, I’d better get in on that before demand is all gone!” Or maybe it has to do with the ages of the bikes and the related ages of the owners… Regardless, we’ve seen a number of Suzuki GSX-R750 Limited Editions come up for sale recently, in a range of conditions, but this example appears to be very clean and original.

1986-suzuki-gsx-r750r-le-l-front

The original GSX-R750 was a pretty significant bike when it was introduced in 1985, and it became an icon for good reason: the fully-faired styling, aluminum-frame, and monoshock suspension helped to define the modern sportbike, and was adopted by millions of hooligans and squids as their bike of choice. Plus, they do look pretty sharp in Suzuki’s traditional blue-and-white paint.

1986-suzuki-gsx-r750r-le-cockpit

The GSX-R750 was powered by an oil and air-cooled inline four to save weight and reduce complexity compared to water-cooling, although it did use dual overhead cams and featured four valves per cylinder. The temperatures generated were kept in check by Suzuki’s Advanced Cooling System or "SACS" that featured a double-chambered oil pump to more effectively circulate and cool the bike’s lubricant, along with oil jets that sprayed the undersides of the pistons. In spite of the obvious cooling fins cast into the engine, it’s actually oil that does most of the cooling in the Gixxer.

1986-suzuki-gsx-r750r-le-engine-detail

Based on the regular GSX-R that was introduced in 1985, the Limited Edition was intended to homologate specific parts for superbike and endurance racing, Suzuki’s equivalent of the Yamaha OW01. Parts exclusive to the LE were the vented dry clutch [clearly visible in the above picture] and electronic anti-dive forks that contrasted with Honda’s mechanically-operated forks. The seat unit offered no passenger accommodations, as befitted the bike’s race-bred styling.

From the original eBay listing: 1986 Suzuki GSX-R 750R Limited Edition for Sale

The bike is an amazing piece of history, absolutely gorgeous and has been in my collection for some time. However I am feeling my mortality and so it is time to pass it on to a new owner. I have rode this bike sparingly over the past years but have maintained it both mechanically and cosmetically in a temperature controlled environment. Cosmetically, the bike is in excellent condition for a 30 year old bike, with the exception of a very, very small soft dimple in the right hand upper rear corner of the tank that a good PDR tank man could take care of but in my neck of the woods there are none. (had to place light to see it) All original equipment to best of my knowledge, but will let you be the judge. I understand in terms of a collector bike originality is important. I noticed the exhaust pipe was not right after purchase, the heat shield louvres were horizontal rather vertical as they should be ...and spent a tidy sum to make it right.

Mechanically the bike is “spot on” (just tuned) but you may want to do some fine tuning as well as set the bike up to accommodate you personally, or simple admire for what it is, and will be in the future. One fork seal starting to slightly weep, and if you planning on riding I would suggest new tires as these are getting on in years.

I am not going into the history or the desirability of this particular model. It is generally well known by any student of the early superbikes that maybe interested in this bike. And if not there is considerable available on-line or from knowledgeable resources. Also for some, what it is, and is not as far as originality will be a subject of debate, I personally do not regard myself as a expert so I have attempted to display the bike in the best way I can by removing the plastics. Someone willing to pay what I am asking at least deserves to have the opportunity to evaluate the bike in the proper manner. All in all, I personally feel it a very nice example in comparison to the limited number eBay sales I have monitored in the past.

1986-suzuki-gsx-r750r-le-front-wheel

Just 299 examples were imported in 1986, making this one rare Suzuki. This example has a few minor nicks and chips, but looks very clean and complete, with bidding up north of $11,000 and the reserve not met. There are several days left on the auction and active interest, which should come as no surprise, considering a recent, very non-original example sold for over $19,000!

Slingshot My Heart: 1988 Suzuki GSX-R750 for Sale

Suzuki's original GSX-R750 is arguably one of the most influential sportbikes of all time. Other bikes may have incorporated some of its design and performance elements, but none were able to combine them all into such an affordable package, or were able to capture the public's imagination in the same way. Every iteration of the Gixxer was made by the bucketload, but the bike's reliability and ubiquity meant that they were used and abused, and then discarded, making pristine examples like this one both desirable and very hard to come by. The early "Slabbie" has already reached collector status,  but the second-generation "Slingshot" GSX-R750 models are steadily increasing in value as well and offer more modern performance and handling, compared to the slightly vintage original.

Looking at the slab-sided design, it's pretty easy to see where the Slabbie GSX-R got its nickname, but the Slingshot is named for the 38mm semi-flatslide Mikuni "Slingshot" carburetors that fed the 748cc inline four cylinder engine. Suzuki's original GSX-R was designed with simplicity and light weight in mind and, as a result, the bike was oil instead of water-cooled. But the significant cooling demands of a high-performance sportbike meant the Gixxer needed a sophisticated, high-capacity oil pump and associated cooling and filtration system known as Suzuki Advanced Cooling System or "SACS" to keep temperatures under control. SACS was used on the GSX-R750 and 1100 up until 1992 when Suzuki bowed to convention and switched to water cooling for subsequent generations of the bike.

This particular example appears to be in excellent condition and has obviously been enthusiast-owned and lovingly maintained. It isn't just some well-maintained survivor though: it includes some very tasty modifications like that Metmachex swingarm, a very desirable bit and the suspension has been more than just "overhauled," as the original bike didn't have upside-down forks until 1991. The LED signals are probably not to everyone's taste, but they're reliable, improve visibility, and are, as the seller mentions, easily changed.

 

From the original eBay listing: 1988 Suzuki GSX-R750 for Sale

You are bidding on a 1988 Suzuki GSXR-750 first year, 2nd Gen. model GSXR-J aka Slingshot in Suzuki's traditional blue & white paint scheme that is very sought after. This is one of the lightest and fastest oil cooled GSXR of its time. This particular bike is mostly original condition with the exception of a few upgrades which I'll list later on in the description. Some of the OEM parts  I still have (I'll notate) and can be sold with the bike, if you are interested in going back to stock.

The exhaust is a Yoshimura pipe ceramic coated and aluminium canister. The Mikuni 36mm flat slide carburetors has a Stage 3 jet kit, these both were ideal performance mods for this motor. The blinkers have been replaced with modern LEDs but you can easily go back to stock since all the wiring and connectors are intact. Also, the windscreen was switched out to a tinted by the previous owner. The suspension has had a major upgraded since the stock GSX-R were notoriously known to have a low ground clearance with only a slim margin of error. Both the front and rear have been completely rebuilt by Lindemann Engineering. The rear swingarm is ultra-rare Metmachex (equal to JMC) braced and with eccentric adjusters. This is the style of the endurance racers used back in the late 80's since the stock was shown to have flex. I do have the original OEM swing arm available upon request. The original speedo and tach have been replaced due to the needles falling off. I replaced them with an 1100 model of that year since it's was close to the miles but I do have the original for the new owner and I am basing the miles on the original speedo/tach cluster.  
 
All of the body panels are original and in good condition, no cracks or brittle spots. There are some scratches from general wear and tear which I'll try and capture in the photos. The wheels are in great shape, paint is excellent and no sizable chips. Cosmetically, I would claim this motorcycle is an 8 out of 10.  Mechanically it is flawless, runs perfect, shifts smooth, pulls hard and easy to ride. All of the electrics work as they should; blinkers, horn, lights, speedo, tach, are properly functioning. The bike just had a full detailed service and tune up, all fluids were flushed, and mechanically everything was inspected and replaced if necessary. The Battery and tires are less than a year old.  

This GSX-R750 was well-taken care of and adult own, and I am the 3rd owner. It was never abused or down to my knowledge.  Please feel free to ask any questions, do not hesitate to contact me. If you need any additional pictures or have any additional questions,  feel free to message me or call me here 424-225-2028. Also, I'm including with the sale, are the OEM passenger seat, and tank bra. Service manual and receipts for all maintenance and upgrades.

There is plenty of time left on this auction, but bidding is already pretty active. This particular version of the GSX-R was only produced for a couple of years and doesn't seem to have been particularly well-regarded when it was new but, with all due respect to the original "Slabbie" I think it's far and away the best-looking GSX-R ever made and if I had space in my garage, I'd really want to find a nice one.

Featured Listing: 1986 Suzuki GSX-R750 for Sale

Update 1.18.2017: Sold in 11 days! Congratulations to buyer and seller! If you have an outstanding Rare Sportbike for sale, email us about a $59 Featured Listing for exposure like this this GSX-R 750 received! -dc

Today's Featured Listing is the grandaddy of modern sportbiking, the Suzuki GSX-R750. Sure, you could probably argue that other bikes like Kawasaki's GPz or pretty much every Bimota were also significant, but Suzuki's original "Gixxer" had all of the pieces in place: a fully-faired, bug-eyed endurance-racer aesthetic to match the performance available from the inline four and the lightweight, aluminum-framed monoshock chassis to put that power to the ground. Bimota may have perfected the formula, but Suzuki made it affordable to the masses and, in the process, created an icon. Obviously, boatloads of these were made, but boatloads were also crashed and thrashed and neglected, meaning these have suddenly become very collectible and not easy to find in this kind of condition.

Introduced in 1985, the first-generation bikes like this one are sometimes known as "Slabbies" due to the large, slab-sided fairings. Early bikes eschewed liquid-cooling for their 750cc inline four in favor of a high-capacity oil system known as SACS: Suzuki Advanced Cooling System. The system used a sophisticated oil pump to direct jets of oil at critical components and was used up until 1992, when the GSX-R received more modern liquid-cooling. Why SACS? It was felt that the addition of a radiator and associated plumbing would add unnecessary and undesirable weight and complexity to the new sportbike. Colin Chapman would have been proud, although he probably would also have drilled a bunch of holes into that aluminum frame...

The bike arrived in the US in 1986 and was virtually identical to the 1985 model, excepting some updates to lighting, slightly revised bodywork, and a longer swingarm for improved handling. This particular example looks very clean and appears ready to ride, with fresh plugs and tires!

From the seller: 1986 Suzuki GSX-R750 for Sale

One owner, expertly maintained, synthetic oil used entire life, never been crashed, garaged all its life, all original parts with the following upgrades: Progressive fork springs, Works rear mono shock, advanced ignition rotor, K & N filter and front braided metal brake lines. Old parts are available along with a Suzuki shop manual. Bike has new Metzler Z-rated tires, Iridium spark plugs and a one-year-old AGM battery. 

With almost 60,000 miles on the bike, it is mechanically top notch; the plastic does show some wear with three minor cracks that have been repaired and stop-drilled. Close-up photos are available. The tank and frame are flawless. Most of the plastic is in great condition. Regular oil/filter changes have been made at 5,000 to 6,000 miles or once a year when not ridden often. Brake and clutch fluids were regularly changed, and fork oil was changed every five years. The valves have been recently adjusted. Other than new fork seals--replaced twice--there have been no mechanical failures in the bike's history.

The bike is in excellent mechanical condition with 60,000 miles on it. Cosmetically the bike is in original and very good condition. I am asking $5,800.00 for it. The bike is currently in Ventura County, CA. The bike, while a collectible, is regularly ridden. It runs and handles great!

 

With some pretty outrageously-priced Slabbies out there, the $5,800 this seller is asking seems very reasonable. The miles are pretty high but, as with most collector vehicles, condition is far more important, and this example appears to have been very sympathetically owned. Upgrades are practical and, in my mind very appropriate. Few compromises are needed to own this classic sportbike: no basic maintenance that requires engine-out servicing and no unobtainable parts or esoteric knowledge are required, making these pretty practical collectibles, assuming you find a good one. In fact, probably the biggest limitation will be finding modern rubber for those skinny, 18" hoops.
