For 2020, Honda's flagship CRF450R—the same platform raced by Team Honda HRC's Ken Roczen and Cole Seely—puts more engine-management choices at the fingertips of racers, with the addition of Honda Selectable Torque Control (HSTC). Developed through HRC's worldwide racing effort, the system maximizes rear-tire hookup to keep all of the Unicam® engine's horsepower driving the bike and rider forward, improving racing success regardless of track conditions. In keeping with racing-body regulations, the system measures rate of rpm increase and adjusts delivery accordingly, and a handlebar-mounted switch enables selection from three levels of delivery (most in class). In addition, the CRF450R's front-rear balance is refined and handling is improved thanks to internal suspension updates, and a new battery position that lowers the machine's center of gravity. Improved rear-brake pad performance and durability, and the exclusive specification of Dunlop Geomax® MX3S tires round out a machine that's ready to take riders to the next level.
2020 Updates
- All-new Honda Selectable Torque Control with three levels of intervention. HSTC monitors rpm spikes and responds by temporarily reducing torque to aid rear traction. A handlebar-mounted switch allows selection between three modes, depending on conditions and rider preference.
- Revised mapping for riding modes in Standard, Smooth and Aggressive options, selectable via a separate handlebar-mounted switch, enables simple tuning depending on rider preference or course conditions.
- Revised internal fork and shock settings for improved chassis balance and overall handling.
- Battery position lowered by 28mm moves center of gravity downward to further improve chassis balance and handling.
- New rear brake-pad material for improved performance and increased durability.
- Elimination of lower rear brake-rotor guard, to improve heat dissipation and reduce unsprung weight.
- Updated graphics.
Engine/Drivetrain
- 449cc single-cylinder engine with Unicam cylinder head, downdraft intake tract, electronic fuel injection and electric start offers unparalleled "Absolute Holeshot" performance.
- Selectable HRC launch control provides a steady stream of torque for excellent performance on race starts.
- Electric starter (powered by a lightweight lithium-ion battery).
- Shift sensor allows a dedicated ignition map for each gear, enabling optimum running.
Chassis/Suspension
- Twin-spar aluminum frame engineered for great traction and cornering feel, and to minimize weight.
- Chassis layout allows heavier components to be located as centrally and low as possible for nimble handling and feel.
- Front-brake caliper uses a pair of pistons (30mm and 27mm) for optimal braking performance on a 260mm rotor with a petal pattern to best dissipate heat.
- Showa® shock and 49mm coil-spring fork.
- Front brake hose resists expansion for precise, consistent braking feel.
- Top triple clamp has two handlebar-clamp locations for moving the handlebar back and forth by 26mm. With reversible handlebar clamp enabling an additional 10mm of adjustment from the base position, there are a total of four different handlebar positions.
- Black Renthal® Fatbar® handlebar encourages active riding position, while also contributing to light steering feel.
- Footpegs shed mud and give the rider great feel and confidence in all riding conditions.
- Lightweight, compact 1.66 gallon titanium fuel tank keeps weight to a minimum.
- Black D.I.D rims deliver a strong presence on and off the track.
- Minimization of lines and gaps in the plastic panels results in a smooth surface, facilitating riding-position changes.
- In-mold graphics are durable and resistant to peeling caused by washing or abrasion.
- Available only through Honda dealers, Dunlop Geomax MX3S tires provide superior bump absorption and excellent grip.
