About FMF Racing
Performance exhaust systems for motocross, off-road, and ATV — the industry standard
FMF Racing has been making performance motorcycle exhaust systems since the 1970s and is one of the most-used names in motocross and off-road performance. The FMF lineup covers slip-on mufflers, full exhaust systems, and spark arrestors across virtually every motocross, dual-sport, ATV, and UTV application. The Powerbomb header and PowerCore/Q4 muffler combinations are FMF's signature products.
Chaparral Motorsports has been an authorized motorcycle and powersports dealer since 1980. We stock FMF Racing alongside the full range of motorcycle, ATV, and UTV gear, and our parts counter can confirm fitment and compatibility before you order.
