Yes, another Yamaha RZ350 “King” Kenny Roberts Edition (’85)

Location: Ashville, North Carolina

Mileage: 3,439

Price: Auction, currently $4,200 with a reserve

There seems to be a run of Yamaha RZ350’s lately on RSBFS. Like for instance this one just posted by our fearless leader, Dan. Like the others, this one is a Kenny Roberts edition, a rare two-stroke sportbike brought to the U.S. market. And I’m sure everybody here knows about Kenny Roberts and his stellar career in Grand Prix racing. A true American racing legend. These are cool bikes and it’s great to see clean examples out there for people to take home.

Here’s what the seller has to say-

Beautiful low mileage Yamaha RZ 350 with 3,439 original miles. Bike has expansion chambers matched with Tommey mufflers and runs great. The paint and bright work are in excellent condition and the guages are clear and in perfect working order. Bike has on a set of new Dunlop Arrowmax tires. Please note the many detailed photos as this machine is in overall excellent condition and is a blast to drive.

And some more pics-

This looks to be a clean, low-mile example. The seller doesn’t provide a lot of description except to highlight to expansion chambers and  pipes. The rest of the bike appears stock and in good shape. You may want to ask more about the condition and the maintenance history so you know exactly what you’re getting into. Low mileage bikes are great but not running a bike (or car) can have issues of its own.

There are plenty of bids so far and these usually go in the $5k range. So we’ll see where it lands. But if you missed out the other RZ350’s recently posted or this one is near you, negating shipping, or you just like them,  then go check this bike out.

The Lost R1? Yamaha R1-Z 250

The Lost R1? Yamaha R1-Z 250

Where have these darn things been hiding?   What a solid looking bike: a two stroke twin wrapped in an eye pleasing package.  Simple yet sexy.  The RZ-1 is another in a line of Japanese domestic bikes that never saw the light of day on foreign shores.  That is kind of hard to imagine with the cult following the RZ350 has.  These were produced in 1991 and 1992 (I think) but would look  right at home in a dealership  in 2012.  Update the headlight, forks and swing arm and you are in business Yamaha.


This particular bike is located in the UK and has underwent a complete rebuild with custom paint.  There isn’t much to say, it just looks good.


From what I gather, the R1-Z uses the early  TZR parallel twin engine.  Being a domestic market bike they have the usual 45hp restriction.  I’m sure it could be unplugged with a little work.  Maybe without a fairing for protection you’d be happy with the 45hp.

To cut costs sometimes they’d go single disc upfront on these sort of models; not so with the R1-Z.


Come on Yamaha, work some overtime on direct injection and you are in business with this bike.  With the popularity of naked bikes and the built in RZ350 crowd I bet you couldn’t keep them in the showroom.

Damn, I like this bike!  Check this one out with a TZR swing arm and upside down forks.

Since you can’t count on Yamaha,  you might just have to snap this one up at auction.



Here is a Japanese test of a modded and standard R1-Z

It’s good to be King: 1984 Yamaha RZ350 Kenny Roberts Edition

For Sale: 1984 Yamaha RZ350 Kenny Roberts Edition

Located in North Carolina sits this beautiful survivor: a 1984 Yamaha RZ350 in the “King” Kenny Roberts colors of yellow and black. These RZs were the last factory two strokes to make it into the United States, and not many survive in decent condition. Because these bikes in stock form could not quite keep up with the 550cc four strokes of the era, the RZ did not sell well. Those that did were either raced, or thrashed and ratted out.

The most popular modification to “wake up” the performance of an RZ is the use of aftermarket expansion chambers. The stock pipes were heavy, restrictive units that contained catalytic converts in their centers – ditching these results in a healthy weight loss and healthy boost in power. Thus while collectors might seek a perfect bike with the original pipes, enthusiasts will want a slightly modified mount such as this. The difference in performance can be substantial.

From the seller:
Here is your chance to own a great classic bike. This is a 1984 Yamaha RZ350 Kenny Roberts edition in competition yellow. It has a 347cc, 2-stroke, liquid cooled YPVS twin engine and a 6 speed manual transmission. The bikes dry weight is 331 pounds and has a 5.3 gallon fuel tank. I bought this bike in 2007 and have kept it inside my temperature controlled shop only riding it here and there. It has only 8,254 miles and is in great condition especially for being almost 30 years old. This is a smooth bike and the only performance alteration being that it has been jetted for the dual pipe Toomey Racing exhaust. It has the single person seat on it and does not have mirrors. Cosmetically the bike is very sound as well, it has one very small ding in the gas tank which you can see in the picture and some missing paint from top of the right side engine casing. It would be tough to find another one of these bikes in this condition. The tray under the center stand is to protect the floor, not for leaks. If you have any questions or would like specific pictures feel free to ask. Thanks for looking.

I am only the second owner, I purchased the bike from the original owner when I bought it in 2007.

The Yamaha RZ350 was a 2 year bike in the U.S. After 1985 the two stroke party was officially shut down. Perhaps that is why these little RZs – despite not selling particularly well in the 1980s – have been consistently going up in value over the years.

The opening ask on this yellow buzz bomb is $5,500. While that sum would have bought you a very low mile, perfect example in years past, this is pretty much the going entry rate for the average bike. There is no word on if a reserve is set, so only time will tell if the price on this model ends up being on the high side. From the opening, however, this is pretty much a fair market ask.

For your chance to check it out, click on the link and jump over to the auction. Drool over the picks, imagine the ring-a-ding-ding of this little rocket coming on the pipe, and then drop back by to share your thoughts. Good Luck!

Be the King- ’85 Yamaha RZ350 Kenny Roberts Edition

Location: Acworth, New Hampshire

Mileage: 12,210

Price: Auction, currently $2,805 with a reserve

For all of you folks out there that secretly or openly lust after a two-stroke, here is a good answer for you. Don’t want to deal with getting a bike titled? And if you can’t, worried about getting your pride and joy confiscated by the two-stroke police? Well, then the Kenny Roberts RZ350 is a nice choice, as a rare two-stroke bike offered for street use in the US in the early ’80’s.

Although not imported into the US for very long, just three years, the reworked Yamaha was able to meet emissions standards and still provide a fun ride for two-stroke enthusiasts out there. It weighed 330 lbs, had disc brakes all around and you could take it home for $2,399. Back then.

Here’s what the seller has to say on this one-

I purchased this bike 4/09 with 11.230mi. 8/10 with 11.680mi. a new SPECII engine with a StageII upgrade was installed. This includes a new welded and balanced crankshaft, 64.5mm pistons, milled cylinder head, moderate porting, SPECII fiber reeds, 30mm Mikuni carbs.with a K&N 2 into intake, and SPECII classic expansion chambers. Additional work includes fork seals, upgraded steering stem bearings, #1 shift fork, EBC HD clutch, 16/40 sprockets, rear sprocket dampeners, and new tires. The fuel tank has been professionally repaired with the exception of the improper installation of the left fuel tank decal. This bike is in exceptional condition for its age.No rust. Mechanically flawless, though not aestetically perfect. The solo seat cowl has some minor cracks, the 2 up seat cowl is in excellent cond. The windshield has some cracking around the screws. Never raced and never down. The fuel system has never seen pump fuel. Any extra parts I have are also included. Thanks for looking and good luck.

And more photos for your consideration-

As the seller describes, this bike has seen some significant modification to the engine. In the auction there’s more detail on those mods in the Q and A. The bike also appears to have been very well maintained and cared for. The seller highlights some small cosmetic issues, specifically around the decal on the tank, small cracks around the windshield and seat cowl. You may want a little more detail on that, but it seems minor. Mileage is reasonable, especially with all of the engine work done.

All in all, this looks to be a cool ride that could satisfy your two-stroke desires. You could get on it and pretend your Kenny Roberts. If that works for you, go check this auction out.

Clean ’84 Yamaha RZ350 Kenny Roberts Edition

Location: Lincoln, Nebraska

Mileage: 4,730

Price: Auction, $8,500 BIN

Here’s a clean “King” Kenny Roberts edition Yamaha RZ350. Many of these have been featured here at RSBFS, being a rare US legal two stroke. Two strokes offer an exhilarating world of high revs, light weight and good power. Unfortunately, emissions kept them mostly out of the US. Yamaha’s YPVS system helped boost power, keep things clean and gain its import into the States. And then there’s also the fact that Kenny Roberts is an American racing legend, being the first American to win a Grand Prix.

Here’s the info on this machine from the seller-

This bike is one of my personal bikes that I must let go due to hard economic times, I will miss her.

This is a very low milage RZ350,  almost all original the upgrades are listed below. I bought this RZ from a customer about 4 years ago after we installed new rings, cleaned the power valves, installed new chain and sprockets and tires, went through the brakes and installed new brake pads. Since then I put around 350 miles on the bike.

This bike will start right up, run great for miles and miles, and will not dissapoint.

The professional pictures were taken of the bike before we installed the HVCcycle exhaust. It had AllSpeed exhaust at that time. The HVCcycle exhaust is a far better and lighter exhaust.


Race Tech Gold valves and race tech springs in the front forks. (spring 2011)

HVCcycle Performance Exhaust, (Fall 2010)

Carbs have a Dyno Jet kit and a K&N Y-boot air filter kit.

Bridgestone BT45 tires  about 350 miles on the tires and tubes

New o-ring chain, and aluminum rear sprocket. (same as tires)

New EBC brake pads, front and back.

The bike will be sold with a brand new battery, the one in the bike is a few years old.

What is wrong with the bike

There is one tiny dent on the front right of the tank about a half a dime size.

Any questions, give me a call.

We can help to arange shipping.  I will deliver for a small price as far as Kansas City, or Des Moines.  Or about 3 hours from Lincoln NE.  (small price is determined on how much gas it will take to get there)

If you Win, a $2000.00 deposit is due within 48 hours. the balance due on pick up or before delivery.  I will take credit cards for the purchase but the 2.8% fee will be added to the total.  

And the pics-

So the great news on this bike is that it appears to be owned by a real enthusiast that has a shop pretty much dedicated to the RZ and two strokes in general. With that comes lots of upgraded goodies on the bike and what appears to be excellent maintenance. Also, mileage isn’t that high either. The seller points out a small ding on the tank as really the only issue.

So now the price. At $8,500 BIN this bike is going for a premium. While the market is always difficult to read, usually these are around the the $5k mark. This looks to be very well maintained with good upgrades so it’s up to you to decide how far that goes.

Regardless, these a killer rides. Take a look and if it strikes you, place your bid.

Low Mile, Canadian, and Titled ’83 Yamaha RZ350

Location: Glendale, Arizona

Mileage: 1,558

Price: Auction, $5,700 BIN

RZ 350’s that came to the states were emblazoned with Kenny Roberts signature on the headlight fairing honoring the great American Grand Prix rider. However, the bike existed elsewhere in the world before it was introduced in the U.S. in 1984. This is one of those bikes. Of course this model still has the features you would look for in any two stroke – light and powerful.

Here’s some brief detail from the seller-

1983 YAMAHA RZ350

2552 Kilometers (1585 Miles)

Canadian bike


All original. Runs and rides great

Tires perfect, seat perfect.

No dents, scratches or scrapes

Maybe one of the nicest examples remaining.

Clean ARIZONA title

This motorcycle is sold as-is, where-is, with no warranty. I recommend having the motorcycle inspected before purchase.

All sales final. No returns

Payment to be made via direct bank to bank wire transfer or cash in hand. No other forms of payment accepted.

Payment must be made within 3 business days of auction end.

Shipping of the motorcycle after payment received is up to the buyer, but I will assist with pick-up once buyer has a carrier.

This motorcycle is for sale locally, therefore this auction may be ended at anytime due to local sale, as long as reserve has not been met.

And some more photos-

So I have to say that this bike looks Kah-leen. Certainly the low mileage has a lot do with that. Seller states it’s all original and runs great. It certainly looks really good and seems to have been stored well over the years. It’s titled, which is a bonus. The BIN price is right in there, especially for a low mileage, clean example like this.

I really don’t have much more to say. If you’ve been searching for one of these, I think this one would need a serious look. Fun or collector, it should fit the bill. Decide for yourself and make the jump!

Another “King” Kenny Roberts Yamaha RZ350

Location: Enterprise, Alabama

Mileage: 14,003

Price: Auction, BIN $4,600

We have seen a few of these recently here at RSBFS, and they are written up for good reason. Not only are they a US import two-stroke (a hard thing to come by) they are also the signature series bike for “King” Kenny Roberts, a Grand Prix racer that stormed onto the scene and dominated from the start. King Kenny stepped up and interrupted european dominance in Grand Prix racing and was the first American to take the title. A true legend. The bike itself is the opportunity to own a great performing two-stroke with a stellar racer’s name on it.

Here’s some information from the seller-

1985 Yamaha RZ350 YPVS.  2 cylinder, 2 Stroke water cooled sport bike.  This RZ is in nice shape and runs well, 14,000 original miles. 

.  If you are considering adding an RZ350 to your collection than you want a 1985 as opposed to the 1984 model.  The 1984’s had a failure prone ignition system which was sorted out for the 1985 model year.  This RZ is in nice condition and runs well, has never been dropped or wrecked.  Everything works as it should including turn signals. Yamalube oil injection system still in use with new pump.

This RZ has been well taken care of and is currently registered and titled in Alabama.  Many new parts including new tires, new brakes, new fork seals, new trailing arm bushings.  Complete Top End engine rebuild including new pistons done 1500 miles ago.

Many performance parts:  SPEC II exhaust chambers, Thunder Jet stage III Carb jet kit, K&N Y boot intake filter system, TDR Carbon Fiber Reed valves, Stainless Steel brake lines, 16 tooth front sprocket, Corbin solo style seat.

Stock parts included:  Stock exhaust system, Stock black seat, Stock 17 tooth front sprocket, Stock horn set.

Flaws: Front of gas tank had fuel spilled on it while paint was still fresh, it was touched up but is visible.  I took a close up picture so that there would be no surprises.  One scrape on the left side of the upper fairing.

The maintenance on the bike seems to be fairly thorough and the seller highlights changes to the bike along with stock parts included. To me this shows the seller is aware of the potential value of the bike in its original condition. While many bikes benefit from modifications, collectors are going to be more and more picky, especially as values climb. The seller highlights the flaws that exist too, which I also like to see.

Here’s some more pics-

Considering the maintenance performed on the bike and the mileage, it seems the sellers BIN price of $4,600 is right in the ballpark. You may want to get some more detail on the issue with the paint on the tank, but otherwise it looks to be a clean bike.

I stated my case as to why I like these bikes and why they earn their place here at RSBFS. It’s up to you now. If you like what you see, make a move and make the jump!

Legal Smoke: 1985 Yamaha RZ350 Kenny Roberts Edition

For Sale: 1985 Yamaha RZ350 Kenny Roberts Edition

Is it just me, or has this year just flown by? It is September already. The kids are back in school and in many parts of the US the riding season is wrapping up. Pity those Californians, however. Their riding season still has months left to go. Too bad they can’t register really cool bikes like gray-market import smokers. Fortunately for the Golden State, this good looking RZ is ready to go with CA title!

This 1985 RZ350 sports some nice add ons that really help make the bike. The factory RZ came only with the bikini fairing (yellow bikes had King Kenny’s signature in ’84, but both the yellow and the white/red bikes had it in ’85). This bike has aftermarket lowers – nicely color matched – which help clean up the silhouette. The fork brace, also evident in this shot, is another necessary addition for when the road turns twisty.

With only 13,500 miles on the bike, this bike is right in line with other RZs we have seen. The Toomey piles are the real deal, and the K&N filter (and requisite jetting changes) really work together to wake up the performance of this little buzz bomb. The rear sets might be more extreme than some prefer, but the stock RZ has the rider sitting a bit upright – comfortable, but hardly in line with the intent. If you scrape a peg on this bike, it might be because you are sliding down the road! The clubman bars, evident in this photo, also appear to be an aftermarket item.

For Sale:
1985 YAMAHA RZ350N Kenny Roberts Edition. Excellent Condition. Always Garaged. Original Paint Still Shines Like New. Full Fairing, Raask Rear Sets, Toomey Pipes, Front Fork Brace, K&N Air Filter. Carburetors Recently Professional Cleaned and Tuned. Runs Flawlessly. Only 13,452 Original Miles(may have a few more by the time the auction ends).

The Only Flaws On This Bike that I Know of are as Follows…

Standard Road Debris Paint Wear on Bottom of Frame.

Tiny Touched Up Ding in Fuel Tank from Old Stock Mirror.

Oil Tank Mounting Tab on Frame and Plastic Tank Broke Off Clean Many Years Ago(oil tank sits in place by the hoses anyways so I never bothered to have it welded). You Can Set the Tab Back in Place on the Frame and Barely See the Crack so that is Why I Say it was a Clean Break. Another Oil Tank is Included with the Bike in Case the Buyer Wants to Fix this.

Small Touched Up Area on Top of the Rear Fender.

Minor Spider Cracks Around Some of the Screws on Fairing.

Exterior Rubber Fork Seal Covers Have Some Cracking from Age.

The Bike is Very Clean and You Have to Look Real Close to See any of the Above. The Spot on the Seat in the Main Photo is A Spec of Dust on the Camera Lens and Not a Flaw on the Seat. There are no Rips, Tears, or Flaws on the Seat.

This Bike is Street Legal in all States Including CA. It is the Last Street Legal US Two-Stroke Manufactured.

Don’t Miss this Rare Opportunity to Own a Clean, Low Mileage, Red/White Kenny Roberts RZ that is Sure to Increase in Value Over Time.

I like a seller who is not afraid to show his cards. In this case, the flaws are openly noted. I would prefer a few more photographs (preferably taken in better light), but you can’t fault the seller for sharing what he knows.

There are also a few items not mentioned here that are worth looking at. The turn signals were not originally flush-mounted – stockers sat on posts front and rear – so these have been modified. The seller also mentions a dent on the tank caused by the stock mirrors, but the stock mirrors were not bar-end mounted like the current set. That leads me to believe that when the bar-end mirrors were mounted somebody did not account for clearance between the mirror or mount and the tank. Minor, but a detail nonetheless.

Pricing on this RZ is right in the ballpark: The opening ask is $3,750 (a very reasonable starting point), and the BIN is set at $5,750. The BIN number might be a touch high for the market, but for someone who wants a titled smoker in great shape it is not an absurd price.

For your chance to check out this CA legal two stroke, click on the link and jump over to the auction. These RZs continue to be very sought-after motorcycles, and values may well rise in the coming years. Don’t forget to tell ’em you found it on RSBFS!
