  • New for 2020 Honda Selectable Torque Control (HSTC):: The 2020 CRF450R 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 airflow from intake to exhaust.
  • Improved Stability: The CRF450R features the Honda Selectable Torque Control that is designed to improve stability and traction while maintaining throttle position. Just another feature that makes your ride smoother and more controlled.
  • Total Air Management: By lowering the battery box position by 28.5 mm, the air filter size has been increased by 9% for improved air flow and total air management, efficiently managing the air flow through the intake, the head, and out the exhaust.
  • HRC Launch Control: We're talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the CRF450R will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
  • Lighter Overall Weight: The CRF450R is surprisingly light. Why? Mostly from eliminating the kickstart option, but weight is weight, and on a racebike less of it is almost always better.
  • Electric Start: Kickstarting your bike is so 2016. By ditching the kickstarter entirely, our engineers can make the CRF450R lighter. Electric starters and lithium-ion batteries are so light now and so good that putting them on a bike like this is a win/win combination. And winning is what a CRF450R is all about.
  • Titanium Fuel Tank: Grams and performance count, and the CRF450R uses a titanium fuel tank. Light and strong, it's also thinner than our previous plastic unit, while maintaining the same capacity, freeing up more space and helping to centralize fuel mass.
  • 260 mm Front Brake: The CRF450R's large front-brake disc measures a whopping 260 mm. The rear brakes have also been updated to improve overall braking performance. Now you get great brake feel and a pattern that cuts down on weight. Front and rear brake-disc guards are part of the package too.
  • Engine Mode Select Button: This simple handlebar-mounted button lets you dial in engine power delivery character with a push of your thumb. Choose between Standard, Smooth and Aggressive, depending on track conditions.
  • 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.
  • Downdraft Fuel Injection: The CRF450R features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It's part of the reason the CRF450R offers such explosive power and massive torque, especially out of the starting gate and in the critical first 30 meters (100 ft) of the race to the first turn.
  • Double-Spray Injector Settings: "The CRF450R's fuel-injection system sprays twice per intake cycle. That helps increase fuel atomization without adding the weight or complexity of a second injector. The better fuel atomization means more power in the midrange and on overrev—you'll feel it the first time you race. "
  • Longer Head Pipes: Lengthening the CRF450R's headpipes help give you better throttle response and top-end pull.
  • Dunlop MX3S Tires: Developed using Dunlop's latest “block-on-block" design technology, the CRF450R's MX3S tires give excellent feedback and are a perfect complement to the CRF450R's frame and suspension.
  • Cylinder Head Layout: The CRF450R uses our latest finger-follower rocker design. The Unicam cylinder head remains one of the most efficient in the MX world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.
  • 13.5:1 Compression Ratio: The cylinder head of CRF450R features a refined squish area that helps boost compression to an impressive 13.5:1. That means improved combustion efficiency for more power.
  • Programmable ECU: Want to fine-tune your CRF450R's power delivery to a specific riding style or track? It's easier than ever with the CRF450R's programmable ECU.
  • Skid Plate: A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.
Comfort & Handling
  • New Renthal® Fatbar®: The aluminum Renthal® Fatbar® pushes the boundaries of riding excellence with its unmatched bend.
  • Flat Seat/Tank Junction: The CRF450R 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 D.I.D® rims sure look good.
  • Next-Generation Aluminum Frame: The CRF450R's Next-Gen twin spar aluminum frame positions the rear shock's mounting point lower, opening up the airbox area and contributing to a lower center of gravity for more holeshots. The frame geometry also helps improve traction, feeling and steering precision.
  • New Suspension Settings: Not a big change, but hey, with a bike this good we're talking about chasing perfection. What you'll experience is better front/rear balance.
  • Showa Spring Fork: The 49 mm Showa fork features a conventional spring design that helps increase the CRF450R's front-suspension precision, handling and feel. The spring rate provides better bottoming resistance and improved handling.
  • Swingarm: The CRF450R's swingarm flex is finelly-tuned to work with the chassis and gives you better rear traction and comering precision.
  • Frame Members: With some of the rigidity taken out of the rear subframe, the chassis complements the swingarm to help maintain the bike's overall balance and feel.
  • Twin-Muffler Exhaust System: The CRF450R's dual exhaust system is light, compact, and positioned close and low in the frame to take weight off the rear end and bring more mass to the bike's center for improved handling. It also allows for more air flow, and that equals added power.
