High perofrmance head porting ( camshaft not included )
G-force Division with the collaboration of J-Precision and DJ Engineering spent 100's of hours maximizing head porting for the YFZ450r to obtain maximum efficiency and maximum performance. In racing, the last HP found can make the difference. Multiangled and enlarged valve seats and port mod combined with regrinded oem valves makes intake charge at its best. Semi rigid finish intake port atomizes fuel and air at its max for more bottom end torque, and reshaped and sized for maximum top end power. Mx or endurance first place trophies were many times acompanied by G-Force Divisions heads.
Plan 10 buisness days for the modification of your head.
