POLINI 177 cast iron Cylinder: the old-school classic as the benchmark in the 177 cc class.

With this classic, POLINI continues to set the reference point by which cast iron cylinders are measured. Even as a plug-and-play Cylinder, it impresses with powerful pulling power from low revs and a clean gear connection. Seven flow-optimized transfer ports with a three-part boost port, a generous outlet and the solid ASSO Piston form the robust basis. In conjunction with a 60 mm Long Stroke Crankshaft, the displacement increases to 187 cc.

• Robust cast iron construction: stable and suitable for everyday use
• Powerful torque: good pulling power even at low engine speeds
• Strong layout: 7 transfer ports + three-part boost port, generous exhaust
• Tunable: 24/24 SI Carburettor, Racing Crankshaft and suitable peripherals significantly increase the potential

With a longer gear ratio, the Cylinder is ideal as a touring setup. For more power, you can switch from the 20 mm Carburettor to the 24/24 SI, combined with a Racing Crankshaft. Additional performance and reliability can be achieved with a combustion chamber and compression-optimized MMW MALOSSI Cylinder Head and the GRAND-SPORT 177 Piston. With a large Racing Exhaust, Carburettors up to 30 mm and a machined exhaust, high engine speeds and Vmax values of up to 125 km/h are possible - provided the setup is properly tuned.
