New 70cc Polini Evolution engine for 2010 for Piaggio Zip - 25hp, Another engine and a new cylinder from Polini, things are definitely hotting up in Italy, what's going on?!
This new 47.6mm cylinder kit is set to give an enormous 25hp which should please the Italian cup riders along with young gun runners Sam & Josh in this year's BSSO Championship.
As you can see from the pictures the new 70cc uses the same cylinder layout as the 94cc big bore which will also be available soon. A new crankshaft, ignition and exhaust also make an appearance on the latest Evo incarnation with usual goodies assembled.
