Really clean Yamaha RZ350 in Los Angeles

For Sale: 1984 Yamaha RZ350 Kenny Roberts Replica

With bikes like this up for grabs, Los Angeles is truly the City of Angels. This great looking RZ was spotted by a sharp RSBFS reader – and we jumped at the chance to post it. We come across many hot rodded bikes in our quest to post the best of the best, but few offer the complete package that this RZ represents.

From the seller:
1984 Yamaha RZ350 Kenny Roberts Replica Excellent condition, This bike gives you a huge premagrin as you go down the street.
I’m finally selling my very loved RZ350. This is one of the cleaner RZ’s out there period.
The top end was rebuilt 1,500 miles ago. The crank was rebuilt by the guy I bought it from.
This bike is fast, very fast. 65 RWHP. Stage 3 Porting and rebuild done by Steve Turner (MBSteve), He’s a So Cal 2-Stroke tuning legend.

Here’s a list of mods done to the bike,
Stage 3 Porting, 34mm Mikuni Flatside carburetors, Billet aluminum intake manifolds,
Spec-2 expansion chambers, with M-Factory West Carbon Fiber Silencers by TZ-MIke,
New CDI rebuilt by RZ’s Unlimited, Tarozzi Rear sets,
Penske Rear Racing shock-ajustable, Progressive front springs, Telefix fork brace
Spec-2 Telefix, Full Faring, Spec-2 Telefix Rear Tail section with custom seat,
Custom made cluster mount (doesn’t move when you turn the handle bars)
Custom triple clamp, CRG Mirror (not on the bike) Steering Stabilizer, Custom Steel braided brake lines front & rear………just to name a few

Many spares are included. I have all the OEM bodywork (except the upper faring) which is in excellent condition, Lower bikini, Tail section, Seat, Left & Right side panels.
1985 RZ350 cdi, quick throttle, stock carbs & much more
The bike is plated and registered.

Please email me at

From the pics on Craigslist, the bike appears to have approximately 20,000 miles on it. The seller is asking for $5,500 which is a bit high for an RZ, but potentially justifiable given the condition and modifications. I think this is one great looking bike. To check out the complete add and all the pictures, jump over to Craigslist here.

Smoke ’em if you got ’em: 1984 Yamaha RZ350

For Sale: 1984 Yamaha RZ350 Kenny Roberts Edition

For those of you looking for fun on the cheap, here is a nice ’84 RZ350 in classic Kenny Roberts colors. These little bikes are lightweight, offer nimble handling, have decent power, and make all the right noises. Unleash your inner hooligan and cover your tracks with a fog bank of blue smoke!

The RZ350 offered the Yamaha Power Valve System (YPVS), which automatically controlled the height of the exhaust port – greatly improving the powerband of this two stroke.

From the seller:
1984 Yellow Kenny Roberts RZ350
Genuine Yamaha fairing 31K all rubber mounted
Toomey Pipes
Toomey air cleaner
Solo seat tail piece
New fuel and oil hoses
Fresh coolant
Less than a thousand miles on new Bridgestone Battlax
Matching engine and frame numbers
Runs great, very fun bike
No dents and just a few minor blemishes
Yellow plated bolts
Clip on handle bars

This has been a great little bike, and I hate to even sell her after all the detailing I have done. It’s time for me to move on my new Sportster. Lower chin cowl has a few small cracks but I think all of them do that have original plastic. That’s is why I have rubber mounted all fairing fasteners. As you can see from the photos this is one clean bike.

This particular bike has quite a few miles (42,000) and a few mods, including the Toomey pipes, a welded crank, clip-ons replacing the original bars, and more. The price for modded RZ’s has not really risen in the past year, and this could prove to be a barrel full of fun at a bargain to some lucky bidder.

The auction is currently at the $2,000 mark with reserve not yet met. I can’t imagine the reserve set much higher than $2,500 on this bike, and it should sell in the $3k-$5k range. For more information or to pick yourself up a fun little gem, click the link and . Good Luck, and may you never kick that smoking habit!

What is the EPA? 1984 Yamaha RZ350

For Sale: 1984 Yamaha rz350 RZ 350

The RSBFS staff seem to love these little bikes, judging by the number we have found and posted over the years. Some have been well kept and loved, others hot-rodded and modified within an inch of their lives, including porting, pipes, new suspension, and more. Today’s bike is surprisingly stock; it is claimed all original, and still has the original exhaust (which contain catalytic converters to try to clean up the RZ’s notoriously dirty two-stroke output) and original front tire (!).

From the seller:
1984 Yamaha RZ 350 Kenny Roberts. Own a piece of motorcycle history. This is the first year the rz was offered in the U.S. The last of the street legal two stroke’s in america. This bike is in very good original condition. A very low mileage bike. Only 4061 original miles. It doesn’t get much better than this. I have a clear title and original owners manual. Bike runs great and still has the original front tire still on it!

With just over 4,000 miles on the clock, this little RZ is a real survivor. Performance is adequate in stock form, although keep in mind that we are only talking about 350cc here. Tires would be at the top of my list, along with a case of two-stroke oil and a permanent grin. With light weight and nimble handling, hooligan sound and just a wisp of blue smoke, here is a collectable machine that is begging to be ridden.

The auction is currently at the $4,000 mark, which is low dollar for a complete and original RZ. There is no reserve, so some lucky bidder is going home with the bike! To get more info, see more pics and get in on the action, click on the link and

 Well big fella, are you really brave enough to ride this beast?  A 750cc two stroke, in that frame, with those wheels?  Not on my to do list my friends.  I honestly can’t fathom what an untamed 750cc two stroke from the 70’s is like to ride.

This picture says it all.  Expansion chambers running amuck.  The sound must be something else.  I would think this thing would want to twist the frame into a pretzel when it comes on the pipe.

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 –
