This allows the engine to sit lower overall to centralize excellent mass for unparalleled handling. The aluminum frame is driven together, rather than welded, for maximum durability.

Suspension Long A-ARM: The front frame is as narrow as possible at the A-arm mounting point. This increases the length of the arm A and reduces Camber’s change as a suspension of travel through various movements.

Rear suspension swingarm: Rear Swingarm is made from strong, gravity-fed aluminum, and is suitable for fully adjustable 46mm KYB® support shock for excellent handling. The rear-wheel-drive is 11.0 inches for convenience even in tough terrain.

Aggressive SE Style: Aggressive styling gives the YFZ450R SE a customized upbeat, with additions like GYTR® grab the front Bar to match a unique graphics package.
