Model history
Production of the motorcycle started in 1973 with Model A (60 bhp @9,500rpm) and ended 1981 with Model H (72 bhp @ 11,000rpm) when the GP series came to an end. Production Racer were series manufactured racing bikes. Two Yamaha TZ 350 models are part of the motorcycle collection of the Technikmuseum Speyer.

Yamaha often leveraged the marketing of their RD and RZ series road motorcycles by referencing the TZ series. See also: RD250, RD350, RD400, RZ250, RZ350. The TZ motors provided the inspiration and engineering basis of Yamaha's contemporaneous road going two strokes.
