Crankshaft Stage6 R/T 85/12mm - Minarelli MA

The Stage6 R/T crankshaft was developed as the perfect complement to the Stage6 R/T 70cc cylinder for Minarelli horizontal, but can of course also be used with other racing cylinders with 85mm connecting rod length. You can also use a cylinder kit with 80mm original connecting rods, in which case a 5mm cylinder spacer must be used. Plug & Play installation - the Stage6 R/T shaft can be installed without further modifications, without the need for complicated crankcase machining. We recommend using a set of new crankshaft bearings.
