Honda's first Super Sports 125 twin to use
the race CR93 type chassis, suspension and brakes.
125 super sports prior to this, the CB92 and
CS92 both had rather old fashioned, even for
that time leading link front forks, and a pressed
steel frame, and with a 'performance at all
costs' cam were not easy to keep on the boil,
a lot of fun never the less!
This CB93 addressed most of the problems,
it handled well, and looked great. The surprisingly
heavy weight (124kg/272lbs) sapped the performance
a little, which lead to the CB96, or CB160 as
most know it today.The weak point was the four
speed box, not because it was weak, but simply
needed a fifth cog to keep this peppy little
twin on the boil! At least the CB160 had a little
more torque, so was not as compromised as the
Of course the five speed box in later machines

The CB175 K4 gearbox will fit easily into this
engine, and improves the riding experience a
lot, and of course does not detract from the
original looks of the machine.
CB72 and CB77 owners would all attest to the
advantages of another ratio, so why not the
smallest twins, with even less mid range torque?
