1983 Honda CB450SC Nighthawk Suspension Mounts & Wheel Service Choices

For the 1983 CB450SC Nighthawk, separate maintenance of the original fork and wheels from selection of universal shorty shocks. The seal and bearing listings give clear sizes or counts. A custom shock order needs the fitted mounts and clearance checked before its 290 mm length or finish becomes the deciding factor.

1983 Honda CB450SC Nighthawk · Suspension & Wheel Buying guide

Settle custom mounts before combining service parts

The chrome shorty shocks use an upper eye and lower clevis. Fork seals measure 33 × 46 × 11 mm, while front 6302-2RS bearings are individually supplied with two specified per front wheel.

Use the mounting arrangement as the first shock decision

The shorty listings distinguish eye-to-clevis and eye-to-eye products. They are universal custom shocks, so matching the motorcycle name cannot settle the lower mount. Compare the fitted joints, bushing sizes, mounting widths and clearance before choosing a finish or planning a height change.

Build wheel and fork quantities from separate listings

The front bearing is sold individually, with two required at the front wheel. The fork package includes two oil seals, and the rear-wheel seal includes one piece. Those units belong to different assembly locations and should be entered separately when combining maintenance orders.

Common questions

What must be confirmed before choosing the chrome 290 mm shock pair?

Confirm a compatible upper eye and lower clevis arrangement, including mount size and width. The source also requires checks of travel, tire-to-fender, chain, exhaust and stand clearance. Its short custom length does not promise original-height fit on this motorcycle.

Does the two-seal bearing description mean two front bearings arrive?

The 6302-2RS bearing’s two synthetic seals describe one bearing. Each bearing is sold individually, with two required per compatible front wheel. Use an order quantity of two if both front bearing positions are being renewed.

Which separate seal sizes should I record for fork and rear-wheel work?

Record 33 × 46 × 11 mm for the two-piece fork oil-seal package. The rear-wheel seal is separately supplied as one 28 × 47.2 × 7 mm piece. Match each dimension to its own fitted assembly, particularly when forks or wheels have been changed.
