Malossi have been hard at work producing a new race specification rotary valve crankshaft for the Vespa PX125/150 range of scooters which is available from VE (UK)
The new innovative design features a unique shape optimised for gas flow by incorporating the suction phase of the 2T cycle in to the crank half. The crank halves have been perfectly balanced through the use of tungsten inserts for counterweights.
The crank has a standard length stroke of 57mm making it suitable for both road and track use on engines using cylinder capacities up to 178cc.
