Crankshaft Bidalot RF50WR Minarelli AM6 stroke 39.7mm connecting rod 85mm

Crankshaft Bidalot RF50WR Stroke 39.7 connecting rod 85mm for AM6 engines. This crankshaft is specifically designed to operate the Ø40mm RF50WR cylinders from the manufacturer Bidalot (11000568 and 11001568).

The stroke is 39.7mm, and it is equipped with the new 85mm forged connecting rod, with CNC external contour, to control and guarantee the thickness around the head and the small end.

The connecting rod has a diameter of 18 mm, and the big end needle cage has been specially made according to Bidalot's plans. It is a narrower cage (Ø18xØ24x11.8) to increase the adjustment width of the connecting rod in the crankshaft webs (1.5 mm on each side), thus considerably increasing the rigidity of the crankshaft.

Specifications:

• Crankshaft webs machined from forged pieces.
  
• Forged connecting rod, CNC bypass, 85mm.
• Lower needle cage, silver-plated, with free needles, Ø18xØ24x11.8.
• Racing piston cage Ø12xØ17x15
• Hollow metal side friction washers.

Attention! You must carry out balancing checks before installing in the engine, since manufacturers deny warranty for any balancing fault found after installation.
