Baby Bro – 1988 Yamaha YSR-50

Yamaha’s entry in the pocketbike derby was the YSR-50, easily loaded in the back of the minivan at 165 lbs., but tons of fun.  This example looks complete and original with a single-year paint scheme and California title.

1988 Yamaha YSR-50 for sale on eBay 

A bit like the supersport sharing specs with a superbike, the YSR50 is the 49cc version of the YSR80, and because it was easier to license, more popular.  Seeming to share most things from the -80, like 12-inch wheels, “Do Not Sit Here” pillion and front disk brake, and also inherited the 5-speed transmission.  From a couple of blocks you could be excused for thinking it might be an RZ500, and mostly showed up in red/white with the blue just available in 1988.

Occupying just a corner of the garage, this YSR50 has been nicely protected and appears to have all its DOT required equipment.  Banana windscreen and a Toomey pipe are the only visible mods, and with under 1,400 miles it might not need much to be a runner.  Parts and upgrades appear to still be easily available, with funky mirrors that hold a force field over the fairing.  Notes from the eBay auction:

Clean title, great bike.  Yamaha YSR 50 blue and gold Toomey exhaust , excellent bike, original manual book, if you’re looking for a clean YSR 50 that hasn’t been taken apart and it’s in perfect shape this is the one, no dings or scratches anywhere on the bike all original.

Of course the price of that condition and lack of “upgrades” is an ask that a recent supersport would be happy with.  But there won’t be another like this pop up for a while.  Maybe there’s a more generously sized racing blue Yammer in your garage that this 50 would look great next to.

Special and Rare: 1985 Kawasaki KR250 GP Replica

With an appreciative nod to fellow RSBFS contributors William and Doug for the find and the post title, today brings us a bit of two stroke holy grail action: the Kawasaki KR250. Blessed with the same name as the GP race bike, the street-going KR250 shares no parts with the competition platform, yet the roots are strong, deep and unmistakable. We tend to find quarter-liter smokers from Honda, Yamaha and – to a certain extent – Suzuki on a far more regular basis as the more rare Kawasaki, making the green machine the most rare across the Big Four brands. But don’t let the lack of showroom success lull you into thinking the mean green machine was an also-ran in this category; the KR250 is every bit the equal of the more common two-stroke mob, and more!

1985 Kawasaki KR250 GP Replica for sale on eBay

The spec sheet for the KR250 calls for 249cc of tandem-twin goodness. What the heck is a tandem twin, you ask?! Unlike a parallel twin (cylinders side by side) or a v-twin (cylinders opposed at 90 degrees, typically), the tandem twin is more like a pair of 125cc engines with one mounted right behind the other. They are separate, but share a common crankcase and crank outputs are synchronized via gearing (not unlike half of a Suzuki Gamma square four). Think of this engine arrangement as having all of the width benefits of a v-twin, while also having optimal mass placement in the chassis, forward and low. Fed by two carbs breathing through rotary valves, the KR250 pumped out 45 stock ponies at 10,000 RPM.

From the seller:
Another super cool and ultra rare 2T coming out of my collection. This was a factory GP replica of Kawasaki’s 250GP racer, centered around a tandem twin cylinder two stroke with rotary valve induction and a close ratio 6 speed transmission. Top of gas tank is signed by the original designer of the bike and clear coated to preserve the signature. Also includes framed press release which is the last picture in the gallery above. This was a Japanese domestic market only release? and may be the only one in the US…or North America?

Bike has a clean and clear California title ready to sign over…whoa!

More from the seller:
Mileage stated above is converted from Kilometers on the speedo. Actual shown is 43,390km’s. Overall pretty darn clean and in great shape. I rode it a couple of hundred miles when I first got it, then fogged it and drained the tank and carb float bowls to put in my collection inside my home. Rides peppy and super lightweight.

The Bad: The bottom right aluminum silencer has some road rash underneath, but I’m suspecting that it came off another bike because I see no other rash or damage anywhere else including the peg, bodywork, etc. I do have some aftermarket Japanese hand made expansion chambers for it new in the box available for sale to the winning bidder if so desired. Remember, this is almost 40 years old and does have some mileage on it, so don’t expect a museum piece, but then again, try and find another one, especially with a CA title! These engines were well known for their extreme durability and longevity though.

More from the seller:
Compression has always felt a little low to me when kicking it over, but it always started first kick cold, but took forever to get up to full operating temperature as the cooling system is way overbuilt, like everything else on it. Starting with a low starting bid so everyone can get involved. Once there are bids, it goes to the highest bidder absolutely! I will NOT end the auction early so please do not ask “what will you take for it now” or “do you have a buy it now price”.

So here we have a *very* rare 80’s two stroke – which was a Japanese home-market only type of affair. Add to this rarity the fact that it has been imported into the United States AND has a current California title (all but impossible for mere mortals) and you have what adds up to be something that is truly special and rare. The bike itself is located in Utah, but chances are good that with that CA reg it can be moved practically anywhere. We have seen in the past the CA reg can add significantly to the value of an import, so it will be interesting to see how this one fares. Opening bid on this one is a cool $10k, but that should be a no-brainer considering the rarity and what other bikes are going for in the marketplace today. Check out all of the details here, and Good Luck!!

Back in Black… and Yellow: 1984 Yamaha RZ350

Since the world appears to be going crazy with collector prices on RZ350s these days, let’s take a look at another candidate to see what is available in the market right now. The emphasis being what is in the market right now, as in what the current market will bear. And that is the maddening world of collector bikes; it makes no difference that you couldn’t give away an RZ 10 or 15 years ago, or that you could scoop up a top condition bike for under $5k. Today the market on RZ350s is pretty strong, and sellers are expecting more of the same. Thus, for your perusal, a very clean and relatively low mileage example of a 1984 RZ350, mostly unmolested save for some aftermarket Allspeed chambers (which surprisingly appear similar to the stock cans in silhouette).

1984 Yamaha RZ350 for sale on eBay

From the seller:
This is a NO Hidden Reserve Auction… highest bidder will Win!

For sale from my collection is one of my most prize possessions… a 1984 Kenny Roberts Edition RZ350L with 6,134 miles! Downsizing is my motivation and if this doesn’t sell, it won’t break my heart… I know I can’t replace it as these low mile bikes are gobbled up by collectors as one of their most prize possessions.

I purchased this bike out of state in Nov.2005. Even then, low mileage bikes were hard to find. The seller said it was stored and not ridden for almost 15 years and that it was then “refreshed” at a Yamaha Dealership with the request to make it “Run Like New” (as listed on the service order). The service bill was over $1,100 and included coolant system service, carbs, brakes, fluids and complete factory adjustments and lubrication. Some of the parts included 2 new Bridgestone Battlax BT45 tires, brake parts and pads for re-build, Air Filter, Spark Plugs, Carb parts, cables and oil.

More from the seller:
Since purchase, I barely rode the bike but it rode and ran fantastic. Incredible power, handling, braking and simply crisp. Pipe is not super loud and sounds really nice. That was a very busy time for me and it wasn’t long after that I removed the tank and prepped it for storage in my climate controlled garage along with my other bikes. I have not started or rode it in years so it will need to be gone through again should the buyer decide to ride it.

The bike is completely stock with exception of the Vintage Allspeed expansion chambers, New Bridgestone tires (at the time I purchased) and brake pads.

I hope the photos speak for themselves but I think the bike is in Excellent / Very good condition for a bike of this age. There are a couple of blemishes on the tank you can see in the photos but no major dents. The blemishes are just scratches and the previous owner used touch-up paint to repair. I believe you can take this to a professional and greatly improve the appearance. The one close-up photo is the worst spot with a small nick and is ever so slightly dented about 1/16” deep not quite the size of a dime. Underside of the tank is super nice & inside of the tank is also really nice. Just flash surface rust but it has been sealed and stored empty all these years. Overall paint on the Bike is also very nice with only minor imperfections you can see in the photos. Chin spoiler has no cracks and also really nice. I included a close-up of the front fork seal areas which look like new… no nicks or corrosion and I did not notice the seals leaking any fork oil. Brakes still seem to work fine and did not stick while I moved the bike but the fluid should be replaced again. Pipes still have the original paint and there is a shallow dent in the lower part of the pipe near the foot peg you can see in the photo (pic #9).

More from the seller:
I’ve tried to show as many photos as possible even with the tank & seat removed and underside. The seat by the way is in mint condition, soft and absolutely no cracks or tears. Chrome on the rear grab bar is smooth & great.

The bike comes with the original owner’s manual, original key and a copy of the service order the previous owner gave me. It still has the original Tool Kit. No battery as it was removed for storage and gave up the ghost long ago.

If the winning bidder is interested, I have an original vintage set of Toomey Pipes in near mint condition and a very nice Black / Yellow Corbin “Gunfighter ” Seat I will offer for purchase after the sale. I prefer to keep them both but will offer only if the Winning Bidder is interested.

The pictures show a very clean example of the RZ; used for 6,000 miles and change, but certainly does not appear abused. Corrosion and weathering is minimal, and while there is the noted mar on the tank, the rest of the bike looks to be much like it came from the showroom. This No Reserve auction has a starting price of $12,500 – which is actually pretty reasonable given the condition and market craziness. The last RZ we posted (here) has been bid up to just under $12k at time of writing, with a BIN of $18,500. This bike starts at $12,500 with no reserve, and $15k is very likely given recent pricing trends. You don’t have to love the bull market if you are a buyer, but what do you think of the bike? Check out all of the details here, and Good Luck!!

The Year That Was: 1985 Yamaha RZ 350

Really a bike that needs no introduction, the Yamaha RZ350 had a brief couple of year fling in the States until the EPA shut them down for good. Today’s clean looking 1985 model has been mistakenly listed as a 1984 – however unless you lived in California, the differences between the years were minor and largely cosmetic (for CA residents the years available were cut short as well). Let’s take a deeper dive!

1985 Yamaha RZ 350 for sale on eBay

When released in 1983, US riders were once again able to unleash the ring-a-ding, popcorn sounds of the ubiquitous Yamaha parallel twin. In stock form the RZ was decently potent, although it struggled to match the pace of the 550cc middleweights of the same era. Part of the struggle was due to the concessions made to noise and emissions. Most bikes were quickly modified by adding proper expansion chambers (adding performance and shedding serious weight). Once jetting was dialed for the upgraded pipes (usually accompanied by replacing the restrictive airbox with pods), the buzzy 350 was transformed into a hive of angry bees that could run ring-a-dings with four stroke stockers.

From the seller:
1984 1985 Yamaha RZ 350 Kenny Roberts addition, well taken care of Beautiful clean condition, much cleaner than most, stored in a clean controlled environment, adult driven its entire life, I have original exhaust if you would rather have it then the Toomey chambers that I just put on it last summer, I also I have the original seat or the solo Corbin seat whichever you would prefer, runs like new with rebuilt engine just to freshen things up, was not broke or blown up, no rusty gas tank issues, new tires, new chain and sprockets, this is a running bike with clean title in hand, located in Michigan, local Ann Arbor Michigan pick up or I can help with shipping at your cost rwarrs@msn.com for any questions you may have

When you consider the condition of this particular bike (including the near stock appearance), it is hard to fathom that it has nearly 22,000 miles on the odometer. Clearly someone cared about this little smoker. The seller notes an engine rebuild – which is an excellent idea for a 37 year old two stroke, and much less involved than a similar task on a four stroker. No details on exactly what was done, but one would imaging rings and seals for starters, and assuming that a refresh was all that was needed.

Like everything else in our modern life, the price for a decent RZ350 is getting more and more expensive. This particular example shows very well, and has been bid up over $9k very quickly. That is only half way to the Buy It Now number of $18,500, and there is a reserve still in place. Given the way this bike looks, it might just get there before this auction is over. Check out all of the details here, and then jump to the comments and share some RZ love. Unlikely to ever go through a major recession, the RZ350 will continue to climb at or above market provided that the condition is as excellent as this one seems to be. Good Luck!!

500cc, And Only 800 Miles: 1986 Suzuki RG500 Gamma

In the last couple of years there as been an undeniable increase in demand for 80s and 90s sport bikes.  Collectors are keen to achieve childhood dreams and this era motorcycle has seen a sharp increase in pricing.  Another trend has been that the highest demand is for bikes with the lowest miles.  There have been a few notable sales of brand new, zero mile 30 and 40 year old motorcycles recently.  This 1986 Suzuki RG500 Gamma is titled in CA and shows just 800 miles.

The tree production years saw 9284 of these 500cc, two strok, twin cranked, square four cylinder machines made.  Many were raced, or just well used.  It is uncommon to find a clean example, and even less rare to find one already in the USA.  This bike also has a California title, that will certainly widen the appeal.

Factory rated at just under 100hp and rev’ing to almost 12k RPM, this was an serious performance machine in the day.  Sub 11 second quarter mile times are still fast in the automotive world today.  There were many outlets to modify these bikes, and some options could net almost 120hp.  Weight for the RG was reported to be in the 400 pound range

From The Seller’s eBay Listing:

A near perfect fully tuned Suzuki RG500 Gamma 1986 model. Only 800 original miles and still on the original tires. Sold new in California this Canadian Spec bike spent its entire life with one owner until his passing. In a twist of fate the original importer who sold it got a phone call and bought it back. He had it fully serviced and then help it 5 years. The bike has a California title on non-op registration. Sold with a bill or sale and the pink if you so desire to register it. It came with the manuals tool kit and a full assortment or spares like a head gasket set and the stock Canadian turn signals and the rear seat. The bike currently has the euro turn signals on it. One small stain on the lower right corner of fuel tank from something leaning on it looks to be a rust stain. It’s reported the owner road the bike one summer then put it into his collection and never road it again. Great article about this motorcycle in pictures. Or Google Carrillo Suzuki RG500 Gamma.

Commanding a $60,000 Buy It Now price, this bike is priced aggressively.  But with so few miles and preserved in stunning original condition there are no comparable bike to benchmark pricing.  This truly is a case that the seller can ask any price and hope to find a collector that wants to add one of the nicest RG500s to their garage.

Odd that the seller used pictures with arrow watermarks for the listing, and did not provide detailed images of the noted tank stain.   What can clearly be seen is that this is a very clean example and includes many extra parts and details that make this package very appealing.

Featured Listing: One-Owner 2000 Cagiva Mito 125 with 667 Miles !

Update 1.24.2022: This bike has SOLD to an RSBFS reader. Congratulations to buyer and seller!


Check out the Bimota KB2 Laser that Shaun is also offering! -dc

From the Seattle area’s Garage Assassins, today’s Feature is a micro-giant, 125 cc cranking out 34 hp, weighing just 284 lbs. and looking for all the world like a Ducati 916 !  Always in a collector’s hands it has just 667 miles, all DOT equipment, and current registration.  We’ll let Duncan pick up the story from here –

2000 Cagiva Mito 125 for sale

The 2000 Cagiva Mito 125 boasts a maximum power output of 34 horsepower and 23 Nm of torque from its liquid-cooled, two-stroke, 125cc, single cylinder powerplant that was mated to a six-speed manual transmission. 284lbs. 3.4 Gallon capacity. Legendary designer Massimo Tamburrini re-styled the bike in 1994, giving it a knife-edge fairing, winged tank and monoposto seat fairing reminiscent of the Ducati superbike. Massimo Tamburrini went on to Ducati where he designed the 916 Ducati. This bike has many of the very same design attributes in a smaller package.

This entry-level machine boasts features such as a two-piece, dual seat, a full-fairing with a small, adjustable windshield, die-cast aluminum wheels, an analogue instrument cluster, a suspension package composed of a 40mm Marzocchi telescopic front fork and an adjustable mono-shock in the rear, a disc braking system both in the front and in the rear and a paint and graphic scheme inspired from racing
motorcycles.

This special find is not even broken in yet. We still have in the box a factory upgrade package. Air intake, special jets for carburetion, rear sprocket plus an exhaust upgrade, still in original packaging.

Duncan asks $14,500 $11,400 for the 2000 Mito, and can be reached by email sennaducati79@gmail.com.

This 916 Ducati look alike is a Cagiva Mito 125 2-stroke, the same type of motorcycle that Valentino Rossi started his racing career on at a young age. Back in the day they had a 125cc class of highly modified 2-stroke street bikes for upstart racers in Europe. Cagiva was the bike. Cagiva even sold an entire massive hop up race kit to convert these little rockets into race bikes.

This one owner gem has never seen rain, never down, properly stored in a climate-controlled man cave filled with a proper collection of amazing Italian motorcycles. Owned and maintained by a skilled knowledgeable rider of many years. The bike has recently had a complete proper nut/ bolt go through. Runs perfect and strong. If you plan on riding versus display, we recommend newer tires. The tires are not cracked or damaged, just not as fresh for your riding safety.

Now just over twenty years old, this perfect Mito 125 might be a singular opportunity for the next collector.

Duncan offers assistance with worldwide shipping and asks $14,500 $11,400 for the 2000 Mito, contact him by email sennaducati79@gmail.com.

Older Display Model: 1979 Yamaha RD400 Daytona Special

To start this post off on the right foot, let’s make it clear: if you win this auction and do nothing, you will have won a static display. Seller claims this 1979 model of the last of the RDs is mint – and cosmetically it does appear to be so. But after sitting quietly since 1986 (for the math challenged that is 36 years of inactivity), some mechanical effort may be required to wake the beast within. Is that worth it? Well, yeah, it is. After all, this is a freaking Daytona Special, and Special is more than just a name.

1979 Yamaha RD400 Daytona Special for sale on eBay

The final year of the RD400 series, the Daytona Special – or “F” model in Yamaha nomenclature – was already a throwback in a new world order of four strokes. Still, the venerable parallel twin had some tricks and some teeth. Updates with disk brakes (single disk front and rear) and industry leading cast wheels, the 365 pound (dry) RD was pushed along by 44 angry bee horse powers. Active riders were rewarded when keeping the tach above 5,500 RPM and on the boil, where the RD exhibits some of its race-bred DNA. Autolube oil injection keeps the two stroke happy while eliminating the gas station shenanigans of oil bottle guesswork. All told, this was the most up to date, refined and “last gasp” serious road-going two stroke available in America before the brief-lived RZ350.

From the seller:
The RD400 has been inside our dealership on display since August 1986. It is in mint condition for a 43 year old motorcycle. It does not currently run/operate. It has a clear Texas title.

The bike comes with 1 key, an original Yamaha brochure, and 2 (Daytona Special 400) stickers/decals.

We can assist with shipping if help is needed.

Well, not really that much info available. It is not clear if the seller has tried to get the bike running and given up, or if this is more of a push-it-out-the-door-as-is affair. Thankfully smokers are not that complicated, although I would firstly be concerned with whether the motor turns over (i.e. pistons/rings not seized in the barrels), followed by fuel system. If all that passes muster, the thing should run. From there a leak down test to check the crank seals is in order; no use getting it running just to have it run lean and seize up at an inopportune moment. And finally, be sure and budget in a new set of sticky rubber to take advantage of what comes next. Is that worth the effort? The Daytona Special is a pretty special bike, both mechanically as well as historically. To find one in such showroom condition with only 3,000 miles on the clock is rare indeed. Check out all of the details here, and then be sure and jump back to the comments and share your RD thoughts and experiences. Good Luck!!

Display Model – 1984 Yamaha RZ350 with 1,841 Miles!

Besides being a midsize beast with 52 hp and under 400 lbs., the RZ350 was distinctive having actually been offered in the U.S. for a few years.  Today’s Kenny Roberts commemorative has been on display at the dealer since your cell phone was 2G and looks extraordinary.

1984 Yamaha RZ350 for sale on eBay

Trying to modernize a venerable engine design, Yamaha threw the book at its 347cc two-stroke, including water cooling, oil injection, their power valve port system, air injection, and a lot more for California-bound bikes.  Power delivery was peaky, with relaxed acceleration under 6,000 rpm, and whoa Nellie ! from there to the 9,500 redline.  Elsewhere it looked its $2,400 MSRP with conventional steel frame, and suspension with pre-load adjustment only, though the triple disks, alloy wheels, and sharp bikini fairing were nice touches.  Almost too obvious to mention, the classic livery celebrates the multiple AMA number 1 and first American GP champion, who went on to become a race bike builder and GP team manager.

After thirty years on display, this RZ is a fantastic piece but not ready to roll anywhere but into the workshop.  It must’ve been well back from the velvet ropes, since there’s not a scrape or bruise to be seen.  Every picture shows off its trim lines, period expansion chambers look the part, and the vapor canister missing from the engine bay seems to indicate it’s a 49-state model.  RSBFS contributors raised a collective eyebrow at the seller’s use of the word “mint” on a non-running bike, but considering it’s pushing 40 the condition is remarkable.  Just a note accompanies the eBay auction:

The RZ has been inside our dealership on display since 1991.  It is in mint condition for a 38 year old motorcycle.  It does not currently run/operate.  It has a clear Texas title.

The bike comes with 1 original key, the original owners manual, and an original Yamaha brochure.

Nothing like a stock showpiece to set the bidding on fire, and with a whole week to go this one will probably set some 350cc records.  Tires will stay wooden originals, but a few things could be shined up here and there, and maybe clean out the fuel system for the long term.  Then it’s probably off to a private museum for this RZ350, though it had a nice run in the dealership window.
