partnumber P2100034

Delivery time: 1-2 days, Express 1 day*
To compliment the new Polini reed Evo kit there is aspecial racing crankshaft available. The finish and look of the crank leaves nothing to be desired. The massive research and development of Polini shows the elaborated balancing of the crank webs. Opposite to the big end you see Tungsten balancing weights. The holes beside the big end pin are filled with resin. The result is a very smooth running and well balanced engine and less power losses in the crank drive.
Sufficient lubrication holes and slots and best racing big end bearing gives a reliable and long lasting crankshaft. The CNC finished con rod is strong and massive.
The full circle crankshaft is perfectly suited for all barrels fed by a reed inlet direct into the cylinder. This Polini crank is designed for the Italian racing series hence the unusual 52.8 mm stroke. The con rod length is 102 mm instead of the standard 97 mm. The casings have to be machined to make the larger outer diameter of the crank web fitting.
