Description

Piston Malossi MHR Alu 50cc D.40mm 12mm MBK Nitro / Piaggio NRG.

Malossi, manufacturer of high quality tuning parts for scooters, mopeds & Co, is an integral part of the 50cc scooter scene and racing. Constant innovations and consistent first-class quality have made Malossi a must-have for tuning fans.

The piston with piston ring(s), piston pin and locking clips is the moving heart of the cylinder. Due to the constant up and down movement, the piston is subject to wear. At some point, the tolerances are no longer correct, the piston ring no longer seals perfectly and the performance decreases, i.e. the piston must be replaced.

Notes and Safety

Malossi MHR

The MHR series from Malossi is generally available in 3 categories for the most popular models:

The 3 model series differ in terms of performance and competitiveness. The MHR Team series includes the top-of-the-line  models with outstanding performance for racing. The MHR Racing is in the middle, and the MHR Replica adopts the basic features of the higher versions, with the emphasis on reliability for everyday use rather than maximum performance for the race track.

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: High End 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.

High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.

Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.

    Aluminium cylinders

    Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.

    How to run in an aluminium cylinder?

    Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.

    Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
