FMF Fatty Expansion Pipe 020054 for 1997–2000 Kawasaki KX250

Upgrade the power delivery of your two-stroke motorcycle with the FMF Fatty Expansion Pipe, manufacturer part number 020054. Designed for an all-around power increase throughout the power range, this pipe helps provide balanced performance for trail riding, motocross, and varied off-road conditions. The Fatty profile is intended for riders who want improved overall response without focusing exclusively on low-end torque or top-end output.

The FMF 020054 pipe fits 1997, 1998, 1999, and 2000 Kawasaki KX250 models. Its electro-nickel-plated finish provides a durable, non-chip surface that resists discoloration under normal riding conditions. The coating is not applied to the factory pipe option, which retains hand-pounded welds for an authentic works-style appearance. This product is built to complement the KX250 engine and support strong, usable performance across the powerband.

FMF offers several pipe profiles for different riding priorities. Fatty pipes are designed for broad, all-around power, while Gnarly pipes emphasize low-end torque and Factory Rev pipes concentrate power in the middle and upper RPM range. The FMF Fatty expansion pipe is the appropriate choice for riders seeking a versatile performance upgrade for general riding and mixed terrain. Confirm the motorcycle model and year before installation, and use the included or required mounting hardware according to the manufacturer’s instructions.
