CB400 Super Four

< Home

The CB400 super four was never officially sold in north america. Maintenance items can be hard to come by from domestic sources, however honda being honda they’ve shared many parts with other honda sport bikes, and a number of parts are shared with the CB-1 which was sold in the united states and canada in 1989 and 1990.

All items on the list are for the 2002-2003 CB400SF (CB400SF2) unless otherwise noted. Parts diagrams can be used as a reference for other years.
