About the Yamaha TDR250
Service a distinctive two-stroke TDR with clear separation between engine, fork and brake applications.
Introduced in 1988, Yamaha’s TDR250 uses a liquid-cooled two-stroke twin derived from the TZR250. That engine background is useful when researching the bike, while replacement parts still need a confirmed TDR250 application. Keep engine identification separate from the fork and brake details on an imported or modified example.
Choosing TDR250 service parts
Build an engine gasket order around the joints being opened and the set’s actual contents. For front brake work, identify the handlebar master cylinder and compare its repair parts. The fork seals use a different year range from the two kits, making separate component records especially useful for this model.

1988 engine and brake applications
The featured engine gasket set and front master cylinder repair kit list 1988. Verify the kit contents and the relevant engine or cylinder assembly.
1989–1990 fork application
The featured fork seals list 1989–1990 and 38 × 50 × 10.5 mm dimensions. That coverage does not add those years to the 1988 gasket or brake kit.
