Vespa - Cylinder Kit - Polini - 135cc Evolution

Alloy with new design Cylinder Head

Reed Valve Induction

57mm Bore

Polini has designed a new Evolution kit with reed valve induction. This creates an engine that is really powerful in every kind of driving condition including racing. The "Reed Evolution" kit includes cylinder, piston, head, reed valve intake manifold and a gasket kit.
The reed valve has 6 carbon flaps on 0.4mm thicknessand the geometry of the flow guide allows it to improve the air-petrol mixtures incoming speed.
The intake manifold has been developed to be matched with the PWK polini carburettor (Available to order in 3 different sizes 24/26/28mm) To be able to fit this kit it is a requirement to bore the crankshaft housing within the case, and change the crankshaft from standard to a Polini Evo full circle 52.8mm stroke crank 
By fitting these parts you achieve a most out of the 135cc of displacement according to the sprint scooters races' rules.
It can be used with the Polini muffler Listed
Or to achieve the maximum performance it should be assembled with the Polini Evolution 2 muffler 

Technical Features
Cylinder is cast aluminium.
The liner with Nickel-Siliceous coating improves piston sliding its resistance to wear and abrasion.
The transfer ports are designed for racing. It has 6 transfers. The transfer has a central bridge for better exhaust gas scavenging.
The piston is gravity cast in light alloy and it has two "S10" chromed cast iron rings.
After its working the piston has been covered with special molybdenum-bisulphide coating that improves the piston sliding during the running in period.
The head is cast in one piece only and some fins have been made under the head plane in order to improve the heat dissipation.
