Modified RC-ONE crank case from Malossi for scooters equipped with Piaggio water-cooled engines. The crankcase is designed specifically for the installation of the 94ccm flange mount cylinder (M. 3115883) and the corresponding 44 mm MHR team RHQ crankshaft (M. 5316029) has been developed and can be used only in combination with these parts. In conjunction with the correct exhaust pipe (M. 3216158), carburettor(M. 1616276) and the appropriate ignition (M. 5515001) performance values are expected above the 30hp mark. The shock absorber is positioned so that the crankcase for scooters with short wheelbase (10 inch) can be used as well as scooters with a long wheelbase (12 or 13 inches). There are also allowances for disc and drum brake. Delivered including all parts shown: reed block, intake manifold, oil seals, bearings etc.
