Upgrade your mini motocross motorcycle with the FMF Factory Fatty Pipe, manufacturer part number 025101 and vendor part number 78-1507F. Designed to deliver an all-around power increase throughout the power range, this performance expansion chamber helps improve the engine’s power delivery for competitive riding and track use.
The FMF Factory Fatty Pipe features an electro-nickel-plated finish designed to resist chipping and discoloration. Unlike coated pipes, the Factory pipe uses hand-pounded welds and no coating, matching the functional appearance and construction style associated with FMF works bikes. This combination of performance-focused design and durable construction makes it a suitable replacement or upgrade for riders seeking dependable power gains from a 50cc motocross machine.
