BETA FACTORY SILENCER BRONZE RR 4ST MY20>

Beta is proud to announce the new Factory Exhaust System for the MY20>> RR 4-Stroke models. Beta has developed one specific muffler and three variations of header pipe, all equipped with a 'power bomb' design to optimize the performance of each engine for MY20>>MY22 models


Each size of exhaust header is recommended for each engine displacement, but all header pipes can fit all of the 4-stroke engines, giving you multiple options to customize each engines power output and power delivery. No matter the combination, the exhaust system is FIM approved (112 Db limit) with specific EFI maps available from your local Beta Dealer.
