Intake Reed Valve - KAWASAKI

Boyesen intake reed valves are developed in collaboration with the world's best teams such as Yamaha Factory, Pro Circuit, Kawasaki Factory Europe, KTM Factory and some of the best riders of all time such as Jeremy McGrath.
These valves are produced with a redesigned housing in monobloc cast aluminium with Boyesen Pro Series reeds; this allows to obtain a much more homogeneous flow during the suction phase, which is sent much more directly into the burst chamber.
The kit is supplied ready to be installed and no engine modification is required.
