Engine & Electronics
True Street-Legal Dirt Bike
The CRF450RL uses the CRF450R motocrosser as a starting point, then adds everything required to make it fully road-worthy. From the CRF450R base, the frame was made slightly wider to allow for the 6-speed transmission, the engine was tuned for smoother power delivery, and the suspension and brakes were modified to make the bike more user friendly on tight trails and on the road.
Dynamic Performance
With a heavier crankshaft than used in the full-race CRF450R, you'll enjoy 13% more inertia from the Unicam engine, which means an even stronger feeling of torque when you twist the throttle.
Extra Durability
The CRF450RL’s Unicam engine shares the same bore and stroke as the CRF450R, but durability is improved thanks to the piston using three rings instead of one.
Wide-Ratio Transmission
The CRF450RL rocks a wide-ratio six-speed gearbox. That gives you a low gear perfect for tight, slow situations, and a top gear that’s tall enough to ride the highway to the next trailhead.
Built For The Long Run
You’ll find Honda build quality in every component of the CRF450RL’s engine, which translates into a real-world service schedule of 32,000 km between major engine maintenance, and air filter and oil filter change required only every 1,000 km.
Chassis & Suspension
Twin-Spar Chassis
The twin-spar aluminum frame is both light and stiff, and provides the basis for the CRF450RL’s excellent handling, making it a true off-road bike. Chassis geometry is specially engineered for responsiveness on even tight trails.
Showa Spring Fork
The 49 mm Showa fork features a conventional spring design that helps increase the CRF450RL’s front-suspension precision, handling and feel. The spring rate provides better bottoming resistance and improved handling.
Additional Features
Titanium Fuel Tank
Grams and performance count, and to keep the weight down, the fuel tank is constructed of titanium. Light and strong, it’s also thinner than our previous plastic unit, freeing up more space and helping to centralize fuel mass.
Fuel Mileage Meter
An important feature for planning gas stops and calculating your bike’s range under varying conditions, the CRF450RL’s fuel mileage meter shows current fuel mileage and average mileage as well as consumption. Displays in either kilometres or miles, and applies to both the A and B tripmeters. The meter is in the same digital instrument display as the speedometer, odometer, tripmeters and digital clock.
Lightweight LED Lighting
The CRF450RL features an all-LED lighting package — including the headlight — to help keep weight as low as possible. The lighting pattern is specially designed for both on- and off-road situations.
Alloy Sidestand
A sidestand may seem like no big thing, but take a look at the one on the CRF450RL. Tucked up high and out of the way, this forged alloy piece is just another example of how the CRF450RL gets it right.
New Hand Guards
When the going gets extra tough, you’ll appreciate the new hand guards added to the CRF450RL for 2021.
