After the radical makeover received in 2010 the Yamaha YZ450F continued to receive small upgrades which help it remain on the same line with its rivals. The year 2012 brings a series of small upgrades as well. The most significant modifications were made to improve the ride, smoothen the gearbox and to give the engine a better response.
To help the bike absorb bumps easier, Yamaha gave it a new set of valves which help the suspension to deal easier with the difficult parts of the track thus transferring fewer vibrations to the saddle.
The engine’s modifications were kept to minimum and the unit received a more rigid shift fork to improve the transition between second and third gears. There were also made a few tweaks to make the throttle smoother and to increase its response in the low-mid range.
The engine is mounted on an aluminum double “S” bend Bilateral Beam frame which is perfectly suited for off road driving.
