Cylinder kit Stage6 Big Racing 77cc Derbi Euro 2

Stage6 has dedicated itself to the development of high-performance tuning parts and is constantly taking on new challenges, which is why they are now also producing cylinders for 50cc supermotos. For Derbi Euro 2: Stage6 Big Racing 77cc cylinder kit.

Design Big Racing cylinder for 50cc motorcycles

The cylinder was developed in close cooperation with the professionals from MXS Racing. On the one hand, it was possible to benefit from their experience in the field of manual transmission mopeds and, on the other hand, to use their own technical know-how, which enabled the Stage6 engineers to develop a thoroughly successful and innovative tuning cylinder.

Visually, the BigRacing keeps a low profile, but appearances can be deceiving. This is a true big bore aluminum cylinder – not just a bored-out standard version. It was designed from the ground up as a genuine big bore kit, featuring matched transfer ports and a large exhaust port that effectively supports the increased performance.
