Ready to Rumble – 1996 Yamaha YZF-750R

Update 11.2.2021: Last see in August of 2020 from the same seller, this one is back on eBay with a buy-it-now of $7,150. -dc

For a while in the 1990’s, sponsorship from Marlboro led Yamaha down a red-liveried path, and the torn paper graphics on this 1996 YZF-750R makes reference without saying it too loud.  It’s a low-mileage example with a recent major service, and looks smashing.

1996 Yamaha YZF-750R for sale on eBay

Yamaha took the successes of their late -80’s World Superbike mounts and ran them by production engineering, preserving as much of the good stuff while bringing the cost out of the stratosphere.  Kept was the forward canted inline Genesis, with the EXUP exhaust tuning system – in road trim worth 125hp.  The aluminum Deltabox chassis evolved with re-designed frame connectors.  New brakes were 320mm disks with 6-piston calipers.  The fox-eye headlights look a little less drop-dead serious than those on the OW-01, but the painted pillion cover passes for a single-seater under way.

The seller’s other auctions seem to indicate a dealer rather than motorcyclist owner, but either way, this YZF is in special shape for its age.  Hard to find fault with the presentation, except maybe to pine for an SP homologation special.  The last service call made everything ready for the new owner.  From the eBay auction:

The YZF750R sold better across the pond than here, but trailed the 916 and CBR900RR and gave way to the R1 in 1998.  The race version did well in endurance events where Yamaha’s quality shown.  This one is right on the edge of too nice to ride too much, but the classic mid-size package and recent maintenance call for at least an occasional back road afternoon.

Almost Pre-Sports – 1985 Yamaha FZ750 with 1,586 Miles !

Though big red dominated, Yamaha’s FZ750R / OU45 regularly appeared as the best of the rest in mid-eighties AMA Superbike.  Here’s a collector which has somehow escaped the suburban Dallas heat, and dodged a lifetime’s worth of garage elves.

1985 Yamaha FZ-750 for sale on eBay

Yamaha had reportedly toyed with as many as seven valves per cylinder, but settled on five for the Genesis engine.  Laid forward to straighten the path through the 34mm Mikuni’s, 105 hp was the result.  The four was wedged across a double cradle chassis, with right side up forks and a monocross rear.  270mm brakes are period correct but seem undersized for the mission, and the 16/18-inch wheel stagger would be seen as under and over-sized just a few years later.  Riding position was a pretty good tuck and helped the rider get behind the upper-only fairing.

The comments say the bike has been in the back of the garage for a generation, so this might be the original owner.  Condition is hard to believe with none of the usual bumps, bruises, or mods that might be expected.  A fork brace is visible and a Fox shock is hidden.  Otherwise it looks original right down to the tires.  Notes from the eBay auction:

This bike has been in a controlled environment for the past 35 years. The 80’s motorcycle market is getting hot and this is a perfect opportunity for a collector or lover to own an iconic bike. It runs and rides like a new bike with a couple of original 80’s upgrades remote adjustable rear Fox Shock and a fork brace. The miles are original, I was putting it in my collection but it needs to be ridden and because of my age and old racing injuries I can’t manage the low bars. The value will only increase as this is the only FZ 750 I have seen come on the market over the last 2 years. One sold in January of 2019 for $9,000 with 39,000 miles on it and needed attention. This bike is as good as the day it came off the ship.

Part of the design concept was the five smaller valves which didn’t require double valve springs, allowing higher revs and an easier life for the cams.  Yamaha stuck with the Genesis for several years, attesting to the idea’s success.  The conventional auction ( high reserve though ) reflects the almost super-stardom of these early superbikes.  It might take a re-list, but interest in an FZ in this condition will come.

Up a Notch – 1992 Yamaha FZR1000

As much of an upstart as the original FZR1000 was in 1987, later design revisions took the superbike to the next level.  Today’s FZR is an elegant survivor with just under 13,000 miles.

1992 Yamaha FZR1000 for sale on eBay

Yamaha’s 1,002 cc Genesis had 5 valves per cylinder from the start, a great technical achievement until the EXUP power valve ( and 10 hp ! ) were added in 1989.  Because of the stretched power band, it’s ok with a 5-speed transmission.  The alloy DeltaBox chassis got revisions in 1989 and again in 1991, with the addition of upside-down Kayaba forks.  320mm brakes had plenty of oomph and reviewed with good feel via the 4-piston calipers.  Clip-ons under the triple clamp are routine in the sportbike world but not so much in the liter category, they draw the rider over the tank and make the fairing’s protection more easily accessible.

Evidently hidden away in a suburban Iowa garage for some of its life, this FZR appears excellent with just a Vance & Hines exhaust and smoked windscreen as visible mods.  Comments from the eBay auction:

Here is an excellent example of one of the legendary sportbikes from the 80’s and 90’s. This bike is in above average condition with minimal chips and scratches. Well cared for with only 12,900 miles. This bike has been kept up on maintenance and needs nothing other than a rider, or stow it away in your collection. These bikes are becoming more and more valuable and extremely hard to find in this condition. 

In 1991 a further redesign of the FZR resulted in the release of the FZR1000RU EXUP, upside-down telescoping forks were fitted and the front fairing was fitted with a single headlight, generally regarded to be the definitive FZR1000 which this bike is.  This bike has a few tasteful mods – Vance & Hines SS2R exhaust that gives it that superbike sound, and a lightly tinted windscreen.

Yamaha got it very right with the FZR1000, to the point that Cycle World named it the bike of the decade, and it even beat the FZR600 around the technical Streets of Willow road course.  Lighter than expected at just over 500 lbs., when 145 hp were applied and balanced on 60-series tires, it became a nimble projectile.

Naked Reprise – 2006 Yamaha FZ-1

While the original FZ-1 was one Cycle World’s bikes of the year, Yamaha made a substantive update for 2006.  With miles in the 1,000-per-year neighborhood, this Tennessee example looks excellent.

2006 Yamaha FZ-1 for sale on eBay

Yamaha brought their aluminum casting technology to bear on the new FZ-1 chassis, cradling the R1-derived liter, and steadying it during its 147 hp moments.  The 20-valve four had a heavier crankshaft than the R1, along with torquier cams and a smoother balance shaft.  Fuel injection is electronic, but this FZ-1 pre-dates any power nannies.  Brakes are up to the task with 320mm disks and four piston calipers.  43mm forks separate compression and rebound damping duties, and are fitted with an almost straight across the top handlebar.  In a close-up the angular fairing could be mistaken for a superbike part.

Despite a little sticker-mania, the owner has taken nice care of their FZ-1,  looking excellent with no particular damage.  Interested bidders will have to ask, since there aren’t enough pictures and not much history in the comments from the eBay auction:

Condition is Used. This bike is in perfect condition. No scratches or dents. Looks like it came off the showroom floor. It has been taken excellent care of and is ready to ride. Clear clean title.

The FZ-1 caught both far ends of the R-1 spectrum, riders who weren’t ready for a superbike statement, or maybe could no longer deal with the R-1’s ergonomics.  The performance put most nakeds to bed, with Yamaha tech and build quality.  The ask seems at the top of the range, but maybe the Make Offer button will make an appearance in a re-listing.

Sporty Single – 1999 MZ Skorpion 660 Sport Cup

A rare sight in-person but almost a regular for RSBFS readers, the MZ Skorpion was a post-East German single 660 with a Yamaha-derived 5-valve head.  This example in Kawi-esque livery may have been owned by a dealer, who has offered other MZ’s and allowed this one only 7,000 miles.

1999 MZ Skorpion 660 Sport Cup for sale on eBay

 

Actually drafted by Norton designers Seymour-Powell, the Skorp had a tubular perimeter frame with Italian brakes and suspension.  Licensed from Yamaha, the thumper nearly made the magic 100 hp per liter, and the smaller engine block kept weight under control at just over 400 lbs. fully fueled.  Clip-ons are sensibly above the triple tree.  The straightforward handling made believers out of may skeptics.

 

Presented by a Rhody-based vintage Jaguar parts house, this Skorpion has what might be the factory’s only two-tone paint.  Cosmetics are excellent and it has been nicely prepared for the next owner.  Comments from the eBay auction:

This bike has under 7K miles on it, has recently been serviced, new oil, filter, plug, carburetor and filter cleaned, new battery, new Michelin tires, aftermarket exhaust.
The bike has not been crashed or damaged and needs nothing. Have title, owner’s manual, original tool kit and some maintenance records.

 

Often seen as the base for a singles track bike, this MZ might be too nice to put the knife to.  Maybe it can be the “before” picture for the racer.  Or could be the most unusual cheap sportbike, maybe the most economical rare sports machine…

Urban Camo – 1994 Yamaha YZF750R

Descendant of Yamaha’s OW01 homologation special, the YZF-750R was a vaunted endurance racer in race trim, and a two-time Bike of the Year winner in the mid-90’s.  A victim of the displacement arms race and an aging platform, the Yamaha 750 lasted only a few years.  This YZF might be a little rough around the edges but has great potential.

1994 Yamaha YZF750R for sale on eBay

The five-valve Genesis head was used on the YZF-750R, pushing 125 hp, with the EXUP exhaust valve helping broaden the curve for the 59 ft-lbs. torque.  The quick-handling chassis was complemented by 41mm upside-down forks and slowed with six-piston calipers over 320mm disks.  Full bodywork has an aggressive stance and room for a co-rider.

Resident of sunny California, this YZF appears to be complete, with mandatory rear fender-ectomy, turn signal change and smaller muffler.  Pictures need more resolution but this bike may be Öhlins equipped, and only minor scuffs are apparent.  From the eBay auction:

29,000 miles
carbs recently rebuilt, may need to be adjusted
starts and runs

a few other items of interest:
MSRP of $10,500 back in 1994.
inverted forks
6 piston calipers
26,000 mile valve adjustment intervals
Genesis 5 valve head
1995 bike of the year for SportRider
1994 bike of the year for Cycle World
only real contender against the Ducati 916 in those years

The Yamaha had a great combination of handling, power, torque, and brakes, and a number are seen with significant miles.  Build quality was second only to Honda and got demerits for just the 432 lbs. dry weight and notchy transmission.  Though better photos and history would help a serious bidder, it’s a no reserve auction and might be right for a knowledgeable fan of the model…

One Year Wonder – 1987 Yamaha FZ700

1987 brought a trade tariff for motorcycles over 700cc, and Yamaha’s response was to de-stroke their recently designed FZ750 to 697cc’s. Though it had the Genesis 5-valve head, some sporting aspirations were value-engineered out. Still, it was an able street performer and is now very rare.

Carrying some interesting design points from the 1985 FZ750, the 700’s straight four is canted well forward to 45 degrees, with the four Mikunis pointed up, and a substantial portion of the fuel load moved down and behind the airbox.  This arrangement paid the steel twin-spar center of gravity benefits as well.  38mm forks and rear monoshock were budget conscious, brakes as well with 267mm disks in triplicate.  The fairing is lightly updated from 1985 and provides good protection and great looks.

20161118-1987-yamaha-fz700-right-front-wheel

With photos showing just under 10K miles, the Iowa owner states the current mileage is just under 13,000, hoping there’s little difference between the before and after pictures.  It boasts progressive fork springs and braided brake lines but it’s otherwise stock.  From the eBay auction:

Very nice used 1987 Yamaha FZ700 in very good condition. Does show some wear, scuffs, scratches here and there, otherwise looks very good. Gets a lot of looks and good comments from people. It starts well, runs well, shifts and brakes very well. The front suspension has been upgraded with progressive springs. It has stainless steel brake lines front and rear. This is a bike you can start it up and ride for hundreds of miles with out any problem.

20161118-1987-yamaha-fz700-right-rear-wheel

Though Yamaha was in between very sporty periods with the FZ’s, the 700 had plenty of giddayup for an 11-1/2 second quarter and road-if-not-track-worthy handling.  Classic showroom management with the FZR baiting the eventual FZ sales.  Might be just the low pressure entrée into a classic sportbike…

Proof of Concept – 1990 Yamaha OW 01

Shortly after the Superbike World Championship opened in 1988, manufacturers were compelled to prove their production bikes were up to the task, by providing comparable bikes to the marketplace.  Numbers of bikes homologated depended on the size of the manufacturer.  Though it did not result in a championship, Yamaha provided the OW 01 to the fray in 1989 and 1990, and in the process created a very memorable street machine.

Built to compete with the YB4 and RC30, and the eventual championship winning Ducati 851, the OW 01 was a thinly disguised racer.  A 749cc carburetted straight four delivering over 120hp can hardly be otherwise.  The 5-valve OW 01 was reputed to be quite rideable, thanks to EXUP, the automatic exhaust port valve.  The aluminum perimeter frame was not an innovation but this lightweight DeltaBox was , with similar fabricated swingarm.  Large for the day, 43mm forks are fully adjustable, as is the Ohlins rear shock.  Braking handled by 280mm front disks and 177mm rear.

Not without its blemishes, this OW 01 looks good for its 34,000 kms.  From the eBay auction:

One of only 500 produced this bike has never been raced. dry stored for the last 7 years, running and riding perfect before storage
has the stock exhaust and muffler which is in mint condition,
has 34,000 kilometers (20,000miles)
top end was done using yamaha parts and i have the receipts
comes with the owners manual and pouch
original toolkit, missing one small socket
as you can see in the pics there are 2 chips in the paint beside the headlight and under the headlight area there are stress cracks in the paint.

A higher mileage OW 01, this machine might be a restoration candidate, maybe after some serious rides.  The steep price when introduced speaks volumes about the development dollars and potential in each machine.  OW 01’s are available as perfect restorations or patina-ed racers, this one could be great to take in either direction…
