Cylinder kit Malossi MHR Replica 80cc Derbi Euro 3 / 4 (D50B0)
Very powerful yet suitable for everyday use cylinder made of aluminum with a high-strength chrome/Nicasil-coated sleeve. Advantages of aluminum cylinders are improved heat dissipation and consequently better cooling.
MHR Replica cylinder design
The MHR replica cylinder has an oval outlet which ensures good torque and good acceleration. Thanks to two additional boost ports, the cylinder also has plenty of power in the upper RPM range. The usable RPM range is therefore relatively wide, with a power output of between 9000 and 12000 rpm depending on the exhaust you pair it with. We recommend exhausts such as Stage6 Streetrace or similar.
In order to make the cylinder more suitable for everyday use, Malossi uses a 2-ring piston, the bore is chrome-Nikasil coated as usual. Torque and power are really convincing, 10 - 14 hp are possible, provided you have the right setup.

Note: Models with Derbi Euro 4 engines use a slightly smaller temperature sensor (thread: M12 x 1.5) than the Euro 3 models (M14 x 1.5). To fit the smaller Euro 4 sensor to the cylinder head, you also need the MF96.91010 adapter.
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: 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.
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.
