Cylinder kit Metrakit 80CC Pro Race 4 Derbi NT 2006 D50B0

The new Metrakit cylinder!

Finally, it's here. The new Metrakit Pro Race 4 cylinder. Based on past results, this is a cylinder we have been eagerly awaiting. And it's not for nothing. Metrakit has once again outdone itself with the new Pro-Race 4 cylinder. The perfection in finish, and the high-quality material makes this cylinder truly worth every penny.

Do you want to upgrade your derbi and do you want an 80CC cylinder with a good price / quality ratio? Then we definitely recommend this cylinder. The crankcase of your Derbi does not need to be modified. A reinforced crankshaft is a plus. We do recommend you to install a larger carburetor (for example from the Polini CP series). To get the full power out of this cylinder, it is best to install a Big-Bore exhaust (for example SCR Corse or Voca). Your Derbi will also need to be re-adjusted.
