Description
Piston d.50mm size B Metrakit 77cc Pro Race 4 Minarelli AM6, spare part for Metrakit 77cc cylinder.
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.
