Long Way Home – 1986 Suzuki GSX-R750R

Even in the midst of a riding rejuvenation, plans and priorities can change.  Here’s a 1986 GSX-R that’s getting quite close to bike night, just needing a new owner’s shove over the goal line.

1986 Suzuki GSX-R750R for sale on eBay

For its U.S. debut, the GSX-R got a 25mm longer swingarm, calming the handling from 1985.  Around the bike, lightness was a focus, and performance guided designers.  The oil-cooled engine saved the weight of a water system, and got larger valves in part by using smaller spark plugs.  Wheelies caused by the 100 hp launch could be reversed by a stoppie using the four-piston front brakes.   The flat-sided fairing had an endurance racer’s simplicity, but it was the last hurrah for the track-oriented 18-inch wheels.

This owner has been slowly returning his 750R to a more stock condition, but left a few things for the next custodian to weigh in on.  It looks very presentable, even at the office, and could have some incremental re-finishing without tearing it down.  Comments from the eBay auction: 

Bike runs, shifts and idles as it should.
All lights, signals and horn work as they should. Left signal dash light bulb is out.

These bikes are getting harder and harder to find. Hasn’t been cut up or crazy modifications. Some body panels have been repaired and repainted. Tank is in very good condition other then a few scratches on right side of tank (See in picture posted). Tank looks to be all original paint. Plastic body panels do have some imperfections here and there.

Wheels have been repainted white by previous owner. Not a very good a paint job on wheels. Wheels were and should be black to be correct.
I believe I have a left and right new oem G graphics decal that goes on lower part of cowl in black area. Just haven’t put them on yet. As long as I can find them. They will go with the bike as well.

No rust in tank ever. Very clean.
Bike would need a restoration to be perfect .
This is in excellent running, driving and or take to local bike shows.

Tires that are currently on the bike are out of date. Would need to be replaced to be safe. I bought a set of brand new tires for it that will go with the bike.
Brand new oem tool kit included.
New battery last summer. Always left on tender.
After market Yoshimura slip on. Sounds great. I don’t have the oem exhaust.
Front fork seals will need to be replaced .
Body work is oem but some panels have been repaired.
Oem air box goes with the bike. These are getting hard to find with all the brackets and hoses.
This bike has a bunch of new oem parts through out the bike.

I had the valves and carbs adjusted last summer. Bike runs great. Front calipers were also rebuilt and new pads installed last year. Brand new oem Suzuki main wiring harness installed last year. New Oem head light housing, adjustment springs and hardware. New head light Oem wiring harness. Brand new oem foam gauge pad installed last year.

First year icons will either be hardly or heavily used, and this one has some miles but looks to have spent the last several seasons with more tinkering than riding.  Without being a Special Edition or RR, this could still be a great example.  Hopefully the reserve doesn’t put it too far out of the almost-there-project department.

Why Not the Best ? – 1994 Yamaha YZF-750SP with 3,251 Miles !

While a WSBK title wasn’t in the cards, Yamaha’s 750cc FZR built on the OW-01’s designs and homologated newer ideas for next year.  If you see one it will likely be a gray import, but this rare SP has an MPH speedo and is in sparkling condition.

1994 Yamaha YZF-750SP for sale on eBay

Yamaha packed a lot of tech into the new FZR-750, with 5-valve heads, 11.5-to-1 compression, and the EXUP exhaust management resulting in 125 hp – hard to beat in a 750.  The SP had updated cams, 39mm Keihin flat-slide carburetors, and a close ratio gearbox the superbike racers needed.  Suspension on the SP was fully adjustable and somewhat stiffer, plus it shared the scary-good 6-piston 320mm brakes with the R.  The SP only came in a monoposto, and the seat subframe was quickly replaceable. 

Seeming to be ready for its next display spot, this SP is surprisingly free of even shelf wear.  A good deal of work awaits a riding collector, but it certainly looks worth the effort.  From the eBay auction:

Very rare , and collectible 1994 YZF 750SP.  Bike is mint, museum quality with all the factory warning label stickers still on it.  Only 20 of the SP version were ever brought to North America.

Heaps of competition from the other big three in those days, though the YZF did well in endurance racing, and the quality build helped many privateers riding affordable machinery in the later 1990’s.  This one has seen none of that, and hardly looks to have even done the miles on the odometer.  The ask has me wanting to title the post Fund Factor, but maybe a reader can propose an offer and we’ll keep our fingers crossed.

Performance Kit – 1984 Bimota SB4S

Early on, Bimota sold kits to incorporate the buyer’s own drivetrain into their chassis and fairing designs.  This unicorn was professionally prepared and has only seen the light of day for 1,800 miles since.

1984 Bimota SB4S for sale on eBay

Bimota specified the 1075cc air-cooled engine from the GSX-1100, and shares its formidable 112 hp.  Rimini made their own four-into-two exhaust, and of course their chromoly semi-cradle chassis, with billet aluminum sideplates.  Components are a history lesson of their own, with Ceriani forks and DeCarbon monoshock.  Looking bigger in the 16-inch wheels, brakes are all 280mm disks, with four-piston calipers up front.  Lightweight fiberglass is stretched over the hippy package, baring only the three-piece alloy wheels.

Showing clean but maybe not museum storage, this SB4S appears original right down to the tires, and complete.  The GSX engine was evidently blueprinted before sliding it into the Bimota kit.  A slick detail and maybe re-finish the front fender and it might look more like the rarity it is.  Comments from the eBay auction:

This bike is super rare, with only 100 or so of the S versions with the full fairing being made. The other 200 or so SB4 models had a 2/3 fairing that did not go under the engine.

This is one of the last (Chromoly) steel framed Bimota made before going to aluminum frames. It is also one of the last kit bikes they sold. This particular bike was ordered and assembled by The Performance Works of Canoga Park, CA. The original build sheet is included with the bike. Details include:
  • Brand new Suzuki GS1100 engine as a starting point
  • Yoshimura pistons, 2mm oversize
  • Vance & Hines clutch basket
  • Welded crank
  • Heavy duty cam chain
  • Carb work
  • Only 1,800 miles!

This bike has just been serviced with new Mobil 1 oil change, OEM oil filter, NGK plugs, and a new battery. It fires right up and sounds great.

Along with the original build sheet, there is the factory sales flyer and a copy of the parts list for the entire bike. The VIN for this bike is SB400127 (#127 out of the 300 or so SB4 and SB4S total bikes built).

So close I could be there in a half hour, but ’tis no longer the season for a test ride.  No worries about getting out of the air stream, any rider under six feet will be stretched out on the tank just to reach the clip-ons.  Geared tall and set up for higher speeds, wide open two-lane would be a lot more fun than errands around town.  Not that this collectible is liable to see a whole lot more of either.

Lucky Luc – 1994 Yamaha YZF-750SP

Yamaha continued developing and racing the YZF750 after the hallowed OW-01 with good results, even though the -SP homologation special never made it here with a motor vehicle title, they showed up as race machines on a bill of sale.  This street registered Canadian example has around 25,000 miles but a newly rebuilt engine.

1994 Yamaha YZF750SP ( Quebec ) for sale on eBay

With revised cams and 39mm flat slide carburetors, Yamaha’s 749cc Genesis engine delivered 125 hp, great for the era.  The alloy chassis sports a monoposto alloy seat console, and fully adjustable suspension.  320mm brakes came with 6-piston calipers and reviewed as magical.  “Torn paper” graphics were all the rage and look complete despite a note in the listing.

Just a few pictures will require investigation, but it does look worthy of the time.  With Canadian registry, the owner had the engine done in suburban Montreal, but maybe the Vermont location suggests free delivery to our northern border.  Normally an owner would be advised against refreshing and engine just before a sale, but that makes it intriguing.  Comments from the eBay auction:

Yamaha YZF750sp 1994.

This is the only ONE registered in Canada.

Engine refreshed by Luc Lapièrre from Moto RL in Saint-Jude Quebec.

The motor has less than 1,000 km on it. (600 miles)

The bike has 40,000km and it is all ORIGINAL. (25,000 miles)

Testers gigged the SP for a balky powerband and turn-in that needed a firm hand.  Remembering that this bike was intended for private race teams to acquire and modify to the limits of the rules, it makes more sense.  Engines would be blueprinted to accommodate what the carbs were feeding, and race-tuning the suspension and slick tires made it handle as intended.  But carefully set up for the road ( and with evident engine work ) this one might be all you could ask in a mid-size superbike.

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.

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…

Endurance Racer: 1982 Honda CB1100R for Sale

Update 7.24.2017: Interested parties can email the seller directly: mrcbx@att.net

Built in small quantities between 1981 and 1983 and very rare sight here in the US, the Honda CB1100R was created to homologate the big, four-cylinder machine for endurance racing. Based on the CB900F and powered by a 1062cc air-cooled inline engine, it featured the usual raft of upgrades to engine internals, frame, and suspension to make those parts eligible for competition. Unlike the CB900F, the engine was mounted rigidly in the frame to act as a stressed-member, improving handling at the expense of additional vibration.

Power was rated at 115hp and the bike weighted in at 520lbs dry, which may sound heavy in a modern context but meant the CB1100R was on par with period rivals. The bike was fast and very stable, and Honda’s first use of dual-piston brakes up front with vented discs meant stopping power was considered excellent at the time. There were TRAC anti-dive forks up front with adjustable units at the rear. Gold ComStar wheels are stiff and light, but a pain to rebuild if yours are damaged and a composite fairing means replacements for broken parts could be very expensive…

These don’t come up for sale very often, especially here in the USA where they were never officially available. So how small were the “small quantities” produced? 1,050 were built for 1981, with 1,500 for 1982 and another 1,500 for 1983. That may not be Bimota levels of exclusivity, but this is still one rare motorcycle, especially for a Honda. Values will only be going up on bikes of the era and I expect that all those affordable 1980s bikes you can generally find on eBay will soon be a thing of the past.

From the original eBay listing: 1982 Honda CB1100R for Sale

This is a nicely preserved CB1100RC.  If you are looking at this ad, then you should know what this is.  One of only about 1500 bikes produced by Honda to be able to compete in the pro-am series races in Europe and Australia.  Unique and incredibly rare in the USA. There is not even a 1982 RC at Barber Motorcycle museum, there is only a 1983 RD…

I have gone through this bike to make sure all is functional, it is still an exciting bike to ride even 35 years after it was made!  It is on recent Michelin tires, and everything works as it should. This bike has some personalized period-correct modifications, the original exhaust has been replaced by a Cowley 4 into 1 system, some of the parts on the bike have been polished and chromed, but it shows very well and is mostly original.  It was imported into the US by Larry Conlin, who sadly passed away a couple of years ago; at that time it had not been running for some time, and it did not have a US title.  Since then it has been properly imported, and recommissioned for use.  I have copies of the original UK paperwork, the VIN is correct for a 1982 CB1100RC, so this is the real thing!

The bike can be heard running in this clip provided by the seller. So what is something like this worth? In other markets, they sell in the neighborhood of $20,000 but I’m not sure if it can command the same price here in the US. Currently, bidding is up to just a shade north of $12,000 with a couple days left on the auction.
