The Yamaha TZ 350 is a 2 stroke 350 cc Production Racer sports motorcycle. Production of the bike 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.[1]

Production Racer were series manufactured racing bikes. Two Yamaha TZ 350 models are part of the motorcycle collection of the Technikmuseum Speyer.[2]

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