Stainless steel, aluminum end piece, expansion chamber clear varnished "Economy + Fashion" for 50 cc scooters. Complete with bracket, gasket and, if necessary, variator rollers and clutch springs for optimal tuning. All systems are supplied with reduced power, i.e. with a throttle restrictor in the front manifold. For sporting purposes, this restrictor can be easily removed by means of a small spot weld.
