FMF Factory 4.1 RCT Slip-On Muffler #041595 for Honda CRF125F 2019-2021

Product Details

FMF's Factory 4.1 RCT SL slip-on muffler incorporates the latest in RCT (Resonance Chamber Technology) both internally and externally. The core's shape lowers decibels without compromising power output. In addition, FMF designed the muffler specifically to achieve a shorter overall length so as to be less susceptible to crash damage. Complementary to FMF's Factory Forward Engineering, the muffler is also moved closer to the motor to centralize mass and improve handling. Each FMF Factory 4.1 RCT slip-on muffler is constructed from only aerospace grade materials that meet the California company's exacting specifications.
