Upgrade the power delivery of your 2005–2007 Honda CR125R with the FMF Fatty Expansion Pipe, manufacturer part number 021048 and vendor part number 78-1128. Designed for an all-around power increase, this performance exhaust pipe helps improve power throughout the engine’s usable range while maintaining the responsive characteristics expected from a high-performance two-stroke system.
The FMF Fatty pipe is electro-nickel plated for a durable, non-chip finish that resists discoloration during normal use. This model is engineered for riders seeking balanced performance across the powerband, making it a practical choice for motocross, trail, and general off-road riding. FMF also offers Gnarly pipes for increased low-end torque and Factory Rev pipes for stronger middle- and upper-rpm performance, but the Fatty is the versatile option for broad power gains.
Designed specifically for the Honda CR125R, this pipe supports direct fitment on 2005, 2006, and 2007 model-year motorcycles. Its formed expansion-chamber design works with the CR125R two-stroke engine to optimize exhaust flow and throttle response. Verify motorcycle year and configuration before installation, and follow the manufacturer’s recommended installation procedures for proper fit and performance.
