Having six speeds in the CRF450X’s transmission compared to an MX bike’s typical five gives you more choice, and makes this versatile bike even more versatile. You have a gear for everything from east-coast rock crawling to wide-open Baja blasts.
Light, compact, and offering excellent performance—just like the CRF450X itself! Conventional batteries are heavy, but not this premium piece. It’s all part of why your new CRF450X performs as well as it does.
The CRF450X gets a special crankshaft, different from our CRF450R MX bikes and our CRF450L dual-sport. Why? The crank’s weight and inertial character make a huge difference in how a bike delivers power. A crank is expensive, but it’s no place to scrimp and try to save—with the CRF450X, power delivery is just what you want.
The CRF450X’s dual radiators feature a refined core area for superior heat dissipation compared with conventional dual-radiator designs. A coolant recovery tank is located in front of the engine between the frame downtubes for improved center of gravity, and the tank is protected by a plastic skid plate.
Holding 2.0 gallons, the CRF450X’s premium titanium tank is light and tough.
The CRF450X’s factory skid plate is light, yet also offers the engine and lower-frame protection serious riders demand on a machine like this.
Your CRF450X comes equipped with a complete lighting package (headlight and taillight) for riding at dusk.
