- KIT POLINI EVOLUTION BIG " For Minarelli and Piaggio BORE 52 MM.
Polini has designed a new cylinder kit for Minarelli and Piaggio engines designed exclusively for racing on the track as it is characterized dall'alesaggio increased by 52 mm. This is a specific kit that seeks to satisfy the numerous requests for drivers and fans eager to have a motor very handsome "kitto" with extraordinarily high performance processing.
SPECIFICATIONS: Cylinder casting alloy. System "Closed Deck" for internal flow of the coolant. Bore 52 mm. - Race 44 mm. - Biella special 85 mm. - Displacement 94 cc cylinder liner with nickel-chromium. Five transfer ports plus an exhaust port stud for a more efficient evacuation of combustion gases. Diagram of very high performance. Piston gravity cast alloy with high silicon content in a segment chrome alloy cast iron Head cast by gravity in one piece. Combustion chamber and squish specifically designed to eliminate problems of detonation. Before installing the bore kit is essential that the guard is in the drive shaft in the housing of the cylinder. Polini has also designed an exhaust system specifically for this type of engine and a crankshaft with 44mm stroke.
- CLUTCH POLINI "SPEED CLUTCH 3G" E "3G SPEED CLUTCH FOR RACE FOR SCOOTER 50 cc.
The new Polini Speed \u200b\u200bClutch 3G for the various 50 cc scooter on the road is available in two models: base and FOR RACE. They differ as to ensure greater recovery, more acceleration in stretching, burning starts. Cope better with stress and the stress of standing starts. The clutch base is delivered with a specific calibration for the original engine. For races on the track can be easily modified by replacing the springs. The clutch is adjustable and model FOR RACE can be calibrated for the best setting for city driving or for racing on the track. The adjustment is made on the register spring with a simple Allen wrench.
TECHNICAL : Geometric tolerances are very tight which allowed us to produce a clutch perfectly balanced. Mix of friction material with aramid fibers and resins technologically advanced. Clutch more modular and more resistant to higher temperatures and abrasion.

-KIT "HI-SPEED" POLINI
absolute novelty is the addition of the spring with EVO-SLIDER. The EVO-SLIDER Polini, made of wear resistant, self-lubricating composite material, allows the compression spring to flow in steadily eliminating torsional stress of the spring. In most favors the flow and progression of the contrast on the cam pulley. This makes the scooter more rapid change and constant over time.
Although the displacement of 50 cc scooter remains the same, will seem to drive a new model: the more gritty and brilliant at the start of power. And if the scooter is prepared for the races on the track? No problem: with a few modifications you can customize the performance of your kit HI-SPEED for example, changing the weight of the load of the spring rolls and contrast thanks to the many alternatives that you can find in the catalog Polini.

It perfectly combines superior performance, optimization of power at each speed, high reliability, maximum mechanical strength.
FEATURES TECHNICAL: The expansion of type "racing" is made of special steel P04 low-carbon material capable of providing high resistance to stress. The welding of the cone shells are made using the highest quality system for TIG. E 'has been studied for the characteristics of liquid cooled "code" of 50 cc and those cast for the racing. The silencer, direct exhaust, is in light alloy.
