VOCA Racing has successfully developed a homologated exhaust system for Minarelli AM6 and Derbi engines. Looking at the new VOCA Rookie 50/70cc (CE) exhaust systems one has to mention the outstanding finish, combined with the high quality VOCA aluminium silencer. The exhaust fits on 50cc original cylinders and assures excelent results on 70cc midrace cylinders (limitation of the exhaust has to be removed). The new VOCA Rookie 50/70cc (CE) exhaust is available for Minarelli AM6 and Derbi engines, with black or red silencer. Notice: The VOCA Rookie 50/70cc (CE) does not fit on Derbi GPR, Aprilia RS and Yamaha TZR models!
