Model Information:

The Yamaha TZ 250 was a client racing motorbike with a water cooled, two-stroke, 250 cc engine produced by the Japanese manufacturer Yamaha.

In 1981 Yamaha was ready to introduce an all new TZ250. Known as the TZ250H, this design incorporated the powervalves (YPVS) found on the 500, providing more of a sensible balance between power and reliability. The new engine ran backwards from the previous design, helping even further in reliability. The single casting crankcase was replaced with left and right case halves and power was then tapped from the center of the engine. This design yielded a lower piston speed resulting in less bottom end problems. The powervalves employed a mechanical-governor design which kept them closed up to 8,750 rpm, opening fully by 11,000 rpm. This allowed a free flow of all exhaust gases.

The carburetor was updated with new Mikuni ZC units. The new TZ frame was 6.5 pounds lighter, with the engine positioned slightly forward of previous designs. A new rear shock and reduced rake angle added to the TZ’s improved ride. The spoke wheels were offered for the first time since the mid 1970’s.

This new TZ was expensive but well worth it for GP Racers. By the end of the 1981 season, the new machine proved to be very comparable the championship winning KR250 Kawasaki.

In 1984 was release of the TZ250L. This design moved the engine further even still, placing more weight on the front wheel. To prevent tank slapping, the swingarm and wheelbase was legnthened 40mm. Electrically driven powervalves and rejetted carbs improved performance considerably, putting out over 60HP. Again the cost of the new TZ went up.

1984 marked the last time a Yamaha 250 was to win the World Chamionship in the 1980’s.

Honda began releasing their all new RS250 in 1985 and the TZ’s I stop being competitive. The Honda with 70HP and it’s own twin-spar aluminum frame, the RS250 proved to be a far better design. Yamaha had seen this coming and in the TZ250N had attempted to match the call but was not possible.
