Malossi 290cc Cylinder Kit, d = 74mm, Yamaha X-Max / Majesty 250cc to ramp up your 4-stroke maxiscooter, available at a very good price!

The kit includes an aluminium cylinder with piston and gaskets, but no cylinder head - so you can use it with your original cylinder head.

The increase in performance is noticeable in increased torque (due to larger displacement) and slightly higher top speed.

To exploit the full potential of this kit, you should opt for a sports exhaust.

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: Sport

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.

The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.

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.
