The FMF Factory Fatty Pipe is designed to provide an all-around power increase throughout the engine’s power range for select KTM and Husqvarna 85cc motocross motorcycles. This performance exhaust pipe uses FMF’s Factory Fatty design to help enhance throttle response, broaden usable power, and deliver strong performance across the track. Manufacturer part number 025154 and vendor part number 78-1537F identify this FMF replacement and performance component.
The pipe is electro-nickel plated for a durable, non-chip finish that resists discoloration during normal use. This coating helps protect the pipe while maintaining a clean appearance through repeated riding and exposure to track conditions. As with FMF’s Factory pipe construction, the exhaust features hand-pounded welds and no coating, matching the appearance and construction style associated with works bikes. The included design is intended for riders seeking improved engine performance without sacrificing broad, usable power.
Fitment includes 2014 through 2017 Husqvarna TC 85 models with 17/14 wheels and 2006 through 2011 KTM 85 SX models with 17/14 wheels. Verify the motorcycle year, model, wheel configuration, and exhaust interface before installation. The FMF Factory Fatty Pipe is built specifically for compatible 85cc two-stroke applications and is intended to replace the original exhaust pipe with a performance-focused FMF system.
