Description
The basis of the Big Evolution is still an aluminium cylinder with T-Port exhaust outlet and a six-transfer design.
What stands out most is the change on the "outside" of the cylinder: round shapes and additional cooling of the sides.
The cylinder head is now solid and does not come with a cylinder head. Another change has been made to the nozzle - it is now fixed with three screws!
So the Big Evolution cylinder has to be mounted with the matching Polini exhaust or a racing pipe from another manufacturer has to be fitted.
The bore of 47,6mm and the displacement of 70cc are in accordance with the current racing regulations.
Please note: The Big Evolution must be fitted with a crankshaft with an 85mm connecting rod!
Attention: 85mm connecting rod
