This crankshaft is all simply beautiful, it is equipped with a very expensive and beautiful rod forged and cut in the mass of aeronautical materials. It has a stroke of 44mm which will offer you no less than 87cc coupled to the 50mm MHR BIG BORE diameter kit. Attention with its 13mm piston pin, it can be mounted with the 87cc MHR BIG BORE kit. It is really well balanced and has nothing to do with other crankshaft ... Its price is explained both by its materials that cost a fortune than by the study that had to be done to get out such a racehorse.

PREPARATION OF SEMI-CARTERS

for Art.5313275: Bore the 2 half casings with a diameter of 76.5 mm in order to insert the crankshaft.

This crankshaft has been projected with the semi shaft on the transmission side increased to be able to best use their potential. Inside the assembly there is therefore a hub, a dimmer cap and a spacer that must be substituted for the Malossi MHR or over range variator in order to correctly mount the crankshaft.
