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.

Suzuki Saturday – 1988 Suzuki GSX-R750

1988 brought the first comprehensive update to the 750 Gixxer, with a revised frame and shorter stroke engine, "slingshot" carburetors and 17-inch wheels.  A little heavier than the introductory GSX-R, the 1988 was still lighter than the competition and had the more rigid chassis and additional power to improve overall performance.   Looking very original and excellent for its 22K miles, this GSX-R750 has had some nice mechanical care as well.

1988 Suzuki GSX-R750 for sale on eBay

 

In the engine re-design, Suzuki took 4mm from the stroke and added 3 to the bore, more oversquare and with lower reciprocating losses than before.  Peak power and torque are at 11,000 rpm, while the redline is at 13,000.  The high-volume SACS oil cooling system was also heavily revised, with larger, less restrictive tubing, and a 4-into-2 exhaust was required to limit muffler size.  Brakes and forks are built for the era, and dual headlight fairing has fresh air intakes running back to the airbox.

 

The Illinois owner of this GSX-R has preserved the cosmetics, and actively maintained the running gear.  Suspension has been updated in the rear, rebuilt in the front, brakes improved, and engine maintenance is up to date.  From the eBay auction:

This gorgeous GSX-R is completely stock except for tasteful/safety modifications, including:
-New Pirelli Rosso II tires
-Galfer steel brake lines, front and rear pads
-Penske rear shock
-New EBC clutch and springs
-Forks are serviced, new oil, new seals
-Swing arm and link have new bearings and seals
-New oil and filter
-New wheel bearings
-Valves adjusted
-All electrical components work as they should

 

The GSX-R750 reviewed as a quick-handling powerhouse, with serious racebike ergonomics, and very nearly beat the company's own 1100 to the 1/4-mile traps.  A nicely resolved update to a ground breaking design.  This particular GSX-R is a win-win, great factory cosmetics and all maintenance issues addressed...

Not often seen on RSBFS outside of low-mile introductory-year models or factory racers, the GSX-R750 is the legend that launched a million amateur race teams.  As any long runner, the model has had its great and meh years, and this is an interesting one - 1992 was the last year of the air/oil-cooled GSXR.  The rest-of-world folks got a water-cooler that year, but the U.S. got a final year of the proprietary SACS two-stage oil cooling but new looks.  This lightly used example has been returned to former glory at a Gulf Coast Florida shop, and is ready for a show and / or ride.

After a 1990 engine and suspension update, the GSX-R750 revisions were light for 1992 and the "M" got a new valve train design using a rocker arm for each valve and supplied 115 hp.  Great handling from the alloy frame, 41mm inverted forks, and Full-Floater monoshock rear remained, fully adjustable for those with set-up knowledge.  Stoppage was excellent with 4-piston 310mm front brakes and 280mm rear.  The roomy new fairing was more aerodynamic as well as more comfortable.

With only 5,700 miles this Suzuki was a find, but the fuel system and cosmetics had taken the brunt of the twenty-plus years of downtime.  The owner describes the uncompromising way they were addressed:

When I got it didn't need a thing. Well me being me I couldn't just leave it alone so I started with the fuel system ) just as a precaution ( and knowing old fuel systems real well ) I didn't want to wait until it failed so I ordered four new OEM rebuild kits and complete fuel shut off , all new fuel lines for the shut off as well.

Also the ones that connect each carburetor, all new from Suzuki, ( NO ) aftermarket parts were used.  I did clean the tank with Yamaha tank clean.  Having said that it didn't get to the very top so the lip of the tank still has some left over dust from rust but only on the lip the rest of the tank seems ok .

It looks rusty on the inside but that's just how that product works.  I fitted the bike with new Pirelli Diablo's front and rear I also kept the old tires ,OEM I think, ( I'm not riding on tires from the 90's .

So that lasted about three months and I thought this bike would look its best if I had it painted the factory 1991 colors.

I called the best painter the sport bike world has ever known and asked if he could fit it into his schedule. He agreed, so me being me the colors had to be as close to a perfect match as possible. I also wanted every decal to be as exact as possible so he made all the decals himself. In the end the paint is better than new using only the best paint and materials.

The wheels I had powder coated to match. Then fitted with new seals and bearings, again all OEM Suzuki. This bike didn't have a scratch on it when I got it and it still doesn't. All other parts are original to the bike.

The owner also offers a Photobucket slideshow with some before, during, and after pictures here.

The idea of rebuilding and tuning four carburetors has likely scared off many would-be classic sportbike riders, but a pro has taken care of that here.  As well the paintwork, looking super and original, when so many are scarred up or rattle-canned.  Starting with an undamaged low-mile supersport from the last year without a coolant system, this owner has been careful to return to the stock looks and retain all the smaller parts.  This adds to the value now and as time goes on.  The owner asks $6,000 and Steve at Southwest Cycle can be reached at (239) 898-3050.

Big Boy Toy – 1989 Suzuki GSX-R1100

Though the reasons for hiding away a top-of-the-line sportbike may be a head-scratcher, it's a thrill to come upon the bike you lusted over back in the day - stock and barely used.  This 1127cc K-variant has just 4,400 miles, stealth paint scheme, and spent all its nights in a Queens garage.

With a newly developed air-oil cooled engine shoehorned into the slightly modified frame from last year's 750 model, the GSX-R1100 was poised to be the big Kahuna in 1989.  The 138 hp package had a two-stage oil pump to ensure reliability, called the Suzuki Advanced Cooling System.  The high-hipped aluminum frame was beefed up and had 43mm Kayaba cartridge forks in front, with Full Floater monoshock rear, both fully adjustable.  Brakes were Suzuki's own 310mm fronts with 4-piston calipers, and 240mm rear.

Appearing to be a one or maybe two-owner machine, this Gixxer has been preserved in its 1995 road condition.  From the eBay auction:

Up for your consideration is a 1989 GSXR1100.  I feel the condition of this bike is way above average for the year and miles (4400 miles). The originality speaks volumes as to who owned it and how it was treated.  The bike was bought by me as a collector bike and never put on the street. It has been keep in my climate controlled garage for the past several years. Since most of these bikes have been crashed and repainted you would be hard pressed to fine another in the condition of mine . The only modification is the vance & hines exhaust which was installed at the dealer when new .  This bike still wears its original michelin tires which i have included a picture of the date code. Please keep in mind that this is a 27 year old motorcycle  that has been off the road since 1995 and will need normal maintenance if you have intentions of riding it. I won't say anymore about that as I will let the pictures of the bike speak for themselves. If you have any questions or would like to make a reasonable offer please email me your # and  the best time to call .  All sales are final , no warranty and sold as is where is.

Though pre-season reviews were excellent, production GSX-R1100 K's acquired a suspect reputation for handling, and with the bulletproof powerplant, many were lengthened into dragsters - street and strip.  Luckily this one hasn't been under the knife, and the suspension could be dialed in for the new owner.  A carburetor rejuvenation is probably in the cards after all this time, and certainly new rubber.  Though it would be great to see this monochrome endurance fairing steam past, this GSXR might have a future on display...

Beautifully Restored 1986 Suzuki GSXR-1100

1986 Suzuki GSXR-1100 on eBay

GSXR1100_rightside

Often overlooked by collectors focused on it's 750cc little brother, the 1986 Suzuki GSXR-1100 is just as important in the evolution of superbikes.  Suzuki started the GSXR family on the other end of the spectrum, with their 400cc model while gradually working all the way up to the 1100cc masher that we see here.  Even by today's standards, the performance numbers are impressive.  Powered by an air-cooled 1052cc mill producing a claimed 137hp and weighing just 434lbs, the competition was left in the dust.  The biggest problem was that the square tubed aluminum from was susceptible to distortion from the big power and the braking and handling of the era wasn't really up to the task either.... but that's half of the fun, right?

GSXR1100_leftside

This example is probably the nicest one I have seen since my very early riding days and it's almost impossible to believe that's it's showing 80,000km on the clocks.  Much of bike is original, but a few bits have had some well deserving love.  The seller's eBay ad is very detailed and can be read here: 1986 Suzuki GSXR-1100 on eBay

1986 Suzuki GSXR 1100. First year original restored condition. Full service history from day 1. Full Yoshimira exhaust circa 1989. Original exhaust in perfect condition come with the bike as well. Fully tuned for pipes with dyno at 114hp at rear wheel. All new OEM switch gear purchased direct from Suzuki while they still carried it. New screen in original box. Never installed it because I used the bike and didn't want to get it dirty! New rotors, chain, chain guard, tires almost new. Has period correct Corbin touring seat circa 1980s but original seat and passenger seat cowl in fantastic condition included with bike. Paint is original in near perfect condition. Don't be fooled by mileage. Entire top end redone with recent valve adjustment.

Did I mention that it's clean?
