1983 Honda CB550SC · Suspension & Wheels Buying guide

Separate sealing work from bearing and mounting hardware

The oil seal dimensions are stated, the dust-seal package explicitly contains two, and the front-bearing listing gives a usage count. Steering hardware and shock fasteners should be considered independently of those sealing and bearing purchases.

Keep the two fork-seal orders distinct

The oil-seal set gives 37 × 50 × 11 mm dimensions, while the dust-seal listing explicitly states two per pack. Both include the 1983 CB550SC, but they are separate products. Check which sealing components need replacement rather than assuming either purchase is a combined oil-and-dust-seal package.

Identify bearing location as well as its name

The 6302-2RS bearing is listed for the front wheel. The tapered steering conversion instead names upper and lower races, with its own CB550SC application. Match the bearing location being serviced, then assess stem hardware separately instead of treating a general front-end repair as one interchangeable bearing purchase.

Choosing parts for your CB550SC

Does the dust-seal package contain the oil seals?

The dust-seal description states two dust seals per pack. The oil seals have their own 37 × 50 × 11 mm listing. Neither description establishes a combined package, so select each according to the sealing work required.

Do the shock listings establish the stock CB550SC length?

The shorty products describe universal custom applications with 290 mm measurements and different mount arrangements. They do not give a CB550SC-specific original length, so compare the fitted suspension before selecting a custom shock.

Are the front-wheel and steering bearings the same purchase?

The front-wheel item is identified as 6302-2RS, while the steering listing describes a tapered conversion with upper and lower races. Their separate locations and contents should remain attached to the repair when choosing either product.
