Upgrade the exhaust performance of your compatible Beta motorcycle with the FMF Factory Fatty Pipe, manufacturer part number 025271 and vendor part number 025271. Designed for the Beta 250 RR and Beta 300 RR two-stroke models, this performance expansion chamber is engineered to deliver an all-around power increase throughout the engine’s operating range. Its Factory Fatty profile provides a balanced combination of low-end response, mid-range pull, and top-end performance for demanding off-road riding.
Each FMF pipe is electro-nickel plated for a durable, non-chip finish that resists discoloration during normal use. This pipe is built to withstand the harsh conditions associated with trail and competition riding while maintaining a clean, professional appearance. The electro-nickel plating distinguishes it from the Factory pipe, which features hand-pounded welds and an uncoated finish modeled after works bikes.
