Cylinder Kit Black Series Derbi Euro 3 (D50B0)

Technically speaking, this Black Series Derbi Euro 3 it is an OEM quality kit, meaning it follows OEM specifications and is therefore identical to the original (but available for a bargain!). Just like the original, the cylinder is made of cast iron, it has the same number of transfer ports and the shape of the exhaust port is identical as well.

The piston coming with it is also identical, it has 2 piston rings (pin and circlips included), the gaskets are the same, too (cylinder base, cylinder head and, depending on model, exhaust gaskets). The Cylinder Kit "Black Series" Derbi Euro 3 does not include a cylinder head, you can mount it using the original one without having to modify anything.
