About the Yamaha IT425
A focused 1980 IT425 service selection for clutch wear, drum brakes and fork sealing.
A vintage Yamaha IT425 restoration needs a record of the engine, fork and brake assemblies actually installed. Keep its model name distinct from the neighboring IT400 and IT465 when researching the IT enduro family. That distinction is particularly useful on a bike rebuilt with mixed period components.
Choosing IT425 service parts
The three repair examples list 1980: an individual clutch plate, drum brake shoes and fork oil seals. Check the plate’s position in the clutch stack, compare the shoe profile with the intended wheel, and use the removed seals to confirm the fork dimensions. These details turn the model-year match into a practical parts order.

IT425 within the IT family
Use the 425 designation throughout your search. A part shared with IT400 or IT465 must still list the required IT425 application and match the installed component.
Drum brake shoe matching
Check the shoe profile, operating ends and brake assembly. A 1980 model match alone does not establish wheel position or confirm parts for a substituted wheel.
