TUNING RACE – for professionals Product description
The EVOLUTION series comprises the complete product area at POLINI a series made only for the hammer hard racing scene. The same rules apply as for the MALOSSI MHR series: this series is only for those who have enough background in technical know how and also have the ability to pilot highly tuned vehicles. There is a great deal of potential in this range of high end tuning, and know how and capabilities are necessary in order to make use of it. We have a range of products from POLINI, 50cc and 68cc cylinders, as well as variomatics, crankshafts, exhaust, belt pulleys, ignitions, carburetor kits, Speed Drives, clutches, fan belts and reed valve blocks. This is the successor to the legendary POLINI Evolution Cylinder. POLINI has put their entire know how in developing this new kit. 47,6mm bore/3-piece outlet/enlarged boost port/ higher valve timing. According to POLINI, the Evolution II Cylinder, when used with the right components, can get performance of around 21 horsepower! The Evolution II should be paired with a racing crankshaft, an absolute necessity to prevent damage. Technical data 47,6 — 13.40021-P1660107
