Notes and Safety

PRO CIRCUIT Works

The Works exhaust is one of the most popular 2-stroke motocross exhausts. With its "factory" look and high performance, it has won a firm place in the hearts of riders.

Pro Circuit Works performance

The Works exhaust from Pro Circuit improves the performance of any motorcycle across the entire rev range. Pro Circuit generally tries to improve and compensate for the weak points of each motorcycle without completely distorting the original character of the engine. The aim is to increase the usable rpm range as much as possible.

This exhaust is suitable for both motocross and supercross. The Platimum 2 is more suitable for enduro.

  • Constructed from high-quality carbon steel with AKDQ stamp
  • Welded and hammered by hand
  • Reinforced mounting brackets and stingers
  • Untreated finish
  • Made in the USA

If you want the same performance but don't want the high-maintenance factory finish, you can use the nickel-plated Platinum instead.

For top sound, we also offer a wide range of Pro Circuit silencers, from the R-304 for Supercross to the ultra-quiet Type 296 for Enduro

Exhaust scooter, moped, motorcycle

The exhaust has a major influence on the performance of scooters and mopeds. By replacing the original with a tuning exhaust, you can improve the gas flow and increase the engine power.

exhaust parts

  • The headpipe or header is the connection between cylinder and exhaust, and an exhaust gasket provides the necessary seal. In street-legal systems, the headpipe is equipped with a legally required restriction. Some people remove this restrictor to increase power.
  • The actual exhaust body or expansion chamber is connected to the header pipe. In a classic 2-stroke expansion chamber type exhaust, gas pressure waves are used to improve engine performance.
  • At the end there us the silencer or muffler that discharges the exhaust gases and, with the help of damping wool, also reduces the noise generated by the vehicle.

Replacing the exhaust

For 2-stroke engines, various settings and components usually need to be adjusted when the original exhaust is replaced with a tuning version. These changes include:

Tuning Level: Racing

We categorize our products into different performance levels  Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.

Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
