Yamaha YFZ450R and Grizzly 700. Big Changes for 2014!
The wheels have been designed with the inner lip rolled in. This increases the rigidity, allowing a reduction in weight while maintaining strength. The wheels are set for motocross-spec width at nearly 49 inches for great cornering. Its Maxxis® tires are designed to help provide excellent handling, sliding control, and traction. At 20 inches in the rear and 21 inches in the front, they provide much better ground clearance than the competition – a benefit on rough tracks and trails. The YFZ gets excellent stopping ability, from dual front hydraulic disc brakes and a lightweight wave-type rear rotor.

The YFZ450R has large diameter, aluminum tapered handlebars that reduce vibration and are mounted on fourway clamps for adjustability. There are two sets of holes in the handlebar crown and the eccentric clamps so the rider can choose the standard setting, 10mm or 20mm forward, or 10mm back.
New heel guards provide more room and are positioned closer to the chassis for a slimmer feel, while the vehicle’s foot pegs are a generous 2.6 inches wide providing grip and stability even on tough terrain.
The frame is a combination of aluminum and steel for the best balance of light weight and rigidity. The frame member under the engine is steel, used for its combination of strength and low profile. This allows the engine to sit at its lowest possible point for excellent mass centralization and unmatched handling. The aluminum frame is bolted together, rather than welded, for maximum durability.

The rear swingarm with 11 inches of travel is crafted of strong, gravity-fed aluminum, and it is matched to a fully adjustable 46mm KYB® piggyback shock absorber for excellent handling.

The new front KYB® shocks with 9.8 inches of travel and Kashima™ coating are longer for increased suspension stroke with superb bump absorption and excellent anti-bottoming characteristics.
The front frame is as narrow as possible at the A-arm mounting points. This dramatically increases the A-arm length, which reduces changes in camber as the suspension travels through its full range of motion.
