Name Polini Cylinder Kit "W" 70cc aluminium d=46mm MBK 51 AC Item No. P134.0300 Brand Polini Homologation No Displacement 70cc Stroke Original Conrod Length Standard Product Line Racing Material Aluminium Engine Type 2-stroke Cooling Type AC Bore 46 mm Piston Pin Original Number of Piston Rings 1 Cylinder Head Not included
Polini 70cc Cylinder Kit &quo;Alu W&quo;, d=46mm MBK 51 AC with hard-chrome coated aluminium cylinder and single-ring piston. Cylinder head is not included!
The kit has impressive power at mid to high rpm range (appr. 7.3hp at 7700rpm, according to Polini) and lots of torque. Its unique feature: the W-shaped exhaust port.
We recommend combining the Polini 70cc Cylinder Kit &quo;Alu W&quo;, d=46mm MBK 51 AC with a 15mm carburetor (at least) and a high-rpm sports exhaust. Even though you can use this kit with the original cylinder head, we recommend replacing it with a high-compression cylinder head (46mm) to improve performance.
