The FMF Fatty Pipe is designed to deliver an all-around power increase across the engine’s usable power range. Part number 025119 is engineered for select KTM and Husqvarna two-stroke motorcycles, making it a practical performance upgrade for riders seeking stronger, more versatile power delivery on the track or trail.
Built by FMF Manufacturing, this Fatty expansion chamber uses an electro-nickel-plated finish for durable, non-chip protection that resists discoloration during normal riding conditions. The plating provides a clean appearance while helping protect the pipe from the demands of off-road use. Its power characteristics are suited to riders who want balanced performance rather than a pipe focused exclusively on low-end torque or high-rpm output.
Fitment: The FMF Fatty Pipe fits 2011–2015 KTM 150 XC models, 2012 KTM 125 SX, and 2014–2015 Husqvarna TC 125 and TE 125 models. Confirm motorcycle year, model, and exhaust configuration before installation to ensure proper fitment. Manufacturer part number 025119 and vendor part number 025119 identify this FMF replacement and performance exhaust component.
