Features may include: ENGINEERING New for 2020 Honda Selectable Torque Control (HSTC) The 2020 CRF450RX now features Honda Selectable Torque Control (HSTC), designed to improve the stability and traction while maintaining throttle position. With 3 settings to chose from you can have your bike dialed, no matter how much traction there is. Total Air Management By lowering the battery box position by 28 mm, not only has it lowered the centre of gravity but also allowed for a 9% increase in the size of the air filter. This allows for more responsive handling overall and improved airflowfrom intake to exhaust. HRC Launch Control We’re talking about a special and updated ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the CRF450RX will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine! PERFORMANCE 450 cc Unicam Engine Honda’s Unicam cylinder heads combine the best of single and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity. Dunlop Geomax Tires The CRF450RX’s Dunlop Geomax tires are specially designed for cross country use. The AT81 tires are spec’d at 90/90-21 for the front and 120/90-18 for the rear. You read that right: the CRF450RX rolls on an 18-inch rear wheel. Downdraft Fuel Injection The CRF450RX features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the CRF450RX offers such explosive power and massive torque, especially out of the starting line and in the critical first 30 meter (100 ft) of the race to the first turn. COMFORT & HANDLING Renthal “Fatbar” The aluminum Renthal® Fatbar® pushes the boundaries of riding excellence with its unmatched bend. Flat Seat/Tank Junction The CRF450RX features a flat seat/tank junction, including a titanium fuel tank. The superior ergonomics make it easier to move forward and back on the bike, increasing your control. Black Rims They may not help you go faster, but the black DID® rims this year sure look good.
