The FMF Fatty Pipe is designed for the 2025 Beta 300 RX two-stroke motorcycle, delivering an all-around power increase throughout the power range. This performance exhaust pipe is engineered for riders who want strong, usable power across the engine's operating band, making it well suited to motocross, off-road riding, and varied terrain. Manufacturer part number 025318 and vendor part number 025318 identify this FMF Fatty model.
Feature: Electro-nickel plating provides a durable, non-chip finish designed to resist discoloration during normal use. The plated construction offers a clean appearance and dependable performance, while the factory pipe option remains uncoated and features hand-pounded welds modeled after works bike construction.
Feature: Fatty configuration provides balanced power gains throughout the powerband. FMF also offers Gnarly and Factory Rev pipe designs for different riding preferences, including increased low-end torque or stronger middle- and upper-rpm performance. The Gnarly option uses heavy-duty 18-gauge steel for increased durability in demanding off-road conditions, while the Factory Rev option is suited to riders seeking more top-end power, longer time between shifts, or improved performance in deep berms and sand.
