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

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!

Electric Start
Kickstarting your bike is so 2016. By ditching the kickstarter entirely, our engineers can make the CRF450RX lighter. Electric starters and lithium-ion batteries

Lighter Overall Weight
The CRF450RX 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.

260mm Front Brake
The CRF450RX’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

High-Capacity Resin Fuel Tank
For longer cross country loops, the CRF450RX features a bigger fuel tank that holds a full 8.5 litres.

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

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

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

Longer Head Pipes
Lengthening the CRF450RX’s headpipes help give you better throttle response and top-end pull.

Cylinder Head Layout
The CRF450RX uses our latest finger-follower rocker design. The Unicam cylinder head remains one of the most efficient in the off-road world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.

Programmable ECU
Want to fine-tune your CRF450RX’s power delivery to a specific riding style or course? It’s easier than ever with the CRF450RX’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

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.

Sidestand
Real enduro bikes need a sidestand, and we’ve given the CRF450RX a great one. Tucked up high and out of the way, this forged alloy piece is just another example

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 49mm Showa fork features a conventional spring design that helps increase the CRF450RX’s front-suspension precision, handling and feel. The spring rate provides better bottoming resistance and improved handling.

Next-Generation Aluminum Frame
The CRF450RX’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.

Swingarm
The CRF450RX's swingarm flex is finelly-tuned to work with the chassis and gives you better rear traction and comering precision.

Twin-Muffler Exhaust System
The CRF450RX’s dual exhaust system is light, compact, and positioned close and low in the frame to take weight off the rear
