Show original supplier description
The FMF Factory Fatty 023043 exhaust pipe is designed to emulate the performance characteristics of "works" or cone pipes used by factory racing teams. It offers a significant improvement by broadening and smoothing out the power curve, delivering more low-end torque, enhanced mid-range power, and increased over-rev capabilities. This pipe is suitable for various riding styles, providing benefits across the entire power band. Constructed with meticulous craftsmanship, the Factory Fatty features a body made from lighter 20-gauge steel and a header portion from robust 19-gauge steel. The seams are hand-pounded to ensure smooth transitions and optimal exhaust flow. Most models include O-rings for a secure fit. This FMF Factory Fatty pipe is specifically designed for the Suzuki RM85, fitting model years 2002-2025, and the RM85L for model years 2003-2012. It is important to note that fitment information is based on the stock version of the motorcycle; any added accessories or modifications could potentially affect fitment accuracy.
