Minstay of 250cc and 350cc 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 on the 1972 works twins, water cooling first appeared on Yamaha's over-the-counter racers with the introduction of the TZ 'A' range in 1973. Power output increased only marginally over 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. With Yamaha concentrating their resources on developing their 500 Grand Prix bike and the new TZ750, the smaller TZs remained unchanged through 1974 (TZ250/350B) and 1975 (TZ250/350C). Mono-shock rear suspension and disc brakes came in with the 'C' models for 1976 together with revised cylinder porting and reshaped expansion chambers. Few changes were made to the successor 'D' and 'E' models.

This matching-numbers TZ350E has been upgraded with a TZ750-style twin front disc brake. Its history, condition and completeness (or otherwise) are not known and thus the machine is sold strictly as viewed.
