Choosing parts for your Yamaha TT500
Confirm TT500 rather than XT500: Yamaha describes these as distinct models, and part applications vary. A shared engine family or product title does not make every item interchangeable.
Keep the year with the repair: the gasket set covers 1977–1981, intake holder set 1977–1978, float needle and seat 1978, and oil-seal kit 1980–1981. Check the specific part and fitted assembly before ordering.
Yamaha's history of the TT500 and XT500 describes the TT500 as its enduro model developed for the U.S. market. Send PartsNMore your model year and photos of the original part if you need help identifying it.
