About the Suzuki RM370

Three focused repair choices for the 1976–1977 RM370.

Suzuki Motorcycle Logo

The RM370 range covers fork oil seals, rear brake shoes and a plain steel clutch plate. Each product has an explicit 1976–1977 application, giving you a direct route from the repair to the part.

Keep replacement assemblies in the restoration record

A donor fork or rear wheel needs its own identification. Use the original seal dimensions or hub details alongside the RM370 model year; for clutch work, retain the plate pattern and thickness from the installed stack.

Restoring or customizing your RM370?

For an off-road build, choose grips and bars around the fitted controls, rider position and cable travel. Keep the original measurements if the goal is a period restoration.

Measure handlebar diameter, grip size, cable reach and clearance. Universal parts may require modification and are not a confirmed RM370 fit.

Suzuki RM370 parts questions

What parts are available for the RM370?
The current range contains a fork seal pair, rear brake shoes and an individual steel clutch plate, each listed for RM370 1976–1977.
Do the rear brake shoes also fit the front?
The featured listing establishes rear fitment only. Front shoes require a separate application for the installed front hub.
Does one steel plate replace the complete clutch?
No. It replaces one plain steel plate in the stack. Inspect the other steel plates, separate friction plates and related components before deciding the order quantity.
What if my RM370 has replacement forks?
Identify the donor fork and compare the removed seal’s inside diameter, outside diameter and full height/profile. The RM370 frame year alone cannot identify a seal for a changed front end.
