Factory Fatty Exhaust Pipe 09-15 KTM SX 65 - FMF 025103

The Factory Fatty 025103 delivers outstanding performance by emulating the acclaimed “works” or cone pipe design once favoured by factory teams. Constructed with high-quality materials and hand-crafted seams, it broadens and smooths the power curve across the entire rev range. Riders experience enhanced low-end torque, stronger midrange, and increased over-rev, making the Factory Fatty a top choice for any off-road discipline. Lighter steel construction reduces weight while maintaining durability, with included O-rings ensuring a precise, reliable fit.
