Featured Listing – 1986 Yamaha RZV500R with just 4,100 miles !

Many of Yamaha’s RZV-500R’s ( or RD500LC ) have been used, some might say, as intended – and look somewhat worn for it.  But this originally British collector example has traveled only 6,586 kilometers and is in tip-top shape.

1986 Yamaha RZV500R ( Portugal ) for sale on eBay

With many years of championship racing aboard the YZR500, the mid-80’s were now or never for a 500cc two-stroke race replica.  The double crank engine had similarities to the racer, but had a smoothing balance shaft and YPVS power valve set-up.  Power was nearly 200 hp per liter with 88 hp at 9,500 rpm.  The carburettors are side mounted and look past the square-tube steel frame toward the engine.  Conventional forks are air adjustable and carry 267 mm front disks.  The smaller 16-inch front wheel sharpens up turn in on the 436 lbs. ride.

Presented by a Portuguese collector, this RZV500R appears un-restored and basically as new.  Beside the bespoke GP exhaust, changes to the square four 500 would be unconscionable.  Right down to the tall tires, it’s as issued 35 years ago.  Comments from the eBay auction:

Yamaha RZV500R fully restored. Mint condition.

Matching Numbers. No needs any work. All working perfectly! 

Year 1989 with 6,586 km

Jim Lomas Full exhausts but original ones are included on this sale.

Used to be a UK bike but now has Portuguese documents.

Please feel free to ask me more pictures or videos.
Francisco represents the collector and asks £17,000 for this classic superbike, about $21,875 today.

The RZV-500R reviewed as the “real” Kenny Roberts replica, with its small cockpit and off-or-on power train.  Francisco’s edition has the mileage of a one year-old machine, and the accompanying cosmetics.  Offers welcome on 011 351 9 1652 4741 or via email – here -.

Chi Slamma Gamma – 1986 Suzuki RG500

Fully ten years after Barry Sheene won the GP world championship on his RG500, Suzuki had tamed the beast for the showroom.  Though the delay missed the window of opportunity in the U.S., many examples have been imported, and this looks like one of the finest.

1986 Suzuki RG500 Gamma for sale on eBay

Unthinkably complex in this day of 400cc singles, the RG was actually two 250cc twins geared to a common lay shaft, which was protected by a shock damper on the road machine.  The low-profile 28mm Mikuni carburettors and their air shared filter are wedged against the sides of the fairing, with disc induction valves underneath.  Suzuki’s Automatic Exhaust Control power valve system and expansion chambers made their way aft closer to the centerline.  Alloy chassis and cast frame connectors  are seemingly more modern than the earlier race bike, the seat fairing covering the upper exhausts and stretching all the way to the footpegs.

With just over 6,000 miles, this Chicago resident is even better looking than the odometer would suggest, with no evident runs, hits, or errors.  The owner says this in the eBay auction:

As you can see from the photos in the photo section as well as the body of the description, the machine has had absolutely no restoration performed to any part of it.  The condition is exactly what it looks like in the photos.  I looked at a quite a few of these bikes before I finally bought this one, and I’ve never seen a better original one before or since.

The paint on all of the fairings, tail section and tank is original, and have never had any type of paintwork or touchup.  The fairings have never had any type of cracks or damage.  The bike has never been in any type of accident or been dropped at any time.

The RG500 runs and rides the way you expect a machine with this type of mileage to run.  All of the mechanical components have been checked over to ensure they work properly including the clutch and brakes.  The fuel delivery system was also completely gone through this season and functions perfectly. 

Suzuki began the square four saga with two 125’s making 250cc, and offered a 400cc variant alongside the 500 in appropriate markets.  But the RG500 was the race winner, and the great powertrain was in a 340 lbs. ( dry ) package, a power-to-weight ratio that was years ahead of its time.  Bidding is quite active but hasn’t met the reserve, and we’ll be keeping an eye on this one.

Update 3.15.2018: SOLD IN ONE HOUR! Congratulations to buyer and seller. -dc

Please note: Ted from AutoManiaGP has asked us to open the comments on this post in the hopes that the RSBFS community can assist in determining what has been done to construct this bike. There was no accompanying documentation and we would appreciate your help by examining the pictures and commenting with any additional information you can provide. The text below is our first shot but we look forward to what else can be learned. Please forward widely and thank you for your help! -dc


Suppose you had been a racer, and owned a race team, over the years acquiring intimate knowledge of several different brands of factory race gear – what might you build as a street machine?  The few production years of Suzuki RG500 Gamma imprinted Mike Canepa of 10K Racing, and he put together a race-derived machine with Spondon Engineering chassis, with trackside details stem to stern, in race livery.

Suzuki RG500 For Sale at AutomaniaGP

Suzuki’s RG500 used a twin-crank square-four two stroke, with almost unmatched power-to-weight, 95 hp in factory street tune.  No doubt well above that with racing carburetors and exhaust.  Like any privateer’s racebike, specs are hard to come by, but this RG appears to have a Spondon chassis, an English specialty manufacturer with a long history of chassis development for major manufacturers and well-heeled weekend warriors.  The twin spars are at least twice the size of a road-going RG.  Later upside-down Showa forks are installed, with Nissin 6-pot front calipers radially mounted.  The swingarm is thought to be from a Yamaha TZ250, an asymmetrical fabrication with a massive right side but straight left side with a brace to allow the chain to pass through.  Fairings are quite like a later RGV-500, with air scoops just above the front fender feeding the four sidedraft carbs inside.

Unlike any actual racer, this RG500 is clean, polished, and road legal despite the Skoal Bandit graphics.  Trim carbon mudguards are installed, along with a full featured instrument cluster.  Conflicted as the four expansion chambers and turn signals, there’s a locking gas cap on the tank.  The fairing’s post-and-pin supports are safety-wired to keep the cotter pin around.  Consigning dealer Automania of Oregon has a great collection of pictures – here – and says this about the bike:

Mike Canepa, owner of race team 10-K Racing was in the later stages of building this race bike for the street when he passed. I had been hearing about it for over two years and unfortunately did not pay attention to what he was telling me at the time. Hind sight is 100%. The engine is V-4 Two Stroke out of a 1986 Suzuki RG500 according to the records we found, but everything else has been a guess or information others have offered up. It was not finished, but he had been riding it recently.

This motorcycle is based on a 1986 Suzuki RG500 but everything except the engine is either custom or race track sourced. The rear swing arm looks to be from a 1991 Yamaha TZ250, the front forks Honda RS250 and the frame appears to be a Spondon that had no identifying numbers or manufactures id on it. It has been titled with an assigned OR State VIN plate and the bike is registered for the street. I am open to anyone looking at the images and suggesting where they think the parts came from. Don’t be shy…

The selling price is $16,695. The VIN# is ORSPERG9G1003 and miles are unknown.

Hard to tally up the hours and dollars invested in this racer-with-lights, though the preparation is immaculate.  Likely the frame has a pedigree, and Spondon Engineering has quite a following, even a fan website for reference.  Power-to-weight is probably more important here than on a factory machine, and the weight should be closer to 300 than 400 lbs.  Evidently inspected by Oregon DMV, it is titled and has road registration, which speaks to how close to completion the bike is.  RG and RGV did well in the 500cc years of Grand Prix racing, accounting for four championships and seven constructor’s titles.  Automania invites knowledgeable comment and asks $16,995 for this one-of-one, and can be reached at (541) 479-8888 or emailed – here –.
