King of the 177cc class. POLINI sets the
standards with this old school classic, the one all cast iron cylinders have to
measure up to.
At the plug and play level, this is a powerful cylinder, and with a 60mm long
stroke crankcase, can reach 187ccm - incredible! 7 powerful transfers with a
triple boost port feed the cylinder. A generous exhaust and solid ASSO pistons
create a solid support.
Power plus starts in the lower ranges. No problems here with shifting. With a
longer transmission can operate well as a touring cylinder. If you like, the
20mm carburetor can be replaced with the big brother 24/24 SI, and at least,
mount a racing shaft. More power and dependability can be yours by adding
combustion chamber and compression optimized MMW MALOSSI cylinder head and the
GRAND - SPORT 177ccm piston. A larger racing exhaust, carburetor up to 30mm and
a modified outlet will pump up your performance even higher, max around 125
km/h, and bring tears to your eyes.
Results: Robust, hefty torque cylinder for daily use.
An absolute all-rounder.
