The KFX®450R is Kawasaki’s sport ATV flagship! Sitting low to the ground on its adjustable suspension with long front A-arms, the KFX450R employs a lightweight and strong aluminium frame and five-speed transmission with reverse to harness the power from its fuel-injected, electric-start engine. Its impressive power and handling allows riders to maximize their performance on the track or in the woods.
The race-ready, high performance credentials of the KFX450R begin with a powerplant that’s based on Kawasaki’s highly acclaimed KX™450F motocross engine. It’s fitted with an efficient and highly-responsive 32-bit digital fuel injection (DFI®) system that automatically compensates for temperature or altitude. DFI also enhances the KFX450R’s ability to translate its four-stroke power into outstanding thrust, with easily accessible torque in the low and medium rpm ranges. A lightweight titanium exhaust header pipe and a durable forged piston further refine this 449cc engine’s usability and longevity.
The fast and reliable KFX450R also includes a lightweight reverse gear system integrated with its five-speed manual transmission. The KFX450R’s reverse gear allows riders to quickly and easily extricate themselves from first turn chaos, trail bottlenecks or any other on-track incident.
Built to handle tough trail conditions and win races, the KFX450R’s lightweight all-aluminium frame has both incredible stiffness and significant strength. The high-tech chassis also provides a low center of gravity and excellent roll resistance for higher corner speeds and race-level handling.
The front suspension design utilizes long lower A-arms mounted to a single box-section lower frame tube and paired with dual-rate front springs for excellent rough-terrain handling. In the rear, an adjustable shock with low- and high-speed compression and rebound damping adjustability is mated to a cast aluminium swingarm that offers the ideal balance of flexibility and rigidity. Regardless of track surfaces or conditions, this race-oriented chassis makes the KFX450R a potent weapon.
The KFX450R is easy to work on, so owners can spend more time in the dirt than in the garage. The two-piece front and rear “lapped” fenders make it easier to customize the size of the fenders or quickly replace damaged sections. Even the headlight assembly is quickly detachable for closed-course races—this ATV looks just as aggressive with or without headlights. These features leave little doubt that the KFX450R was designed to be on the track and winning races as quickly as possible.
Owners can customize their KFX450R, using a full line of Authentic Kawasaki Accessories from their local Kawasaki dealer.
