Bidalot Racing RF50WR Cylinder 50cc Minarelli AM6 c.39

Cylinder Bidalot Racing RF50WR 50cc c.39 for Minarelli AM6.

The Cylinder Bidalot Racing RF50WR of 50cc for Minarelli AM6 is the ideal option if you are looking for an adaptable kit that does not require you to change the crankshaft. Unlike the Racing version, this model is designed to be installed with an original stroke and connecting rod length crankshaft, making installation easier and reducing the need for adjustments.

This cylinder has been optimized for daily use, reducing the port heights and compression ratio compared to the Racing version. This makes it less sensitive to setup and peripheral components, offering reliable and consistent performance.

Thanks to its 3D CAD design, the water passage surrounds all the transfers, maintaining a stable temperature and ensuring the durability of the cylinder. The cylinder head, with heat treatment, also features a water passage that surrounds the combustion chamber, efficiently dissipating heat. In addition, it self-centers in the cylinder, entering 1.1mm into the inner diameter.

The exhaust nozzle is fixed with 4 screws, and you can purchase separately nozzles of different dimensions (Ø28mm, Ø30mm, Ø32mm) to adapt almost any exhaust on the market.
