Stainless steel, aluminium end cap, expansion chamber with clear lacquer finish "Economy + Fashion" for 50 cc scooters. Supplied 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. Power increase by derestriction approximately 20%. All models with TÜV E-approval (E-Pass) are already StVZO-approved (a TÜV registration is not required). Of course, the E-approval becomes invalid if the throttle is removed. Approval E-approval Main colour grey Type scooter Type/kind Article Variation complete installation
