Muscular Monkey Bike: 1989 Yamaha YSR-50

This 1989 Yamaha YSR-50 isn’t anywhere close to perfect, but it is a nice, functional example of what was a very popular — if slightly weird — part of Yamaha’s past. They might be tiny, but modifications abound for the 7 horsepower, 50cc two-stroke single, which will raise the top speed above the original 38 mph. Lots of up-and-coming road racers in the late 1980s and early 1990s turned their first laps on YSRs, and you’ll still see them being thrashed in series like M1GP.

The seller’s description is scant on details, but it has its share of niggles, including blinkers that come on but do not blink. Many of the metal parts have age blemishes on them, but appear to be sound. The right side fairing has some rash, so somewhere over the bike’s 1,800 miles it has at least been dropped, if not actually crashed. The bike will require some work to be a museum piece, to be sure, but as these little rippers get rarer, their popularity is going up.

From the eBay listing:

Yamaha ysr 50 very nice ,not mint .but very nice rider 1,807 miles new battery runs very well every thing work .but the blinkers don’t blink..titled in my name ,all stock Oem bike view pictures

We have seen nicer versions of the YSR sell for double the opening bid on this auction, though there has been little activity on this auction thus far. If you’re looking for an entry-level racer, a funky rider or an easy project, this thing could fit the bill.

Mighty Mite: Warmed up 1988 Yamaha YSR 50

With a wheelbase just over three feet, Tonka truck sized wheels and a wet weight that sneaks in four pounds lighter than I am, the 1988 Yamaha YSR 50 set out to make the very most out of the smallest package possible. They were, for better or worse, glorified mopeds, albeit with proper clutches and five-speed gear boxes.

With working lights and turn signals, they were road legal from the factory, sort of like a 1980s Honda Grom; a nimble city bike that dared you to drag a knee at 30 mph.

This example is not the cleanest we have ever featured, but it packs a custom exhaust, 63-cc big bore kit and a hot carburetor. Those little hop ups should put the 50 mph top end listed on the white-faced speedo within the realm of possibility. Or at least imagination.

From the eBay listing:

Selling my 1988 YSR 50. Its the rare blue and yellow (some say rarer than the black and white one). i have had this bike for a loooong time. Super clean and runs like new. here is a list of mods:

50cc engine bumped to 63cc with mikuni carb and cylinder ported. Boyseen reed cage
Team Calamari Racing exhaust
Chrome frame and swingarm
Fox rear shock with remote reservoir
Team Calamari Racing second fork spring
1/4 turn throttle
Douglas aluminum wheels with Dunlop tires

I do have a bunch of original parts (like wheels, carb, airbox, etc.) that will go with the bike. Bike has clean title and is street legal. Bodywork is near perfect with the exception of the front upper fairing – one of my workers dropped it and cracked the fairing. I do have another original blue one that will go with the bike. You will not find another in this color in better shape. Send message with contact info for more pics and such. paypal is

I will help with shipping but retaining the carrier will be the buyers responsibility. i can get it on a palate and strapped down for shipping. If needs to be crated will be $200 extra

For a true collector, the upper fairing could use some work, but the seller says a good matching one is included. Added to that, the solid aluminum wheels aren’t doing a whole lot for unsprung weight, such as it is, but they sure complete the look.

The auction only has a couple days left, so move fast if you want in. Ever ride one of these? Let us know the ins and outs in the comments below!

Pocket Rocket – Mint 1987 Yamaha YSR 50

Mint 1987 Yamaha YSR 50 on eBay


One need only look at the price and the bidding activity to know that what these little YSR 50s lack in size, they make up for in desirability.  In barely 24 hours on eBay, the auction has pushed past $3600 with 19 bids.  I would expect that it could exceed $5000 which would be a very strong selling.  Yamaha produced the YSR 50 from 1987  through 1992.  It featured an air cooled 500cc two-stroke engine, five speed transmission and would hit almost 55mph with a lightweight rider.  YSR 50s have a strong cult following, with owners who collect, restore and race them.  This 1987 represents the first year of production and is the nicest one we’ve seen in a very long time.  With all of the stock bits intact or included, extremely low mileage and nearly flawless condition, the seller may end up pleasantly surprised at the final price.


The more you look at it, the more you realize that it’s probably the nicest one available.  A great many of the YSR-50s were simply viewed as toys and were ridden hard and suffered a lot of abuse.  They pop up for sale here and there, but they have almost always been crashed and rebuilt, often painted in whatever garish House of Kolors chameleon paint the owner had left over from a stretched and slammed Hayabusa paintjob.  This one is a great reminder of how cool they looked in the original colors with a nostalgic nod to the Marlboro Yamaha GP bikes of the 80s and 90s.


The seller has some good information on the bike that can be seen in detail at the auction listing here: 1987 Yamaha YSR 50 on eBay

First year YSR 50 that has 419 original miles in like new condition and all original. It runs great, starts on first kick, shift fine and everything works. The story with this bike is that I purchased it from a gentleman I work with who was a Yamaha dealer in the eighties. He personally purchased the bike and rode it for 407 miles before storing it away. He replaced the exhaust with a Toomey and I have the original Exhaust in the Toomey box. It includes the original manual, never used tool kit and a clear title in my name. The bike is in showroom condition and does not have any corrosion with beautiful paint. The only thing is that when he stored the bike he never drained the gas. Therefore the tank has gas tarnish in it. I cleaned it several time and have a paper filter on the gas line and it looks clean. I did thoroughly clean the carburetor and purchased a new OEM petcock. It has a new battery, new OEM air filter, transmission oil and fork oil replaced.

Shrinking Economy Special-50cc Madness: GSX-R, YSR, NSR (Sorry No Kawi)

Shrinking Economy Special-50cc Madness:  GSX-R, YSR, NSR (Sorry No Kawi)

This is my tribute to our “sluggish” economy.  To go along with smaller salaries, smaller portions at restaurants and (my pet peeve) smaller tubs of ice cream: I’ve put together a few smaller bikes for sale.  A search around the internet revealed some nice low mileage bikes out there if you have a thing for cc challenged bikes.  I tried my damnedest to find small Kawasaki but with no luck.  There were a couple AR50’s out there but they were serious project bikes.

First up is a little GSX-R50 on Ebay.  It looks to be in good shape other than the lower.  It appears to have been deformed from heat.  A definite sign of some other problem as that obviously should not be happening.

This is Suzuki GSX-R50 Japanese mini-bike. The bike runs excellent and is in good shape except the bottom of fairing is distorted possibly from heat see pictures for details. Disclaimer: The bike doesn’t have an odometer so mileage is unknown. Also, I am guessing on the year of this bike. Local pickup only or buyer makes alternative shipping arrangements. Let me know if you have any questions.

is nearing it’s end so be sure to jump in soon if you have an interest.

Next up are a couple of super clean NSR50’s, well one is actually brand spankin new.  Remember the NSR’s were track only bikes; where with the GSX-R and YSR you can terrorize the neighborhood.

 Honda NSR50 imported from Japan for only one year.
Extremely rare only around 4000 imported
interested in trades for jet boats and sea doos specifically but am also interested i nquads dirtbikes other streetbikes, motards or sided by sides, maybe even a nice car or truck
price is negotiable

The seller is asking $2,500 and as above he is open to trades and offers.  Check it out on Columbus, Ohio Craigslist.

If you don’t want an NSR touched by some heathens hands then the next one is for you.


2004 Honda NSR50 R
Stock Number: HR10027

BUY NOW and SAVE $$$

$2,599.99 plus fees, doc, tax, and license

This one is at a dealership in California.  Check it out on Sacramento Craigslist if you are interested.

For you Yamaholics I found this tidy YSR 50 in my backyard; Atlanta.



If the Wayne Rainey in you wants this one, it can be found on Atlanta Craigslist.

Obviously none of these bikes are as rare as most of the bikes we post here on RSBFS but ones in good condition definitely are a rare find.  Little bikes like these were usually treated as toys and time and lack of up keep has gotten the better of them.
