The mainstay of 250cc class racing at national and international level for many years, the twin-cylinder two-stroke Yamaha well deserved the title of 'privateer's friend'. Following its successful adoption for the 1972 works twins, water cooling first appeared on Yamaha's over-the-counter racers with the introduction of the TZ range in 1973. Power output remained the same as that of the preceding air-cooled TD/TR models, but reliability was much improved. Over the succeeding decade the TZ engine was updated with reed-valve induction, exhaust power valves, separate cylinders and a backwards-rotating crankshaft, but the layout always remained that of a parallel twin. On the chassis side, discs replaced the original drum brakes, a 'lowboy' frame was introduced, and an aluminium swinging arm adopted. From the mid-1980s onwards, a succession of more radical changes would see the TZ fundamentally altered.
The vendor advises us that this Yamaha TZ250F has been restored to concours condition and is correct in every detail apart from a non-original front brake master cylinder. The engine crankcases have been replaced, and although un-numbered are stamped with the correct 'DS7' prefix. Last run in July 2018, this beautifully restored TZ is described by the vendor as in excellent condition.
