Honda CBR 250RR MC22
mc22 l 1990-1991
CBR 250RR MC22 is a completely redesigned from the previous model bike that had a new cast/pressed aluminum
frame that gave a more aggressive riding position, gull shaped swing-arm that was adopterd from the NSR250R,
highter rising tail, six spoke cast aluminium wheels and dual front 276mm floating disc brakes. These changes
resulted in a dry weight of 142kg. The olny feature that was adopted from the previous model was the MC14E
engine. This was slightly modified with a crankshaft that had 27.5mm small-end journals, up 0.5mm from the
previous 27mm journals. The engine also used a completely new set of VP carburetors that had smaller throats,
reduced from 32mm to 30.5mm. These carburetors were fed by a vacuum operated pump for fuel delivery.

mc22 n 1992-1993
Essentially the same as the (L) models, except the new paint job.
mc22 r 1994-1996
Still very similar to the (L/N) models, but restricted to producing 40ps due to changes in
Japanese law. The restrictions were in the cylinder head, head gasket and ignition unit.
Redline reduced to 18.500rpm (from 19.000rpm).
