New 2024 KTM 50SX Exhaust

 

CORONA, CA - August 10, 2024 - The highly popular 2024 KTM 50 SX machine now has two new Pro Circuit products that can easily upgrade the bike's look and performance. Once a Pro Circuit Works Pipe is installed, riders quickly notice an increase in horsepower and torque gains across the entire RPM range. The unplated, oiled metal finish requires some maintenance but really gives your bike that "Works Look."

 

The R-304 Silencer was developed as a full-race two stroke silencer. The compact design of the short aluminum canister offers optimum performance gains and is recommended for closed-course racing only. Hex-head screws are used to secure the inlet cap and can be removed easily for quick re-packing of the silencer. With the addition of these two products, young racers will be ready for the next gate drop!
