Metrakit Pro Race
The Pro Race series from Metrakit consists of extremely powerful high-end parts for 50cc scooters and motorcycles, e.g. cylinders, crankshafts and exhaust systems.
The motto of this series is pretty straightforward: maximum performance. The Pro Race products offer very high maximum power with an emphasis on the upper RPM range, making them ideal for use on the race track.
To make full use of the power, we recommend using a carburetor with a large diameter, a large-volume intake system and a reinforced clutch.
When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
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.
