DESCRIPTION

A completely redesigned bike from the previous generations that had a new cast/pressed aluminum frame that gave a more aggressive riding position, gull shaped swing arm that was adopted from the NSR250R, higher rising tail, six spoke cast aluminum wheels and dual front 276 mm (10.9 in) floating disk brakes. These changes resulted in a dry weight of 142 kg (310 lb). The only feature that was adopted from the previous model CBR250s was the MC14E engine. This was slightly modified with a crankshaft that had 27.5 mm small-end journals, up 0.5 mm from the previous 27 mm journals. The engine also used a completely new set of VP carburetors that had smaller throats, reduced from 32 mm to 30.5 mm. These carburetors were fed by a vacuum operated pump for fuel delivery.
