Cylinder Kit Malossi MHR Replica 79cc Derbi Euro 3 / 4

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.
