Cylinder Malossi Testa Rossa 100cc Derbi euro 3-4

Malossi Cylinder Testa Rossa 100cc for Derbi euro 3-4.

As expected, the manufacturer Malossi has already updated its famous Testa Rossa Cylinder for Derbi euro 3-4, a 47mm stroke with a displacement of 100cc, undoubtedly one of the best currently on the market.

According to Malossi engineers, with the entire kit on the test bench it delivers more than 32hp at 14,000 RPM. How did they achieve this? By modifying the cylinder, increasing the transfer ports to a total of 7, and the removable cylinder head and insert have had several parameters changed to increase compression and extract maximum performance.

On the other hand, it should be noted that you must install its crankshaft with a 47mm stroke, reference 5318895, and its exhaust reference 3220038.

We recommend installing a minimum 32mm carburetor, the Malossi exhaust designed for this cylinder, Vforce reed box, and Voca Racing transmission.
