1983 Honda CB450SC Nighthawk · Sprockets Buying guide

Check gearing, wear and retention as one order

A 17-tooth front sprocket is a specific choice rather than proof of the motorcycle’s present gearing. Compare chain pitch, spline profile, offset and retaining method with the fitted parts. Then inspect the chain, rear sprocket and locking plate to decide which components need renewal.

Parts to consider

Let drive-set condition determine the replacement scope

Inspect for hooked sprocket teeth, tight chain links and excessive chain stretch. The sprocket information advises replacing worn drive components together, because an old chain or rear sprocket can quickly wear the new front sprocket. Finish slack and alignment checks to Honda specifications.

Renew a damaged locking plate

A bent or cracked plate, worn bolt holes or insecure locking are reasons for replacement. After assembly, verify sprocket orientation, chain alignment, bolt tightening and locking against the Honda procedure. The supplied two-bolt count does not substitute for those checks.

Sprockets ordering questions

What change should I expect if my current front sprocket has fewer than 17 teeth?

A larger 17-tooth front sprocket generally lowers engine rpm at a given road speed and reduces mechanical leverage. The actual change depends on both fitted tooth counts, so compare the current front and rear gearing before choosing this replacement.

Which wear findings should expand a front-sprocket order?

Look for hooked teeth, tight links and excessive chain stretch across the chain and rear sprocket. Worn drive components should be replaced together; renewing only the front sprocket can leave it working with parts that quickly accelerate its wear.

When should I include a replacement lock-plate set?

Include it if the old plate is bent, cracked, worn at its bolt holes or no longer locks securely. The set supplies one 23811-292-000 plate and two 92101-06016-0A bolts, enough to renew the listed retention hardware at one front sprocket.
