1981 Honda CB900F Supersport · Clutch Lock Nut Buying guide
The nut is identified as Honda 90231-KCS-651 with several superseded references. Match the parts diagram and actual assembly before ordering, especially if the engine or clutch has been changed.
The product spans several models and mentions clutch-basket and oil-filter-rotor applications. Those uses are not automatically both present on the CB900F. Check the appropriate parts diagram or service information before choosing the nut, keeping its reference tied to the assembly actually being serviced.
A replacement nut cannot restore a damaged shaft thread or an incorrect assembly stack. Confirm the exact location in the parts information, inspect the mating components and use the Honda service procedure for holding, tightening and locking. The broad clutch-and-filter-rotor product description spans other Honda designs.
No. The original F has a paper-element oil filter in a center-bolt housing. Confirm this nut’s required location and reference in the fitted clutch assembly; do not transfer centrifugal-filter-rotor uses from other motorcycles to this one.
No. Inspect the shaft threads, nut engagement and associated locking parts before assembly. A damaged thread or incorrect stack of parts needs correction first. Follow the Honda holding and tightening procedure instead of using extra force to make the nut secure.
Identify the actual assembly and check its parts information for the required nut and locking method. The original CB900F year and the general 16mm description cannot verify hardware in a different clutch or engine.
