Description

Details

For the BigEvolution 94cc, which has a bigger stroke of 44mm instead of 39.3 (Minarelli: 39.2) mm, Polini offers a fitting crankshaft with 85mm conrod. The bore of the BigEvolution 94cc is 52mm, i.e. 2mm more than Malossi's BigBore cylinders, which is basically as far as you can go before you get into trouble with the cylinder studs. The outside shape is the same as the one used for the new Evo4 cylinders. If you want more and don't mind working the crankcase, we recommend the 94cc version in conjunction with a 44mm long-stroke crankshaft with 85mm connecting rod, which will yield performance in the upper 20hp region.
Attention: Only suitable in conjunction with the Polini Evolution variator.
