Four-Valve Genesis: Pristine 1991 Ducati 851 for Sale

1991 Ducati 851 Front

Long forgotten in the wake of the 916, the Ducati 851 and 888 have seen a resurgence in popularity in recent years, likely because they are seen as the genesis of Ducati’s four-valve, liquid-cooled v-twin superbikes that may have reached its apex with the Panigale: Ducati is struggling in WSBK and there is talk of a move to a V4 format in the future, which would likely mean a V4 roadgoing superbike as well…

1991 Ducati 851 Tail

Ducati L-twins have always been fundamentally tough machines. Designed to handle the rigors of the track, the roadbikes were always relatively understressed, and while the air/oil-cooled two-valve engines can be tuned to make significantly more power for the track, they’re still unable to compete against liquid-cooled, four-valve four cylinder engines.

1991 Ducati 851 Fairing

In order to stay relevant in racing and, by extension, in showrooms, Ducati needed a new bike to compete in the fledgling World Superbike Championship. The 1987 Ducati 851 was the result and while the skin was all-new and modern, it was what lay beneath that was most important. Based on the existing air/oil cooled engine, but now with four-valve heads and a radiator strapped to the front, the newly-dubbed “Desmoquattro” put out 93hp at the rear wheel along with the healthy midrange you’d expect from an Italian twin.

The bike was successful and quite literally put Ducati on the modern performance map, going toe-to-toe with the best Japan had to offer on track and on the road. It was followed by the similarly-styled 888 that featured, surprise-surprise, an 888cc engine, before being replaced by the significantly redesigned and restyled 916.

This 851 is one of the nicest and definitely one of the best-photographed bikes we’ve featured recently. It’s a stunning, low-mileage, one-owner bike that’s largely stock, other than the slick, vintage Fast By Ferracci cans, making it perfect for collectors.

Corbin Seat!
Bike is new… Nothing more to say!

With just two days left on the auction, bidding has been active so far, although well below the $11,999 Buy It Now price. That’s certainly big money for an 851, buy you’d be hard-pressed to find a nicer, lower-mileage example: at just 3,500 miles, this thing hasn’t even seen its first valve-check yet. And you’d easily spend that much to get a shoddy example into this kind of shape. If you’re looking for a nearly perfect 851 to complete your four-valve collection, this is your bike.

Buzzy Little Bee: 1985 Yamaha RZ350 for Sale

1985 Yamaha RZ350 R Front

Yamaha made a name for itself in the US building giant-killing two-stroke parallel twins that powered the RD and later RZ models like this 1985 RZ350. The 347cc engine reatured liquid-cooling and made over 40hp stock, with plenty more available with careful tuning. While Honda largely focused on their heavy, but very sophisticated two and four-cylinder CB motorcycles, Yamaha’s whippy little two-strokes terrorized backroads and race tracks all over American and Europe, creating a cult following that persists to this day.

Two-strokes have never lacked top-end power, but their light-switch power delivery left something to be desired for street riders and, in th 1980’s Acronym Wars, the “power valve” was born. Yamaha’s version was, of course, known as the YPVS that used a computer to adjust the exhaust ports. The “Yamaha Power Valve System” plumped up the midrange of the raspy little two-stroke, meaning you could have your cake and eat it, too. Assuming you didn’t mind a little blue smoke in your eyes…

From the original eBay listing: 1985 Yamaha RZ350 for Sale

The 1985 Kenny Roberts Edition RZ350LC offered here is one of the quite rare leftover models with revised graphics that somewhat resembled the 1983 UK versions, but with gold rims and the Kenny Roberts signature, originally sold as an RZ350NC2 in California only from late 1985-6. It has been owned from new by only two enthusiasts and has been very tastefully modified with an original 1985 full fairing and Corbin Gunfighter single seat. Mechanically, the hugely desirable Pro-Design Cool Head was installed for increased cooling, and a Toomey exhaust.

The bike runs exceptionally well. It starts easily, idles well and has great power delivery. It shifts through all gears perfectly with a good clutch. Suspension feels taut and the brakes work very well, front and rear. Cosmetically the bike is in good condition with the usual scuffs of a bike with 17,000 miles, that is 32 years old.

The bike comes with a clean, clear California title and a substantial box of spare parts, including stock fairing, original exhaust pipes, turn signals, etc.

These are not bikes for the inexperienced or faint-hearted, with huge wheelie-popping performance on tap when the revs rise.

1985 Yamaha RZ350 Pipe

This particular RZ350 features a very stylish full-fairing that I’ve seen on several bikes for sale recently. I’m not sure if it was a factory option or not but, painted to match, makes for a very nice machine with light weight and bike-bike style. Parts availability to keep an RZ running should be no problem, but the included spare parts is just icing on the cake.

A price of $6,900 means you’re looking at the higher-end in terms of pricing for these, but it looks like you’re getting a well cared-for, thoughtfully-improved, and very practical classic for your money.

Dear Santa: One Owner 1985 Yamaha RZ 500

The RZ500 is one of the most popular bikes on RSBFS, and we love to bring you clean examples of the breed. This particular bike is being sold as a one owner Canadian import with 31,000 km on the clocks.

Update 2.23.2013: Previously listed in December of last year, this RZ500 was bid up to $9,599.99 with no sale (22 bids – showing good interest). Thanks for the heads up Jim. Links updated. -dc

This looks to be an honest specimen; not perfect by any means, but ridden and relatively well cared for. Modifications – if any – are not obvious, although given the mileage a top-end rebuild might be in order soon. Buyers tip: If you are not familiar with two strokes, please do not ask the seller if it smokes upon start up!

From the seller:
1985 Yamaha RZ 500 Red with white color scheme. 31,000 kilometers(about 19,500 miles) V-4 two stroke engine with YPVS. one owner bike purchased new in 1985 from the Candian Yamaha dealer.Brought into the USA and registered and titled in the same state since new. Totally original in very good condition with original paint on the tank. The bike shows well and runs very well, once I purchased it, I had all fluids changed, the bike has a new airfilter and battery.

The body work has some small scratches under the grab rail on the back, the body work around the area where the turn signals come out has a small amount cut out of it probably from the bike falling over at some point as the front brake lever is bent. I see no evidence the bike has gone down at speed and the tank is undented and original paint as is the rest of the body work. The first owner who I purchased the bike from was about 50 years old when he purchased it new so it was always owned by an adult, he used it for commuting which how the miles were put on the bike. The YPVS powers right up when you turn the key on and the bike runs out very nicely.

This is a chance to purchase a very rare and exciting motorcycle. The bike comes with the original factory shop manual, the original factory parts microfische, various jets, a copied parts manual. I have a receipt for a new clutch that installed in the past.

The bike is located in Northwestern Connecticut about 75 miles north of New York City

As if to prove that RSBFS is a bellweather to all things cool and desirable, the bidders have turned out for this auction. The current price is up to $8,100 with reserve still in place, and bidding has been moderate. The bike has been listed elsewhere on the internet for $12,500, so it will be interesting to see at what point the reserve comes off.

Clean Survivor: 1984 Honda VF500 Interceptor with 2,410 miles!


If you are looking to add something period-specific to your collection without paying crazy money and breaking the bank, this just might be for you. Known in the day for raising the bar in the middleweight class (remember when a middleweight was only a 500?), the smaller Interceptor features a jewel of a V-4 motor housed in a Superbike-inspired chassis. A sportbike with a V configuation motor that is NOT Italian – who would have thought?


The mini-ceptor was thrust upon the scene where air-cooled Kawasaki GPz 550s ruled the streets. Yamaha uppped the displacement ante with the FJ600, but it was Honda who threw technology at the problem of performance and created this liquid cooled gem. This particular bike sports only 2,410 miles on the odometer, and from the few pictures looks to be in pretty good shape with plenty of records.


From the seller:
have a 1984 honda interceptor 500 showroom condition with 2410 miles clear iowa title stored indoors and in perfect shape $3500. i have all service records and dealer welcome letter. carbs have been completely gone through all new bowl caskets and carb boots. new front fork seals / oil and filter and valve adjust. never laid over pipes are perfect. these are becoming collectors items and you will not find many with this low of miles.

the $3500 is what it is listed for local , the reserve is MUCH lower then that . for what i have it set at i am giving this away !


The very early release VF500 Interceptors had a bad habit of destroying crankshafts, but this was very rapidly handled by Honda under warranty. You might want to check the ‘net to make sure the engine number puts this unit in the clear just to be safe. Beyond that, given the miles, the condition and the price, can you really go wrong? Check it out here, and let us know if this is the type of survivor you like to see here on the pages of RSBFS!

Another RZ500: 1985 Yamaha RZ500 in Oklahoma

Ah, Christmas is in the air. Two stroke smoke is everywhere, and rare motorcycles abound. I love this time of year – possibly because the RSBFS corporate offices are located where we can ride year ’round – but also because of the great bikes that seem to bubble up to the surface late in the year.

From the seller:
Restored !985 Yamaha RZ500. Approx. 900 miles ago, this bike was completely disassembled and the frame, triple trees, rear sets, rear calliper, and many other brackets & pieces powder coated black. New bearings, bushings and fasteners were used in reassembly. All pivots, bearings and bushed items are very tight without the normal “play” that would be evident with this mileage. Factory Yamaha bodywork was painted Red & White with only a couple of small chips on it today as to be expected on a bike of this age. The engine was rebuilt with Yamaha components and is on the first overbore .025. and the crosshatch is still very evident in the cylinders. New Battle Ax tires installed less than 100 miles ago.

From the seller:
The history on this bike I have been able to obtain is a Yamaha dealer bought it at an auction in Approx. 1999 with 35,368Km’s (21,976 Miles) He told me when he purchased it, it was in the same condition it is today and he prepared it for storage and displayed it in his dealership showroom. The Yamaha dealer sold it to the man I purchased it from in 2009 still showing 35,368 Km’s. and today it has 36,820Km’s (22,878 Miles) showing it has been ridden a mere 1,452Km’s (902 Miles) since Approx. 1999!

I purchased this RZ500 in November 2012 for a RZ500 project I have. I have since purchased two other stock units and no longer need this one. I have another 1985 RZ500 that I will be listing soon but is no where near as nice and as this one. This is a very strong running, well handeling RZ!

I took the fairings off the bike so the stock airbox, exhaust, ect. can be seen. If you want a specific picture please let me know and I will get it for you.

This is a pretty clean looking RZ. The seller claims most of it to be stock. The re-sprayed livery looks good in the pictures, although I am partical to the stockers “checkerboard” graphics. Given the mileage (22k and change), the seller has done some work to keep this bike floating above the maintenance curve. With a new top end and first overbore, this smoker will be making ring-a-ding and popcorn sounds for many miles to come!

This auction is on right now and the opening bid was a reasonable $5,000. Bidding has been very light thus far (has interest in the big RZ begun to wane?), and there is still a reserve in place. For your chance to check out the second RZ500 this week, click the link and jump over to the auction. Good Luck!

Turbo Tech: 1983 HONDA CX 650T Turbo

For Sale: 1983 HONDA CX 650T Turbo

And now for a completely different kind of v-twin experience. Loosely based on the CX500 / CX650 powerplant found in Honda’s cruiser/custom lineup as well as the midsized Silverwing touring bike line, the CX650T added a Turbo and cutting edge technology to produce a bike that was outstanding on the road, and miserable in the showroom. When it comes to rare, the unwanted and unloved Turbo bikes of the early 1980s are about as rare as they get for non-homologation, mass production bikes.

The Honda Turbo lineup, which started with the CX500T a year earlier, produced a unique motorcycle. It wasn’t a sportbike, and it certainly was not a dresser. Yet with shaft drive and enough torque to earn the title of “roll-on king,” the Honda Turbos could easily fulfill the role of sport-tourer. All it was lacking was hard bags. With a relatively tall stance and a hefty 500+ pound mass, the ride is comfortable and relaxed. The fairing works well to keep the rider protected, and the power is worth waiting for (turbo lag, while greatly reduced with the switch to the 650 motor, still exists).

From the seller:
Here we have a 1983 Honda 650 Turbo. This model was the lowest production number Honda manufactured with a total of 1776 units sold worldwide. This pristine example is showing 6890 miles.The bike is in collector quality condition and would make a fantastic addition to any serious collection. It is all original down to the Bridgestone tires and those may even have the original air in them. The tires are showing some slight weather cracking on the sidewalls. It starts, runs, drives and stops 100%. All electrics work including the clock and all lights and gauges. It has always been properly stored in a climate controlled garage. The bike is titled, insured and tagged in my name. Thanks for looking and good luck. Someone is going to get a very nice bike.

The CX motors have turned out to be relatively bulletproof. For all the power these bikes produce on boost, maintenance needs are not excessive, and the bikes are not overly fragile. All these models do have a penchant for eating stators as miles accrue (15 to 20k is the general rule), and there have been reports that some of the wiring connections are weak (possibly a related issue). Other than that, keep it full of oil and gas and keep the boost gauge active and you should be good.

This fantastic looking survivor is available via auction. Bidding has been moderate, and the current price is just below $5,000 with reserve still in place. Expect to pay approximately $6,500 or more for a good 650 Turbo; anything below that for a low mileage example should be considered a bargain. I’m not sure if original tires with original air has any collector value, but the rest of this bike sure does. For more info and pictures, click the link and jump over to the auction. Good Luck!

Rolling Stock: 1985 Yamaha RZ500

For Sale: 1985 Yamaha RZ500

Update 6.20.2012: Back on eBay and it looks like for the last time as it’s now no reserve. Thanks for the heads up Jared! Links updated. -dc

Update 3.8.2012: Mileage is now stated as 9300 miles and buy-it-now dropped to $15k. -dc

Hot on the heels of Ian’s post on a modified RZ500 comes this beautiful survivor. How many stone stock RZ500s do you find in the States? Those who have looked will tell you – not many. Perhaps it is because so few RZ500s made it to the US in the first place (Yamaha never officially imported it, so all are grey market bikes), or maybe, as Ian stated previously, RZs tend to be on the receiving end of heavy modifications. Any way you slice it, a stocker from ’85 is definitely a rare find.

This particular bike looks good in the pictures, has the stock chambers, retains the dinky 16″ front wheel (inspired by GP technology of the day) bolted up to 37mm forks (equally dinky by today’s standards), and offers the solo seat cover (a passenger pillion is hidden beneath). All the reflectors are in place, and the turn signals have not been cut down or otherwise modified. From afar, this looks to be a showroom RZ500.

From the seller:
This is a 1985 all original Yamaha RZ500. has a Canadian title and is in South Florida. Not a big problem to title in States as it is considered an antique. Is in great shape with low miles. A real classic eye catcher.

So the BIG question is what is a 1985 RZ500 sporting 30,035 miles on the clock worth? Values on these bikes have been all over the place, but mostly on the up. We have seen lower mileage examples offered at $20k, but no real evidence of them selling at that level. This particular bike is being offered with a starting bid of $9,500, and a BIN set at $18,000.

This bike just hit the market, and interest has been relatively low at the time of this writing (zero bids). The opening ask is not out of line with the bike’s value, but perhaps bidders have been scared off by the BIN? For more info and details, click the link and jump over to the auction. This is a good looking example of a rare breed. Good luck!

Unmolested Original: 1984 Yamaha RZ350

For Sale: 1984 Yamaha RZ350

Condition: All original

Mileage: 4,300 miles

Price: $7,000

The Yamaha RZ350 is one of the most popular bikes on our site, and it is simple to see why: The last of the legal two strokes, the RZ350 makes all the right noises while really looking the part; the livery evokes memories of King Kenny Roberts, right down to his signature on the fairing. With the YPVS valve in the exhaust port, the RZ350 was the most tractable two stroke of the day, and performance was on par with the current crop of 550cc fours.

The RZ was a two year only bike in the U.S., and Yamaha did not move many units. Fast forward nearly 30 years and the RZ has become more desirable and more rare – especially in this kind of condition. It is not often that we find a completely stock RZ350, right down to the original exhaust (with the innovative catalytic converters). This bike is so stock that it still has all of the original reflectors hanging off of it!

With very low miles (4,300), this bike has travelled approximately 150 miles for each year it has been on the road. This is what really makes this an interesting collectable: it has few enough miles to be nearly new, yet enough miles to encourage the occasional ride. With the value of these machines on a continual rise, this is an investment that you can enjoy for years to come.

From the seller:
On a 1-10 scale this bike is an 8.5. I am the second owner and have had it since it had 500 miles on it. The bike has never been wrecked or dropped to my knowledge and the engine and transmission have never been into, it runs and rides great. The bike is mostly all original and even still has the catalytic converters on it. The bike has been maintained by me and the local Yamaha dealer. There has been some minor touch up done to the paint. 1 smaller than a dime spot on the right side of the tank (very small spot and then tank was recleared). A couple of small touch ups on the bars, brake fluid reservoir and on right side engine cover. I am a very meticulous person and have kept this bike in near perfect condition. I am asking $7000.00 for this bike. I have more pictures on request.

With an emerging collectable such as this, prices are still relatively sane. The seller has shared good detail about the machine, and is willing to share more with interested parties. Here is a chance to own an all original RZ for a fair market price. Given that nearly all the RZs we see have had some modifications, this particular bike is a pretty incredible find.
