Model history[edit]

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.
