The Secret Chassis Mod Factory Yamahas ACTUALLY Use
We’re taking the aggressive, hyper-responsive Yamaha YZ450FX chassis and giving it the ultimate factory handling makeover. Inspired by the setups used on the Monster Energy Star Racing Yamaha machines, we installed a longer swingarm configuration off of a 2017 Yamaha YZ450F and pressed in FCP Racing offset steering race cups to see if we can tame front-end twitch and gain high-speed stability without giving up cornering agility.
In this video, we walk through the full build, explain the geometry changes, and take it out for high-speed track and off-road testing.
