Fast Bikes - - CORE TEST -

The mo­tor was made lighter and more com­pact, us­ing a sep­a­rate sleeve­less cylin­der block that aided re­builds in rac­ing. A new head con­fig­u­ra­tion added power while shed­ding weight, with shorter valve lengths. Ti­ta­nium in­take valves shaved off half a kilo to­wards a to­tal of 2.5kg lighter than the pre­vi­ous bike’s mo­tor. New forged pis­tons were 1mm wider, with a 1.5mm shorter stroke, mean­ing higher revs and a faster pickup. This led to the best midrange hit still not bet­tered even to­day! It also got a slip­per-clutch. Mass cen­tral­i­sa­tion was the key for this model. A (then) new four-piece cast alu­minium frame saved weight and in­creased rigid­ity. It’s 300mm slim­mer, fea­tured a new steer­ing head cast for the ram-air. The swingarm was 11mm longer. Sus­pen­sion re­mained as the pre­vi­ous bike, but fork span was down by 10mm and off­set was upped by 2.5mm for a faster re­sponse. Monoblock calipers were new for more power and less weight, along with lighter wheels. There is a ver­sion that comes with Honda’s C-ABS sys­tem, too.
