Overview

450 cc Unicam Engine

Honda 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.

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.

50th Anniversary

In celebration of the 50th anniversary of Honda's first motocrosser, the 1973 Elsinore CR125M, A special 50th Anniversary CRF450R is available for 2023, turning heads at the track with some major style updates. Taking its cues from the 1980's CR250, the 50th Anniversary model comes with the 80's style blue seat, gold rims and handlebars, special graphics kit and the same triple clamps as the Works Edition model. It also receives specially designed white number plates and the Honda wing-mark on the front fender and radiator shrouds.

Hydraulic Clutch

Big power requires a strong clutch, and this bike delivers with a smooth-operating hydraulic clutch. The CRF450R ditches the cable for consistency, solid control and strong feel at the light lever. A generous clutch capacity maintains a focus on maximized power transfer and durability - without much slippage at peak power.

Electric Start

Kickstarting? Maybe if you’re riding in the vintage class, but not here. Our engineers have focused on creating a bike that is suprisingly lightweight. 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-series bike is all about.

Honda Selectable Torque Control (HSTC)

Honda Selectable Torque Control (HSTC) works to minimize rear wheel spin (thus wasted forward drive) and maximize traction. It doesn’t use a wheel-speed sensor, and, importantly, maintains feel at the throttle while managing power — ignition timing and the PGM-FI system are adjusted when the rate of change of RPM goes over a set amount. With three settings plus off to choose from, you can have your bike dialed no matter how much traction there is.

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 bike will do the rest, launching you into the first turn with a big advantage.

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.
chassis & suspension

Ride Fast, with Little Fatigue

The CRF450R is focused on being fast while minimizing rider fatigue. They achieved this through optimizing frame rigidity working seamlesly with the suspension to prioritize traction, stability and bump absorption.

Single-pipe Exhaust

The CRF450R uses a single-pipe header. It routes close to the center of the bike, and its light overall construction helps improve weight distribution. The single muffler uses a pressed-alloy design that lets us shape the muffler body for better rider ergonomics and lighter weight.

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.

Rear Suspension

The CRF450R’s frame design lets us fit a special rear shock. The shock’s valving resets fast for better response. In addition, it features a special steel spring that cuts weight without cutting performance.

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.

Hand Guards

When the going gets extra tough, you’ll appreciate the hand guards on the CRF450RL.
