Bore diameter is 50.5mm now, and to match the new dimensions, the cylinder features a 7 transfer port layout; the bridged exhaust port is supported and relieved by boost ports. The 3D CNC-machined cooling system provides optimum cooling and operational stability. 

The cylinder head is made of HQ aluminum (7075), the cylinder head cover is also CNC-machined and comes with a stunning looking matte black finish and Bidalot logo; it has an M10x1.00 opening for a temperature sensor and comes with a small plug to close it for use without sensor. 

The cylinder is meant to be used with a 4-hole exhaust flange, but can be used with a regular 2-hole flange as well (50mm spacing).
