Cylinder Malossi Testa Rossa 90cc DRR DRX

Malossi Testa Rossa Cylinder 90cc for DRR DRX 90 2-Stroke LC.

If you want to upgrade your bike, this is the ideal component as you will move to a displacement of 89.93 ccm, which means you will install a Cylinder designed with 7 transfers and a double exhaust port that will completely change how the engine works: it will reach higher RPM faster, maintaining power at the top and gaining a lot of torque throughout the range.

The removable cylinder head features new internal profiles designed to improve torque and make the engine more responsive to the throttle. In addition, the red anodized forged aluminium cover not only improves heat dissipation, but also gives it that characteristic finish of the Testa Rossa range.

The 1-ring piston reduces internal friction, allowing the engine to run more freely and reach higher RPM.
