Increase power across the usable RPM range of your two-stroke motocross bike with the FMF Fatty Pipe, manufacturer part number 023055 and vendor part number 78-1401. Designed specifically for the 2001–2007 Suzuki RM125, this performance expansion chamber improves throttle response and delivers a broad, all-around power increase for motocross and off-road riding.
Feature: Electro-nickel-plated finish provides a durable, non-chip surface that resists discoloration during normal use. The coating helps protect the pipe while maintaining a clean appearance. The factory-style pipe option features hand-pounded welds and no coating, replicating the construction used on works bikes.
Feature: Fatty power profile delivers balanced performance throughout the powerband, making it a versatile choice for riders seeking stronger acceleration and improved overall engine response. FMF also offers application-specific Gnarly and Factory Rev pipe designs for riders who prioritize low-end torque or middle-to-upper-RPM power.
The FMF Fatty Pipe is engineered for direct fitment on 2001, 2002, 2003, 2004, 2005, 2006, and 2007 Suzuki RM125 models. Verify the motorcycle year and configuration before installation.
