Product Details

This FMF Racing Powercore 4 Hex Muffler is built to give your Beta motorcycle a noticeable boost in horsepower and torque. It's designed to work across the entire power band, meaning the gains you feel are useful for all kinds of riding, whether you're on the trail or the track. This muffler fits a range of Beta models from 2010 to 2018, including bikes like the Beta 350 RR and the Beta 480 RR.

The construction here is a smart blend of performance and durability. The main body of the muffler is made from aluminum, which keeps the weight down while still being strong. For the parts that take more of a beating, like the end caps and internal components, FMF uses stainless steel. This combination means you get a well-built muffler that's ready for the demands of off-road riding. It also comes with a removable spark arrestor, which is a nice touch for trail use.
