Product Details

The FMF Fatty Pipe is the most copied expansion chamber design in motocross, trusted by riders worldwide for its proven performance gains. This exhaust pipe is engineered specifically for the KTM 125SX (2000-2003) to deliver a broader, smoother powerband across the RPM range, making power more accessible and controllable.

Key Features:

  • Broader, smoother powerband for improved rideability and acceleration
  • Legendary FMF Fatty design that has set the standard for two-stroke performance
  • Durable nickel-plated finish resists corrosion and maintains appearance
  • Includes replacement O-rings for proper installation and sealing
  • 100% manufactured in the USA with FMF's quality craftsmanship

The Fatty Pipe utilizes FMF's decades of racing experience and dyno testing to extract maximum performance from your two-stroke engine. The carefully engineered expansion chamber design optimizes exhaust wave dynamics to improve power delivery throughout the powerband, not just at peak RPM. This makes the bike easier to ride while still delivering the performance you need on the track or trail.
