A Few, Very Rare, Race Bikes For Sale; Ex Roberts & Aoki

These three authentic race bikes are very special in their historical value, for winning and for not!

First Up:

Bike:  1999 Honda CBR900RR Erion Racing; Ex Kurtis Roberts

Location:  California

Price:  POR

The seller, RMD Motors, is sparse on the details, but it should be obvious what you’re looking at being that this bike is said to be authentic.  They do state that the bike produces 200hp at the rear wheel, comes with nothing other than what is in the photos (Read: No spares)–but that does include Kurtis’ actual leathers.

The AMA Formula Xtreme series is intended for production bikes, with some, but not many, rules on what parts of the bike you can exchange for aftermarket parts.  The intent of Formula Xtreme is to allow as many types of motorcycles to compete, anything from inline-fours to air-cooled V-twins.  Formula Xtreme racing is usually one of the more competitive and entertaining races of an AMA weekend; Many veterans such as Eric Bostrom, Jake Zemke, Josh Hayes, Nicky Hayden and Kurtis Roberts among others have cut their teeth in Formula Xtreme.

Erion Racing has continued to be a prominent name in Honda AMA racing with even a special Erion Racing edition CBR929RR released for the U.S. market by the manufacturer.  For 1999, Erion Racing was the winner of the Formula Xtreme championship with another title in 2000.  I’m not adept on the Formula Xtreme rules for 1999, but it’s obvious looking at the bike what some of it’s features are:  Race bodywork with mounts, analog tach’,  race fuel tank, larger radiator, Erion SS/Carbon full exhaust system, aftermarket triple clamps, Ohlins forks & rear shock, Brembo calipers, Marchesini wheels and I’m sure much more that I didn’t notice!  This is a chance to own a fantastic looking, legitimate, race bike with a championship under it’s belt.  I’m unaware how many races this particular bike won, I’m not sure about the 900 designation as this should be a 919 or 929 based on the year, but you still have a serious piece of AMA history regardless and I’m sure RMD would be happy to answer your questions.

See this Erion CBR900RR on RMD’s website here.

Next Up:

Bike:  2002 Kenny Roberts Proton KR3; Ex Nobuatsu Aoki

Location:  California

Price:  POR

As you may know, 2002 was the last year for two-strokes in MotoGP.  Two-strokes had their last hurrah in 2001, but couldn’t overcome the 490cc deficit they had to the four-strokes in 2002 and were finally obsolete–How you may feel about this is up for debate.  Regardless, Proton KR racing had a respectable finish in the 2001 championship with Nobuatsu Aoki & Jeremy Mcwilliams finishing 12th & 14th in the championship, respectively.  The disadvantages for the privateer team of Proton KR were immense and they didn’t receive much help from their V-3 format.  The four cylinder bikes of 500gp had the most tractable power delivery–If it’s possible to say that for a GP two-stroke–while also having the most power.  As an example, the NSR500v was a V-Twin example of Honda’s factory NSR500 designed for privateers and had nowhere near the power of the factory bike.  The theory was that the two and three cylinder machines had a lower weight and could out corner the larger bikes, in practice the two and three cylinder bikes hadn’t a chance but on a wet course or a very tight one.  The Proton KR3 debuted in 1997 and was a joint venture between legendary racer Kenny Roberts and Malaysian giant Proton.  While they may not have won any championships, or come close–and as frustrating as I imagine it was for KR–I’m sure “King” Roberts enjoyed it, I know I would have!

This example looks to be in fantastic condition.  The seller states that this bike will run and comes with a small selection of spares.  As I’m sure you can imagine, it would be no small feat to run this bike anywhere, especially when consumables are accounted for.  However, if you have the funds, ask yourself:  How many times does a 2001 500GP bike come up for sale?

See this bike on RMD’s website here.


Bike:  2004 Kenny Roberts Proton KRV5 XM2; Ex Kurtis Roberts

Location:  California

Price:  POR (Rumor has it $300,000)

The Proton KR KRV5 debuted in 2002 with the adoption of four-strokes.  The V5 in KRv5 denotes that this bike has a 60deg V5 arrangement and a displacement of 990cc, putting out 200hp @ 15,000rpm.  The bodywork appears to be the latter iteration of the KRV5, which is consistent with the Valencia technical inspection sticker.  For 2004, Kurtis Roberts was only able to finish twice in France and Brazil with 15th and 19th, respectively.  The bike for sale here shows a technical inspection sticker for Valencia in 2004, however Roberts never started the GP at Valencia in 2004.

So, what are you getting for your money?  As things stand right now, you’ll get a fully functioning seven year old, privateer, MotoGP bike with a minimal spares package.  This bike currently doesn’t hold the value that any of the factory bikes would and shouldn’t for a long, long time.  However, none of those factory bikes are currently available–that I’m aware of–and you’ll probably be waiting a very long time for one to pop up if you don’t already know someone who has one.

See the bike on RMD’s website here.

So, all of these bikes look to be from the same seller/collection, but which one is the one to have if you can only choose one?  Obviously, the most expensive will always be one of the Proton KR bikes, with a large gap back to the CBR.  My money says that the 2002 Proton KR3 will always be the most valuable bike of the three; The most important influence being that it is one of the last two-stroke 500GP/MotoGP bikes to ever be produced–privateer or otherwise.  The 2004 KRV5 will always be a interim MotoGP bike and if the rules are again revised to allow 1000cc bikes, it won’t even have a displacement draw.  The CBR is a National Championship bike, even if it’s only in Formula Xtreme, and that kind of provenance doesn’t come everyday.

There are two kinds of collectors these bikes are for:  One who has a decent amount of money to spend on a collector bike, and someone who has obscene amounts of money for a collector bike.  The Proton’s are obviously the expensive bikes with the Erion CBR checking the affordable box.  Both of the MotoGP bikes have parts that you’re never going to be able to purchase from any retailer, and I’m sure the CBR has some good HRC bits on it too.  I wouldn’t be ashamed to have any of these three bikes, but I’d absolutely love to have a final year Grand Prix two-stroke.  If nothing else, spend a little time to enjoy the photos!

Yellow and Black Attack: 1985 Yamaha RZ 350

For Sale: 1985 Yamaha RZ 350

RZ350s tend to be pretty popular here on RSBFS. Built in a limited 2-year model run, offered in only two color choices, and known as the last road-going two-stroke sportbike available in the US, the little RZ is an affordable classic that is a blast to ride.

Today’s RZ350 sports some significant modifications; if you are a collector looking for that 100 point authentic bike, please look elsewhere. For the rest of you looking for a ring-dinger to flog on the streets of your locale, read on!

If you looked at the first picture and couldn’t quite place what was wrong, this picture should help. The seller has replaced the stock RZ350 front end (with relatively wimpy tubes, narrow tires and 267 mm disks) with a complete unit out of an RG to provide a more stout platform on the front. The upside here is that modern, sticky sportbike rubber can now be used.

Out back, a similar transformation has occurred, once again allowing for wider rubber to be fitted to the bike and enhancing its cornering capabilities.

From the seller:





So what will it cost you to get onto a buzz-bomb and smoke out all of your neighbors? Fortunately, RZ350s are collectables at the lower end of the price scale. There has not been a lot of upward price mobility on these models, and clean examples will bring $3-5k. The mods on this bike detract from collector value, but since that value is not very high to start with, the mods probably will break even from an investment perspective. Undoubtedly, the mods help add to the hooligan factor, which is what this bike is all about. Here is a good shot of a stock RZ350. You might even recognize the guy sitting on the bike.

Bidding is going on now, with the auction at the $2k mark. The reserve has not yet been met, but I can’t see it being much above $2,500. To get into the action and get yourself a bumble bee that can sting,

I’ll have a blue (smoke) Christmas: 1984 Yamaha RZ350

For sale: 1984 Yamaha RZ350

There is nothing like a nice RZ 350 to get you into the Christmas spirit. Admittedly this is not the nicest RZ we have seen in the pages of RSBFS, but it is the last legal, road-going two-stroke brought into this country by a major manufacturer – and that deserves a little oversight on our part. Besides, for those of us who find million dollar MHE twins a bit pricey, this bike fits nicely into more modest budgets.

From the seller:

The seller is not making any attempt to hide the damage, and from 30 feet away everything looks pretty minor. It even has Toomey pipes on it! After a glass or three of eggnog, I can almost hear the ring-a-ding-ding of Christmas. All you really need to do is ask Santa for a new windscreen and you will be able to deck the halls – as well as a few unsuspecting middleweights.

As described in previous RSBFS posts, RZ350s are fun little strokers that are getting harder to find. This one is not in ideal shape, but the major bits are all there. If you want to get in on the affordable classic collectable, this might be your chance! Click on over to the auction and

1985 Yamaha RZ350 in California

For sale: 1985 Yamaha RZ350 2-stroke

Located in La Puente, California, this clean 1985 RZ350 provides you another opportunity to grab that elusive 2-stroke that you might have missed in the showroom back in the 80’s. Although these bikes are not as rare as some of the hand-built Italian hardware we occasionally see on RSBFS, finding a good example of a survivor is difficult. Let’s look at the bike:

From the seller:
Up for auction is a used Yamaha RZ350. The motorcycle is in very good condition overall and has low miles for its age. It is all stock except for the exhaust, they’re Allspeed and they appear to have been ceramic coated. This motorcycle has a clear title and includes all service records from original owner. The bike has sat for approximately 3 years and has not been started, so I would assume the carbs are going to need to be cleaned and the fluids changed, plus it needs a new battery. I have a new battery I will throw in but I don’t have the acid for it. This RZ350 ran great before it sat, it does have a very slow oil leak on the left lower side of the engine(had the leak when it was purchased). If you would like more pics please ask.

The mileage is listed at 7,647, which is not a lot for a bike this age. The bike is not completely original – it has aftermarket expansion chambers – but the modifications are period correct and definitely enhance performance. The exhaust is ceramic coated to boot!

The opening bid is quite reasonable for one a RZ350, and there is no reserve on this auction. This is your chance to grab one of these great bikes –

1985 Yamaha RZ350

1985 Yamaha RZ350

2-stroke mania continues here at RSBFS. Here is a rare RZ350 in red/white for your enjoyment. This example has seen some use, but looks to be in good condition for its age.

There is very little information regarding this gem in the ad, although the seller lists it as a California bike with 8,959 miles. The auction has the bike mistakenly labeled as an RC350 rather than an RZ350, so that might keep some people from finding it. But not us!

Offered in the US for only a short period of time, this is the second (and last) year of the RZ350. Earlier (1984) paint schemes had the yellow/black with Kenny Roberts’ signature, and the red/white without a signature. In 1985, Yamaha added Kenny’s sig to the red/white paint scheme as well.

This bike sports a set of Spec II expansion chambers. As the OEM exhaust system contained a complex (and heavy) set of catalytic converters to help the bike pass EPA emissions, aftermarket systems helped to shed 15+ lbs and offered substantial performance improvements.

Although not quite as fast as the 550 four strokes of the day, the little RZ built up a strong cult following and continues to be an affordable collectable that is fun to ride. Check out this one here!

1985 RZ500 Hybrid Track/Street Bike In Florida

1985 RZ500 Hybrid  Track/Street Bike In Florida

Here is a rather interesting RZ500 hybrid looking for a new home.  It’s got a little of everything on it but it has one very important thing for us two stroke fanatics: a title.  That is a tasty custom swing arm sitting there and with a nice paint scheme that YZR replica bodywork would look great.  A lot has been done do this bike so I’ll let the seller explain:

Time to settle and cash out. 1985 RZ500. ZXR750 forks,Marchasini front 3.5 rim with brembo brakes and cast iron rotors,GSXR 5.5 rear rim withm modified cush drive in a Custom swing arm. Steel re-enforced frame @ main frame. Engine has fresh top end with 32mm flat slides,Bodywork is YZR500 fairing with air tech seat assembly. Fresh slicks on her, a full un opened 55 drum of MS109 VP fuel, and here is the rather cool part…With a few zues fastners and one bracket I made for the tail assembly its street legal,….OK so its a rather odd machine but its titled and has seen some street miles. Instrumentation consists of a tach and temp gauge.
I do not care if it sells but if you wish to have it it is available. I last ran it a bit over a year ago at Jennings and while it won both classes its was not what I expected and lost interest in my vintage conquest. Right now it is collecting dust in a conditioned space waiting to be gone over or loved on.
Paint is in decent condition and spares consist of sprockets and a spare set of YZR bodywork depending on interest.



The seller is asking $7500 and he sounds pretty firm on that.  In the two stroke market I consider a title worth somewhere between $1500 and $2000.  So factor that into your equation when you consider if the price is right.  Obviously the bike is currently set up for the track.  It would take a little work getting her ready for the street but the owner has done the hard part already with the title.  This bike is probably not for the collectors out there but is for the guy who wants to wring a two strokes neck every weekend.   Tear up that Sierra Club membership and come join us on the dark, or shall I say smokey, side.  The owner sums it all up perfectly with a saying under his avatar on the WERA forum:  “Valves are for toilets!”   The bike is listed for sale on the WERA two stroke forum.

1978 Yamaha TZ250E

Located in Menlo Park, California is a completely original 1978 Yamaha TZ250 with less than five miles.  To quote the seller:

1978 Yamaha TZ 250, less than 5 break in miles if that .
This example has never even broken in. Garaged since new, will need new rubber & seals. Campagnolo 5-spoke alloys, fairing & duck-tail seat. Minor dings & scratches from sitting for so long, you will not find another one in nicer or newer condition.

Some information about 1978 TZ250s from Motor Bike Search Engine:

Introduced in 1978, the ‘E’ version of Yamaha’s all-conquering TZ250 production racer featured a new chassis frame. Retaining the same ‘monoshock’ rear suspension layout (complete with adjustable pre-load and compression damping) as its forebears, it relocated the famous twin-cylinder, two-stroke water-cooled engine some 20mm further forward. Mounted on special alloy plates, this remarkable unit boasted Hitachi’s automatically advancing / retarding CDI ignition system and Mikuni VM34SC carburetors. Reputed to develop 53bhp @ 10,500rpm, it was mated to a six-speed gearbox and reined in by front / rear disc brakes. A stepping stone in the careers of such riding greats as Kenny Roberts and Tom Herron etc, the TZ250’s influence reverberates to this day.

The asking price is firmly set at $7,500.  It would be nice to see this time machine cleaned up and on display–it would take some serious work to get it back to racing condition.  See this fantastic barn-find on Craigslist here.

2006 Yamaha R1 Limited Edition–Still in the crate

Again, I know R1s aren’t rare but, the LEs are and this one is still in the crate.  Located in Cedar Hills, Oregon is a 2006 Yamaha R1 Limited Edition in unused condition.  To quote the seller:

I have a 2006 Yamaha YZF-R1 Limited Edition for sale. This is one of only 500 ever produced, and still in the original crate at my warehouse. It’s in pristine condition, has never turned a wheel except maybe after it rolled off the assembly line and into it’s shipping container.  This bike sold for $18,000 new, and I purchased it primarily as a collector’s item never intending to use it. A nice display piece for sure, but would be great for weekend rides, or track days for someone who wants one of the best all time sportbikes, unmatched for it’s speed, powerful engine and superb handling.  The bike is still in the crate, but I will be happy to assemble and service it for the new owner. I am a career Honda, Yamaha, Kawasaki, and Suzuki tech.  A factory service manual, owner’s manual, and Limited Edition R1 tool kit will be included with purchase.

The asking price is $12,995.  So, if you missed the Limited Editions around the first time or you’re a very serious collector, this might be the bike for you.  Sorry, no photos.  See the Craigslist ad here.
