Valve Springs MALOSSI
for MASTER engine for APRILIA
/PIAGGIO 400/500cc 4-stroke,
Valve springs are doing an important job: on condition that the appropriate push rods are used, these springs decide on how the valve will respond to the control commands of the camshaft. If the valve springs are too soft, the dreaded valve float can occur which might result in serious engine damages: grinding of the valve seatings into the cylinder head, damages at the valve shafts and valve collets, valve touching the piston in the worst case! Additionally, a floating valve cannot cool down as it should, thus making it prone to overheating.
Made from hardened titanium, the valve springs by MALOSSI are of unique quality. Heat-resistant, low-wearing and certified by the ISO9001 quality control, the MALOSSI valve springs provide maximum durability even under extreme forces. Ideal combination with a tuning cylinder and the icing on the cake in 4-stroke tuning
