Frequently Asked Questions

What size is the Honda front-wheel gearbox retainer O-ring?

One 54 x 2 mm O-ring is included. It seals the front-wheel speedometer gearbox or retainer assembly, and one is used at that location on the compatible motorcycle.

Which Honda OEM numbers cross-reference to the 54 x 2 mm retainer O-ring?

Current Honda OEM 91307-MB0-003 supersedes 91307-MB0-000 and 91302-317-700. Matching one of those numbers helps prevent confusing it with a similar-looking wheel O-ring of another cross-section.

Which Honda CB models use the 91307-MB0-003 front-wheel O-ring?

Fitment includes 1972 and 1974 CB350F, 1975-1977 CB400F, 1973 CB350G, 1974 CB360G, and 1975-1976 CB360T models.
