SR-VVT

Suzuki Racing VVT (SR-VVT) System developed for Moto GP racing. Unlike complicated variable valve timing systems used by other manufactures, the SR-VVT is simpler, more compact, lighter and more positive. The centrifugally operated system is built into the intake cam sprocket and an adjacent guide plate, using 12 steel balls and slanted grooves to rotate the sprocket and retard the intake valve timing at a pre-set rpm, adding significantly to high-rpm power.
