The FMF Factory Fatty Expansion Chamber Pipe is designed to deliver an all-around power increase throughout the usable power range of compatible Suzuki RM85 motorcycles. This performance pipe helps improve engine response and power delivery for riders seeking stronger, more consistent performance across a broad range of riding conditions. The Factory Fatty design is engineered specifically for motocross and off-road applications and is built to complement the characteristics of the RM85 engine.
This FMF pipe features a durable electro-nickel-plated finish designed to resist chipping and maintain its appearance without discoloring under normal use. Unlike the plated sections, the Factory pipe includes hand-pounded welds and no coating, replicating the appearance and construction style of FMF works bikes. The result is a performance-focused exhaust component with a purposeful, race-inspired finish.
The FMF Factory Fatty Pipe, manufacturer part number 023043 and vendor part number 78-1427F, fits select Suzuki RM85 models from 2002 through 2009, as well as the 2012 and 2015 model years. Verify the motorcycle year and existing exhaust configuration before installation to ensure proper fitment. Professional installation is recommended for correct alignment, secure mounting, and reliable sealing at all connection points.
