What to Expect

Longer stroke CB450K engine became fragile – pitted cams, worn valve guides, broken piston rings and blowing head gaskets. However, those left on the road have fixed the problems (often by using CB450 bits) and with upgraded suspension and brakes can make useful hacks until about 50k when the engine is seriously worn out! The electrics and wheel castings are also suspect at this age.
