More JDM Madness: 1989 Yamaha TZR250 3MA for Sale

Warning!

This post is in our archives. Links in this post have been updated to point to similar bikes available to bid on eBay.

1989 Yamaha TZR250 3MA R Side Rear

With many lightweight sportbikes now flirting with the edge of 25-year import rules, I expect we’ll see more and more bikes like this Yamaha TZR250 up for sale in the next couple of years. Road and track weapons designed to keep pace with Honda, Suzuki, and Kawasaki in the viciously-competitive 250cc class, the 1989-1990 TZR250 featured an interesting reversed-cylinder two-stroke parallel-twin, with the carburetors mounted on the front of the engine. This gave them easy access to cool, dense air and, more importantly, gave the exhausts a clear shot out the tail of the bike. The expansion chambers required for two-stroke performance create significant packaging challenges, and this design meant the bike didn’t need to route them under or around the engine.

As expected, the TZR250 made bang-on the Japanese government-mandated 45hp limit, with plenty of extra available once de-restricted. With just 308lbs to haul around, including fluids, these are seriously nimble machines that require rider involvement and reward skill in a way that bigger bikes can’t hope to match.

These 3MA parallel-twins do have a bit of a reputation for being unreliable. But owners forums claim that’s mostly a myth, and that they’re just as reliable, or unreliable, as other two-stroke sportbikes of the period. As to why this particular design didn’t last, it’s not necessarily that the design didn’t work, it’s that the layout ultimately didn’t have enough of a benefit to continue development, and Yamaha switched to a v-twin in 1991 to keep pace with Honda and Suzuki.

Thank you for looking!!

Well hey man, if you think it’s running rich, maybe fitting those missing air cleaners might be a good idea? The seller also includes the usual start up and walk around video, which is always appreciated. Also, note the tach that doesn’t even bother with numbers below 3,000rpm…

Like so many of these little two-strokes that have shown up recently, this is no display piece, but appears to be in very nice physical condition. And while I’d worry about sourcing body panels and non-consumable parts, piston kits and the like are still available for these, so keeping them running shouldn’t be impossible with a bit of patience and effort. After making sure that the factory airbox and filter are present and accounted for, obviously…

If you happen to live somewhere a bike like this can be titled and ridden on the road, it would make a very fun addition to your stable and sure to start conversations every time you stop to top off! Which, considering the fairly dismal mileage these get, should be pretty often…

  • The coolest Yamaha made, in my narrow opinion! It isn’t running rich from the fitted airscreens, but the stock filtration would be the best choice for street use, however, this model had no reliable issues if the owner kept up on scheduled maintenance. These were the holy grail of the TZR model, even though dated suspension and low top hp #’s from restrictions kinda killed power, but there was one in S.F. that had some 59 ponies if I recall and ran stripe assed ape at Sears Pt. I would buy it!

  • Since the market is getting flooded with these bikes lately should we expect to pay less now for them. This is going out to the guy trying to sell this bitsa bike nsr250 locally for 12 grand.

  • lots of ridiculous prices at the end of the riding season for most people lately. it has to be priced within the value in reality if you actually want it to sell, this tzr is a good example of such

  • For sure would want to check this one out in person before plunking down cash.

  • since its already sold gl on the next one

  • If this has been ridden at speed over 10 miles w/o the airbox/filter I’m guessing its running rich because of sucking in debris through the forward facing carbs and wearing out the rings, pistons and cylinders. Those screens covering the open carbs only catch the big stuff. If the rings,pistons and cylinders were in good shape it should be way lean w/o the airbox/filter.

  • I agree with SR88…..the factory jetting is near perfect for a stock configuration and to modify it to by adding additional air it would run lean. I think this bike may have some problems….
