Frequently Asked Questions

How many performance clutch springs are included for the 1978-1981 CB400T and 1982 CB450T models?

One Japanese-made kit contains 4 performance clutch springs, enough to replace all 4 clutch springs on one compatible motorcycle.

What can performance clutch springs improve?

The firmer springs increase clutch clamping force and can help a serviceable clutch hold under higher load. They will not repair glazed friction plates, warped steel plates, incorrect adjustment or a notched clutch basket, and lever effort may increase.

Should the clutch springs be replaced as a complete set?

Yes. Install all 4 matched springs together, tighten the spring bolts evenly to the Honda service specification and reset clutch free play after assembly.
