70cc or 77cc are simply not enough? We might just have what you need - Malossi 86cc Aluminium Cylinder Kit "MHR Team Big Bore", 44mm, Piaggio NRG / Runner (Piaggio / Gilera LC, 44mm stroke, 13mm pin).

Based on the "70cc MHR Team 2", this kit, with 50mm bore and 44mm stroke, has no less than 86cc in stock. It is basically identical to the 77cc kit, except that the stroke is longer (44mm), that it can only be run with 85mm connecting rod and that it has a 13mm piston pin.Port timings are slightly shorter to increase torque. The Malossi 86cc Aluminium Cylinder Kit "MHR Team Big Bore", 44mm, Piaggio NRG / Runner can reach 22/24hp out of the box (without modifications to cylinder).

As with all "MHR Team" cylinders, you'll have to mill the crankcase to make room for the cylinder base and the crankshaft.

Note: this kit can only be run with crankshafts with 44mm stroke, 85mm connecting rod and 17mm needle cage (for 13mm piston pin.)

For Piaggio / Gilera LC engines
Diameter - 50mm / Stroke 44mm / Connecting Rod - 85mm

Notes and Safety

How to Install a cylinder on a scooter, motorcycle or moped

The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.

The service life of a cylinder depends on whether it has been fitted correctly.

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.
