Fatigue can sometimes be a racers worst competition. Thats why the YFZ450Rs designers made this ATV so comfortable.

• Chassis/Suspension:

The chassis is very spacious, allowing room for even an aggressive racer to move around during the moto, and the ATVs body panels that the rider contacts during operation are of a softer plastic material for greater comfort. The seat is narrow in the front, yet wide and padded in the rear to provide a more comfortable ride, even when hanging off on the side of the seat in a turn.

Wheels are set motocross-spec wide, near the maximum allowable 50 inches, for great cornering ability. The Dunlop tires are grippy with a great pattern for cornering, and at 20 inches in the rear and 21 inches in the front, provide much better ground clearance than the competition. That makes the YFZ450R fun to ride off-road, too.
