Crankshaft with 39,3 mm stroke (original stroke) and 85 mm connecting rod for Minarelli horizontal engines (Yamaha Aerox, Malaguti F12 / F15 and many more) from Italian tuning expert Ottopuntouno (8.1).
This is a high-end racing crankshaft made of high-quality steel, with 85mm connecting rod and 18mm crankpin. The crankwebs have a diameter of 75 mm, perfect balancing of the crankshaft is achieved by tungsten inserts. Construction and balancing are perfectly designed for the 70 cc cylinder 8.1 from Ottopuntouno. The crankshaft was developed for use with an OttopuntoUno cylinder, but can of course also be used with other 70 cc or 80 cc cylinders.
The R-18 version is designed for installation in a standard Minarelli horizontal crankcase (original / OEM quality), but the case must be slightly milled to make room for the larger crankwebs.
Crankweb diameter: 75mm
To ensure optimum performance, we recommend using high quality crankshaft bearings Stage6 by SKF.
Crankweb diameter: 75 mm
