Unleash Your 85cc Potential with the Factory Fatty

The FMF Factory Fatty Pipe is the ultimate performance upgrade for young racers looking to dominate the track. Modeled after the legendary pipes used by factory race teams, the Factory Fatty provides a broader, smoother powerband that helps riders maintain momentum through corners and pull harder on straightaways.

Performance Features

  • Broader Powerband: Increases power across the entire RPM range for better versatility.
  • Factory Finish: Raw, unplated steel finish for that authentic factory race look.
  • Durable Construction: High-quality steel construction designed to withstand the rigors of racing.
  • Wide Fitment: Compatible with 2018-2024 KTM 85SX, Husqvarna TC85, and 2021-2024 Gas Gas MC85.

The Factory Fatty is engineered to improve throttle response and provide an immediate boost in mid-to-top end power. By optimizing the exhaust expansion chamber, FMF has created a pipe that allows your 85cc engine to breathe more efficiently, resulting in increased horsepower and torque. This is the same technology used by top amateur racers to reach the podium. Its raw finish gives your bike a professional, factory-tuned aesthetic that stands out in the pits. Installation is designed to be straightforward, fitting perfectly with your stock or aftermarket silencer. Elevate your racing experience with the proven performance of FMF.
