The FMF brand specializes in off-road exhausts, drawing on its experience in Motocross, Enduro and Supermotard competition.

From the outset, Factory 4.1 RCTs stand out from other mufflers thanks to the use of top-of-the-range materials, providing increased power and torque across the entire engine speed range, as well as considerable weight savings compared to the original system.
