CRF450RX 2021



Just like the CRF450R, the CRF450RX has a new frame, steering geometry and suspension setup developed directly from HRC's race bikes, so you can go in harder and come out faster. The engine also features more power with smoother torque delivery controlled by hydraulic clutch. The 3-Level HRC Launch Control gives you options out of the gate whatever your riding ability or experience, and whatever conditions you're riding in. And once you've bossed the start, 3-Level Honda Selectable Torque Control (HSTC) keeps you driving forward.

With the CRF450R MX machine as a base the CRF450RX already has an advantage and, along with its enduro-specific equipment – larger fuel tank, 18-inch rear wheel and sidestand. A completely new frame saves weight and features factory-rider rigidity balance with sharper steering, extra ground clearance and RX-specific suspension settings. The seat unit is smaller (and lower at the back) and new plastics are slimmer, lighter and easier to move around. For stronger mid-range power and smooth throttle response, the engine has a redesigned intake, cylinder head and exhaust while a revised decompression system minimises stalling. The new hydraulic clutch is tougher, with lighter lever load. HRC Launch Control owns the first 100 metres and HSTC manages rear wheel traction over a lap.
