Bidalot Cylinder RF70WR 70cc Minarelli AM6

Cylinder RF70WR for Minarelli AM6 70cc Bidalot.

Modified cylinder defining new transfer and exhaust cores, adapted to its 70cc displacement.
These cores have been studied to provide high performance at high revs, without penalising torque and power at mid-range.

The water channels have been improved, surrounding the charge and exhaust transfer, with constant thicknesses to ensure stability and achieve optimised cooling.

They have improved the cylinder head, heat treated, achieving better dissipation and cooling of the engine. It is self-centering with 2.4mm.
The nozzle / exhaust connection is 4 bolts. However, it is possible to mount a nozzle with 2 holes, with a centre-to-centre distance of 48 mm.
