Product information "Cylinder kit Polini BIG EVOLUTION - Minarelli AM6 - &slash; 52mm stroke 44mm"

Only for Racing! Not homologated!

The Polini Big Evolution Minarelli cylinder kit is characterised by a displacement of 94 cm³ with a bore of 52 mm and a stroke of 44 mm.

The cylinder kit is manufactured using racing-proven technologies.

The cylinder has an optimised distribution diagram that guarantees maximum power in the upper and middle rev range. This feature allows it to be used both on kart tracks and in the most extreme off-road competitions. The nickel-silicon coated cylinder has 6 intake ports and an exhaust port with a marker to control thermal expansion.

The piston is equipped with a 13 mm diameter piston pin to ensure the high performance of the engine. A special flange made of billet aluminium is used for mounting on the original crankcase, which requires no modification to the fairing or fitting.

The exhaust flange of the cylinder is designed for the Evolution muffler with low passage, so that the ideal cone size can be utilised for maximum performance. The rear silencer is made of black anodised aluminium. The silencer package includes a complete set of screws and brackets for easy installation according to the different chassis models.

Polini supplies a raw steel exhaust flange in the cylinder kit to adapt exhaust systems developed for engines over 90cc with original cylinder connection.

Important note:

The cylinder kit can only be installed in combination with crankshaft POL2100069!
