Increase performance throughout the power range with the FMF Big Bore Factory F Pipe. Designed for select KTM 85 SX and Husqvarna TC 85 two-stroke models, this performance expansion chamber supports strong, consistent power delivery for motocross and off-road riding. The Factory F Pipe design is built for riders seeking an effective upgrade over the original exhaust component.
Each FMF pipe is electro-nickel plated for a durable, non-chip finish that resists discoloration during normal use. Unlike the plated pipes, the Factory pipe features hand-pounded welds and no coating, matching the construction style used on works bikes. This detail provides an authentic factory-inspired appearance while maintaining the craftsmanship associated with FMF exhaust components.
Fitment includes the 2018-2021 KTM 85 SX in 17/14 and select 19/16 configurations, along with the 2018-2020 Husqvarna TC 85 in 17/14 and 19/16 configurations where specified. Verify the motorcycle model, wheel-size configuration, and exhaust requirements before installation. The manufacturer part number is FMF 025224, and the vendor part number is 78-1543F.
