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Sure, the double-cradle frame design was fairly primitive and had been superseded by modern aluminum beam units like Yamaha's Deltabox, and Suzuki's oil-cooled inline four experiment ultimately gave way to the liquid-cooling used by the other superbike manufacturers, but Suzuki made the somewhat outdated package work just fine on both road and track.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.

Slingshot Superbike: 1989 Suzuki GSX-R750 for Sale

Slingshot, engage: Road-worn 1988 Suzuki GSX-R 750

Slingshot Gixxers have gained value over the last couple years on the strength of their reputation as basically the earliest available fully modern street legal sportbike. Short of an astronomically expensive RC30, a late '80s GSX-R is about as close as you'll get to a vintage bike that rides like something from this century. Beyond that, they carry a mystique born of their world-beating pace when new. The awe they inspired when they debuted has evolved into full-on legend status.

1988 Suzuki GSX-R 750 for sale on eBay

With the help of redesigned fairings and suspension, 17-inch rubber and a new rack of flatslide Mikunis, the '88 Gixxer burst on the scene with technology and pace that was unheard of at the time, especially for something so light. Back then, the lack of water cooling didn't raise any eyebrows, though Suzuki did have to get creative with oil cooling to keep the things running properly. The 750cc inline four commanded 112 horses in street trim, and the bodywork had been slickened to reduce the mill's effort.

This 1988 Suzuki GSX-R 750 is in unrestored, original condition, except for some exhaust and airbox mods. Whereas many of these bikes are either hammered or babied, this one strikes a nice balance of looking like a bike that was well looked-after, but ridden as it should have been and stored without huge regard for the cosmetics. If you're looking for a rider and you don't care about looks too much, seek no more. If you're looking for an easy restoration that doesn't require a nut-and-bolt re-work, here's your steed. The seller is quite proud that the bike rides on its original tires, but we'd have those suckers swapped out in a heartbeat.

From the eBay listing:

1988 GSX-R 750 Slingshot. This is a true Survivor, never been touched with the exception of the exhaust. Runs and performs perfectly. I do have the original air box also. Original tires that are in excellent condition for their age. The tires tell the story of this bike, it has been rode less than 500 miles a year. Some of the clear is peeling from decales (normal for the age of the bike). Right fairing has crack by lamp (see pic) and solo seat has small crack in rear, quick fix if you want but, I would leave it alone as bike is a survivor! Hate to see this bike go but, must make room and that is the only reason while it is going up for sale! I will listen to any reasonable offers!
Also bike comes with really nice matching Suzuki jacket cost was $550.00 when bought! Email any question you might have and also see another listing of mine on a 1989 Suzuki GSX-R 1100 that is also up for sale!

At $5,000, the asking price is right at what Hagerty says an excellent example should go for. With fairly low miles, great patina and rising interest in these machines, he might not be too far off.

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.

Teenage Dream: 1991 Suzuki GSX-R1100 for Sale

The 90s sportbike market is booming right now. Folks that grew up riding or lusting after vintage 1960s and even 1970s bikes are steadily aging out of the hobby, and values for bikes of that era are already pretty high. Many people that lusted after 90s bikes, on the other hand, are right in that sweet spot, where they're young enough to still enjoy bikes like today's Suzuki GSX-R1100, but old enough to have some mid-career disposable income, now that the kids are headed off to college... And while the values of 1990s sportbikes have risen sharply, solid examples of some amazingly capable and entertaining machines are still available for much less than your average midlife crisis Corvette.

It also helps that the ergonomics of the big Gixxer, while considered pretty extreme at the time, are a far cry from the ass-up, head-down, seat-like-a-plank superbikes of today. In fact, the riding position could almost be considered "cushy" and far closer to a modern sport-touring machine. While still technically considered sportbikes, I don't think that there were too many classes that would have allowed this later Gixxer to compete when it was new, but that wasn't really the bike's mission statement by the 90s. It was devastatingly effective at the kind of riding your average weekend warrior does, with relatively stable, predictable handling in spite of the near 500lb weight, good wind protection, and room for two-up blasts.

The majority of the package was pretty unremarkable, with an outdated but effective cradle frame, a full-fairing, a monoshock rear, and garish, neon-airbrush graphics. The biggest change from the earlier "Slabbie" and "Slingshot" GSX-Rs was the addition of updated bodywork with improved aerodynamics, including a fully-enclosed headlight unit. But the star of the show was definitely the engine, Suzuki's hulking "oil-boiler" inline four that relied on engine oil, a high-capacity oil pump, and an oversized cooler to keep temperatures under control.

Displacement was up to 1127cc for this M-model version, and the factory claimed 145hp, although much more was available with careful tuning. These are famously tough bikes, and variations of the engine saw use in the later Bandit 1200 and GSX1400. But the writing was on the wall, and looming power and emissions requirements meant the addition of liquid cooling for 1993's iteration of the big GSX-R to help it keep pace with bikes from the other Japanese manufacturers.

Of course, that meant even more weight, and while these things may disguise their weight on the move with a low center of gravity and good suspension, they're incredibly heavy if you're say, rolling one around your garage or a showroom... This example has obviously been cherished, and the seller appears to have been very meticulous when it comes to maintenance.

From the original eBay listing: 1991 Suzuki GSX-R1100 for Sale

I graduated high school in 1991 and this was my dream bike. At the time when I was 17, and was riding around a Riva 180 scooter as I couldn't afford the GSX-R, and I recall them being about $8,500 new. So when I could buy one, I did and looked for the very best stock, impeccable bike I could find just like I saw on the showroom floor. This bike is insanely clean, all original stock parts including the rare factory OEM solo cowl. I went through just about every mechanical thing I could, not because I needed to but because I didn't plan on selling the bike. See pics: I kept all the original replaced OEM parts like o-rings from cabs, needles, jets, o-ring seals, float bowl gaskets, etc. I wanted a bike that ran and looked like brand new and this one checks off both boxes. There was no expanse spared on this bike, period. The bike starts right up with choke, idles, and purrs along. I get told over and over not to sell, it's just a really excellent example of a perfect bike. The bike is truly a time warp.

At 9,469 miles, I went through the bike entirely and correctly as follows:

  • Carburetors. First, all four of the head-to-intake pipe o-ring seals were replaced, head oil hose o-rings, all o-ring seals in the carbs, including the most important o-ring on the plastic slide with emulsion tubes, float bowl gaskets, needles, seat valves, pilot jets, air jets, seals from replaced original seals
  •  Brand new Bridgestone BT016R Pros with 40 miles on them, they still have the knobbies... I went with these because they looked to most original to the bike and have the correct profile. Some tread patterns do not look correct and the profile is off, these look similar to the originals
  • Brand new air filter
  • Brand new oil filter and Motul 5100 10W-40 oil, mineral based
  • All new OEM factory NGK plugs including one factory OEM spark plug cap that was loose
  • All new bearings in the wheels and sprocket carrier. All factory OEM with boxes and receipts [NSK, NTN, etc. No Chinese bearings.]
  • EBC sintered brake pads new front and rear. 40 miles on them
  • Full hydraulic flush of brakes and clutch with Motul 5.1 fluid also at 9,469 miles
  • Recharged the rear shock with nitrogen to 140 lbs
  • New YUASA battery with trickle charger connection
  • Factory toolkit included, along with the original rear passenger grab handle
  • Factory solo cowl included

Bidding is up to near $6,500 with plenty of time left on the auction. These aren't quite as desirable as the earlier models, but all GSX-R1100s are pretty collectible at the moment. Clean, carefully-maintained, low-mileage examples like this are very hard to find, something that's reflected in the shocking jumps in prices we've seen in a very short period of time. They're big, fast, reliable, and relatively comfortable. What's not to like?

Clean, Low-Mileage Slingshot: 1989 Suzuki GSX-R750 for Sale

Suzuki’s GSX-R750 revolutionized the sportbike game by bringing racebike handling and technology to the masses. There were obviously plenty of other sportbikes available at the time, like Honda’s VF1000F and Kawasaki’s GPz900R, but none seemed to capture the style of the era quite as well the Suzuki, with its endurance-racing bodywork and striking blue-and-white graphics. It didn’t hurt that it had the performance to back up the race-bred style.

Interestingly for a cutting-edge sportbike, the original "oil-boiler" GSX-R's engine almost seems like it was a step backwards, as it was not water-cooled. Instead, the GSX-R’s designers took a page out of Colin Chapman’s book, and used an oil and air-cooling system to save both weight and complexity. Luckily, they left out Lotus’ factory-installed mechanical and electrical gremlins… Suzuki’s Advanced Cooling System or “SACS” used a high-capacity oil pump and a large oil-cooler to do the same job as a radiator, and the package made 112hp in the second-generation version seen here.

The second-generation of the GSX-R was introduced in 1988 and affectionately known as the “Slingshot,” owing to the unusual design of the semi-flat slide Mikuni BST36SS carburetors. The Slingshot actually had one less cc than the original bike, because of a more oversquare bore and stroke that resulted in 748cc. The updated engine could rev higher and made more power, but naturally less torque, and increased weight meant some customers weren’t especially happy about the change: the extremely rare homologation GSX-R750RK actually switched back to the original bore and stroke dimensions to restore some of the lost torque at the request of race teams.

The new version kept the oil-cooling though, and the perimeter aluminum frame, along with revised styling, suspension, and 17” wheels that make it look and perform more like a modern motorcycle. I’m not generally a huge fan of Japanese sportbikes, but the second-generation GSX-R750 and 1100 are on my short list of favorite motorcycles. Okay, it’s technically a pretty long list, but this is still a really cool bike.

I don't especially like the heavy four-into-two exhaust system seen here, but it is original and should add to the value for collectors. "Showroom condition" is an overused term and  is often applied to bikes that are very nice, but far from the way they rolled off the dealer floor. It shouldn't be subjective: aftermarket turn signals, exhausts, and even period-correct performance-upgrades technically disqualify a bike. But as a non-expert on Gixxers, this one looks like it might fit the description, or at least come pretty close.

From the original eBay listing: 1989 Suzuki GSX-R750 for Sale

Rare opportunity to obtain an original 89 GSX-R750 in mint condition with original exhausts and components. 

8880 miles from new, runs perfectly and needs nothing

Originally Purchased from local Suzuki Service Manager and collector, maintained in a climate-controlled garage. 

 One small scratch on the rear left tailpiece otherwise in excellent condition throughout.  

Recent tires and battery

No oil or gas leaks whatsoever, no stains, engine is smooth

Buyer responsible for shipping arrangements and costs. 

Please do not bid if you do not intend to purchase.

The curse of the "everyman sportbike" was the very reliability and affordability that made them so ubiquitous: most owners didn't bother to cherish them as they would a more exotic, or maybe more fragile machine, and they were ridden, flogged mercilessly, and discarded when they were worn out or when a new generation was introduced, then "customized" horribly by their second or third owners as the obsolete version became more affordable. These days, clean examples of Suzuki's oil-cooled GSX-Rs are quickly snapped up by collectors. Just a few years ago, you could get one of these for a few grand, but prices are shooting up quickly, especially for nice, low-mileage bikes like this one. Don't scoff too loudly at the $9,500 Buy It Now price, since bidding is already up above $7,000 with plenty of time left on the auction.
