Crankshaft, SIMONINI connecting rod 44mm stroke 85mm axis Ø12mm MINARELLI Horizontal scooter (nitro, aerox, ...)

Crankshaft for scooter MINARELLI horizontal air or liquid engine. Special long stroke 44mm (against 39.20mm for the origin), rod length 85mm (against 80mm for the origin) and axis of diameter 12mm (against 10mm for the origin), it can only be installed with a kit provided for this purpose like the SIMONINI racing booster Ø47.6mm special long race.

Otherwise, you can also install it with a kit for racing and normal connecting rod! However you will need to put a shim of + or - 7.5mm (2.4mm for the increase in stroke and 5mm for the connecting rod length), be careful to install a cylinder which originally has very low diagrams ( 125 ° / 185 ° max) because they will be greatly increased with this race. It is made with very high-end materials, has very reinforced foot and big end bearings with an excellent lubrication passage system.

The connecting rod is also extremely reinforced. However, in order to install it, you will need to have the engine housings machined because the long stroke takes up space. Even the masses are calculated in relation to the stroke of the piston and it is very well balanced. Genuine high-end material Made In Italy. The crankshaft bristles (location of the bearings) are of the original size Ø20mm.

Delivered without ignition key or bearings, the keying is readjusted and corrected in relation to the long stroke. Needle cage supplied Ø12 X 17 X 15mm.
