1990 Yamaha TZ250A
Miles: n/a
Listed Price: $21,000
Apologies for posting yet another Yamaha this week, but I promise: this is the last one. First sold in 1986, Yamaha’s TZR250 was the company’s entry into the hotly contested 250cc two-stroke sportbike category. Powered by a parallel-twin suspended from Yamaha’s iconic “Deltabox” frame, it was light and quick, and proved to be a very popular machine. This 1990 Yamaha TZ250A, however, was a factory racing machine: never intended for road use, it was the purest incarnation of Yamaha’s liquid-cooled, parallel-twin sportbike. As can be seen from the photos, the design featured a “reverse cylinder” layout, with the intake and carburetors at the front of the engine, and the exhaust exiting directly under the tank and out through the tail section, a feature that was also found on the 1989-1990 3MA version of the roadgoing TZR250. By 1990, the TZ250 was producing approximately 78hp and weighed in at 216lbs dry, but the writing was on the wall and, in 1991, the parallel-twin was replaced with a v-twin that offered a narrower cross-section and produced less vibration.

Imported into New Zealand from the Yamaha factory in 1990 and successfully campaigned in National events.
The best and last of the parallel twin two stroke race bikes.

I’m always amazed by how simple two-stroke Grand Prix machines like this Yamaha TZ250A are, with the fairings removed: there’s just no there, there. What can be seen is obviously very trick, with a visible dry clutch and the aforementioned reversed-cylinder layout. This bike is currently located in New Zealand, but the seller is obviously motivated to sell, as I actually found it listed on the Los Angeles Craigslist page. And yes, the price is listed in US dollars. There isn’t any significant provenance listed, but it is claimed to be a factory Yamaha machine and comes with a bunch of parts and spares, something that could save a ton of headaches if you plan to make use of this bike on track.

Nothing to be sorry about!
