These are interesting as the side cam drive
type engine is a lot lighter then the center
cam chain type, the bore and stroke also favours
higher revs and more performance. The weakness
if this machine, rather like the CB92 before
it, was the four speed box compromised it's
performance, and the lack of a rev counter was
also a problem.
These problems were addressed with the very
much rarer Honda CB125K2.
