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...

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.

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!

In a World – 1990 Suzuki GSX-R750 Racebike

Toward the end of the air/oil-cooled era, Suzuki took one last stab at a higher torque engine, with lightness helping the pistons and rods survive the 13,000 rpm redline.  Set up for racing with a newly built engine and suspension updates, this GSX-R750 appears ready to take it to the track.

The "long stroke" 749cc still quite oversquare, the GSX-R750 had a wider torque band than than previous model and accessed 115 hp.  Four 38mm Mikuni carburettors handle fuel delivery.  Everywhere but America the legacy perimeter frame held 41mm upside-down forks, but these have been updated to those from a 1994 model.  Brakes are dual 310mm disks with 280 mm rear.  The race fairing is a pretty good silhouette of the factory bodywork, with no lights or pillion.

Presented by an Arizona parts manufacturer, this race bike looks newly commissioned and super clean.  The large Hagon decals are puzzling with the claimed RaceTech forks and Öhlins monoshock, but it wouldn't be the first time a sponsor appeared only on the outside.  From the eBay auction:

1990 Suzuki GSX-R750. Was built in 2016 for AHRMA next generation superbike racing. The motor was rebuilt with new rods, pistons, valve springs. Has 1994 forks, all Race Tech parts. Ohlins rear shock, Mikuni 38 flat side carbs, and much more.

One of the first 750's into the 10-second 1/4-mile bracket, the 1990 machine was also a serious handler requiring an authoritative rider.  Historics can be some of the most fun race weekends ever, with the competition in a long perspective, and the focus on the hardware.  With the inherent simplicity of air/oil cooling, this GSX-R can show them how it was done.

2nd Generation – 1989 Suzuki GSX-R750

Coming off 1988's major re-vamp, the GSX-R750 for 1989 had the new frame, upgraded engine with slingshot carbs, revised fairing from the previous year along with a couple of tweaks to improve cornering clearance.  Would that it were an R or RK, but the base K model was a great ride, and could be very quick if suspension set-up was done individually.

20160608 1989 suzuki gsx-r750 front

Sporting the SACS ( Suzuki Advanced Cooling System ), the 748 cc motor uses a two-stage oil pump with oil routed past the combustion chambers and piston squirters to help maintain its composure as 13,000 rpm and 112 hp quickly approach.  36mm Mikuni flat-slide carburetors are helped by a shorter intake path, fed by ports beside the headlights.  The perimeter frame is welded up extrusions and forgings of aluminum, as is the swingarm.  Right side up cartridge forks are without anti-dive but adjustable for preload and rebound damping, as is the Full-Floater monoshock.  Stainless 4-1-2 exhaust is new for this year, though this bike has been fitted with a D&D 4-into-1 system.  Brakes are Nissin 310 mm fronts with four-piston calipers, with 230 mm rear.  Steering damper on the left frame is standard.  Though available set up for a passenger, this GSXR has the matching monoposto seat fairing.

Offered by a New Jersey dealer, this GSX-R750 looks excellent or better and claims only 1,407 miles.  Sharper eyes may see mods but I'm not.  None of the body faux pas look like accident damage.  From the eBay auction:

Incredible find.  1989 GSXR 750K, its an ICONIC sport bike and becoming highly collectible.  Its not only incredible that this bike still exists but its in really great condition too.  

Bike is ready to ride with fresh oil/Filter, brake flush, New Tires.
 
Bike comes with factory (VERY RARE) solo seat cover with bump pad and also included is the stock seat cover/tailight surround.
 
I have tried to detail most of the defects in the paint but certainly can not get them all so i concentrated on the most obvious ones.  I have not noticed any cracks at all in the body, even all the small tabs seem to be intact.  The wind screen is a bit marked up and most of the scratches can be polished out but I opted to put an original windscreen on the bike verses a flimsy cheap aftermarket one.

Though a production machine and not a rarity at the time, a road registered original like this is not seen often.  Claiming a substantial horsepower advantage over its competition, the factory made some ride-height adjustments and re-shaped the exhaust collector for 1989, resulting in a sharp handling powerhouse.  Since summer is here, any number of aftermarket windshields would serve the purpose while you polish the original or search out a new-old-stock part...

Smaller, But Still Sharp: 1999 Suzuki GSX400S Katana for Sale

1999 Suzuki Katana 400 R Side Front

Introduced in Europe in 1981, the Suzuki GSX1100S “Katana” and its littler siblings like this rare, apparently very late-production GSX400S stunned the motorcycle buying public. A quick glance at bikes available from other manufacturers at the time shows us deep in the era of the Universal Japanese Motorcycle, and the Big Four were clearly following, not leading, when it came to styling. The angular design of the Katana's tank, a tiny quarter-fairing, that compact dash with nearly overlapping gauges, the strange, squared-off seat… it was almost enough to distract you from the fact that the bike was basically a restyled GS1100.

1999 Suzuki Katana 400 L Side

The mechanical components were very conventional: twin-shock rear suspension and the... um, familiar air/oil-cooled inline four cylinder backed by a five-speed gearbox, along with a 19” front and 17” rear wheel combination. The GSX-R that followed updated the mechanicals to match Suzuki’s radical styling but, at the time, those GS bits were deemed sufficient. And they were: the bike handled well enough and proved to be very popular. It wasn’t cutting-edge technology, but the GS was already a solid performer and that engine is powerful, reliable, and can be made to really perform with a wealth of hop-up parts and a vast resource of tuning knowledge pulled from decades of drag and road-racing experience.

1999 Suzuki Katana 400 Dash

Interestingly, the US actually got a smaller, 998cc engine for their “GSX1000S” when it arrived in 1982 to squeak under the 1025cc limit for Superbike racing, but it’s still a big, burly performer. But this little Katana throws that all out the window. I’m assuming the bike was intended for the Japanese home market and I'd expect the engine is basically shared with the 400 Bandit. There’s nothing wrong with the little Bandit, but the Katana’s small-block Chevy quality and a good deal of the bike’s brutally simplistic charm is gone.

1999 Suzuki Katana 400 Engine

From the original eBay listing: 1999 Suzki GSX400S Katana for Sale

Located in Santa Ana, California. This bike has 2273 KM = 1363 Miles. This is a true low KM original bike. The carbs were cleaned about 10 months ago. They do need a light cleaning now because the bike has been sitting. This bike is being sold with a bill of sale only. I don't have a title for the bike and can not get one, so don't ask. More info is available on our website. If you overseas or Canadian buyer, you will have to make your own shipping arrangements. I can help USA buyers with the shipping, or you can arrange your own shipper. Bike is being sold as is, no returns. Ask questions and look at the pictures carefully before you bid. Again, this bike is being sold with a bill of sale only, NO TITLE. 

1999 Suzuki Katana 400 FR

Aside from some wear on the seat fabric, the bike does look very clean and in good shape. So this little Katana is certainly rare, especially here in the US, but does that make it especially valuable? The seller is looking for an $8,000 starting bid and the bike doesn't come with a title, not a surprise but a bit of a problem for anyone who wants to do more than display the it, unless they live in a state with a very permissive DMV. The Katana does make a pretty great display piece, and are seeing an increase in value. They’re striking and very practical, with good parts availability, decent handling, and some pretty big power available from that lump of an engine. But considering that a good 998cc Katana would likely run you less than what this seller is hoping to get, will look almost identical, and be much faster, I think the novelty actually works against it here.
