It’s no wonder why the Kawasaki KFX450R was the overall winner of the 4-Wheel ATV Action Magazine’s 450 Sport Shootout.

The KFX450R ATV uses a powerplant based on Kawasaki’s highly acclaimed KX450F motocross engine, that rocks a killer engine with 43 hp and 31.1 foot pounds of torque with chrome composite plated material cylinder. The engine is based on the engine from the World Championship winning KX 450F. The forged piston has a low friction coating and a larger diameter wrist pin for increased durability.

Kawasaki KFX450R ATV Engine Features

• Electric starting facilitates quicker stall recovery and lowers rider fatigue.
• Large-volume airbox contributes to both intake efficiency and the sharp engine response. An air duct fashioned from polyethylene (known for its ability to resist deformation caused by intake pulses) helps ensure stable engine performance.
• Torque delivery is tuned to match the rear tires’ ability to deliver traction, making it easier to accelerate without excessive wheel spin. Efforts were made to achieve the widest possible torque curve, so that traction can be maximized through a greater part of the rev range.
• Asymmetrical high-acceleration cams yield high intake efficiency.

Kawasaki KFX450R ATV Transmission Features

• The five-speed (one-down, four-up) manual transmission locates the reverse gear below first. Actuating the reverse-lock release lever when in first gear allows you to shift “down” into reverse
• Compact reverse-lock release lever can be activated with the right thumb, allowing the reverse gear to be engaged while still keeping the front brake lever depressed
• The combined weight of the reverse gear system and the lightweight aluminum chassis is no heavier than using a steel frame without reverse

Kawasaki KFX450R ATV Chassis Features

• Highly rigid aluminum frame contributes to the KFX’s excellent handling and traction. The frame’s high torsional rigidity enhances stability in corners and allows the suspension to be easily set up to suit course conditions.
• Designed for high corner speeds, the KFX ATV sits low to the ground, helping to reduce roll tendencies.
• Mounting the battery and coolant tank in front of the engine lowers the center of gravity, and helps weight the front wheels for increased traction when cornering.
• Single box-tube lower frame contains the front A-arm attachment points. This design is narrower than the competition’s frames and enables the use of longer lower A-arms.
