Exhaust Pro Circuit Platinum CR 125 2002

Pro Circuit Platinum

Although the Platinum exhaust does not have the factory look of the raw Works version, it still offers some advantages that should not be underestimated: maximum performance, minimum maintenance.

Performance Platinum exhaust

The Platinum exhaust from Pro Circuit improves the performance of any motorcycle across the entire RPM 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 power range as much as possible.

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

• Use of very stable 18-caliber steel
• Constructed from high-quality carbon steel with AKDQ stamp
• Welded and hammered by hand
• Reinforced mounting brackets and stinger
• Electroless nickel plating for 2 to 10 times longer service life
• Made in the USA

If you not only want performance, but also appreciate the look of factory motorcycles (because it's so much fun to scrub the bike after every ride) you should go for the Works exhaust from Pro Circuit.

For a great sound, we also have a good selection 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

As a general rule, please check if the exhausts fits BEFORE REMOVING THE RESTRICTOR, otherwise the exhaust cannot be returned.

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:

• Adjusting the carburetor by replacing the main jet.
• Upgrading the clutch or replacing the clutch springs.
• For scooters, it may be necessary to reduce the weight of the variator weights.

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.
