Cylinder Kit 50Cc Motoforce Black Series Derbi Euro 3 / 4

Cylinder Derbi Cylinder 50cc "Black Series" Derbi Euro 3 / Euro 4 (D50B0) like Derbi Senda, Gilera RCR or Aprilia RS replaces the expensive and lower quality original cylinders. Performance and Design The cylinder follows OEM specifications and is therefore identical to the original. 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. All other components such as gaskets and pistons are also the same as the original. Compared to even cheaper aftermarket cylinders in OEM quality, the Black Series kits are characterised by a very clean finish and excellent precision. The cylinder does not produce more power, but it can deliver this power over a longer period of time and lasts longer. All in all a very good, durable cylinder for little money.
