Increase performance across the powerband with the FMF Fatty Expansion Pipe, manufacturer part number 020015. Designed for the 1990–1997 Honda CR125R, this performance exhaust pipe delivers an all-around power increase while maintaining the responsive two-stroke characteristics expected from a dedicated motocross pipe. The Fatty configuration is suited to riders who want stronger, more usable power throughout the engine’s operating range.
Feature: The pipe is electro-nickel plated for a durable, non-chip finish that resists discoloration during normal use. The factory-style pipe option is finished differently, with hand-pounded welds and no coating, replicating the appearance and construction style of FMF works bikes.
Built for off-road and motocross applications, the FMF Fatty pipe is engineered to complement the Honda CR125R engine and fit the listed model years. It is a direct-fit performance upgrade for riders seeking improved acceleration, stronger pull between shifts, and broader power delivery without changing the motorcycle’s basic exhaust system design. Always verify the motorcycle model, year, and existing exhaust components before installation.
