2014 Yamaha YZ450F
The new Yamaha YZ450F has a rearward-slanted-cylinder design, a four titanium valve cylinder head with a new fuel injection system. It also has a compact frame for the engine, smoother shifting and a new Bilateral Beam frame. The Yamaha YZ450F has reduced vibrations by adding rubber handle bar mounts which will also increase rider comfort.
Yamaha looks to improve its lot in the 450 motocross ranks with a significant revamp of its YZ450F. MotoUSA tester Chris See puts it through the First Ride paces at Zaca Station.
