New .12 & .21 piston design from Sirio

New .12 & .21 piston design from Sirio

Through a partnership with a company specializing in fluid dynamics and computer modeling, Star Motor Engineering have engineered these new .12 and .21 on road pistons that has the best performance possible. Under patenting, this new part is in the advanced stages of testing by team drivers and will soon be available in all racing products made by the Italian company. The new design claims to give better balancing of moving masses, ensuring more RPM and less mechanical stress on the crankshaft and bearings, better thermal efficiency due to less thermal inertia and finally lightening of the part limits inertia during acceleration which improves the rpm at maximum speed.
