Increase overall engine performance with the FMF Fatty expansion chamber pipe, manufacturer part number 021040. Designed for the 2003 and 2004 Honda CR250R, this pipe is engineered to deliver a broader power increase throughout the power range. It is a practical performance upgrade for motocross and off-road riders seeking stronger, more usable power without changing the motorcycle’s intended riding characteristics.
Feature: The FMF Fatty pipe uses electro-nickel plating for a durable, non-chip finish that resists discoloration during normal use. The factory pipe is the exception, featuring hand-pounded welds and no coating for a traditional works-bike appearance.
Feature: FMF offers multiple pipe designs for different riding needs, including Fatty for all-around power, Gnarly for increased low-end torque, and Factory Rev for stronger middle- and upper-RPM performance. The Fatty configuration is suited to riders who want balanced performance across the CR250R powerband.
Built for direct fitment on 2003 and 2004 Honda CR250R models, the FMF 021040 pipe supports responsive acceleration and consistent power delivery. Verify the motorcycle model and year before installation, and use the appropriate mounting hardware and exhaust components for a proper fit.
