The Yamaha TZ 350 was a racing motorcycle produced by the Yamaha Motor Company from 1973 to 1981 for competition in the Grand Prix motorcycle racing series. The motorcycle was powered by a 350 cc two stroke engine.
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.[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 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.
