450cc Unicam® engine

Unicam® cylinder-head engine is a hybrid design based on our championship-winning CRF450R. It is lighter, has a lower center of gravity, and a higher compression ratio, all designed to improve the outright power and performance.

Fuel injection

This bike has a proven fuel injection system that offers excellent torque and spot-on metering and response, especially in the critical low-rpm range. It also compensates automatically for elevation and weather changes.

Titanium intake and exhaust valves

Lightweight titanium intake and exhaust valves permit the use of smaller valve springs, reducing overall engine height.

Twin-spar chassis

Excellent handling results from the twin-spar aluminum frame, which is lightweight and rigid. The chassis geometry has been specifically chosen for its responsiveness and is wider than the standard MX frame to accommodate the six-speed transmission.

18-inch rear wheel

The 18-inch rear wheel provides an excellent range of tire options for both on- and off-road use.

IRC GP tires

The tires are designed to provide excellent traction for both on- and off-road use while featuring a long life span.

Low center of gravity

The Unicam® engine, compact in size, and Honda's focus on center-of-mass engineering maintain a low center of gravity. This results in a lighter bike that's easier to handle.

Works-style front brake

Impressive stopping power is the result of a lightweight 260mm front disc and compact twin-piston front brake caliper, while anodized aluminum brake pistons minimize unsprung weight for improved handling and turning.

Works-style rear brake

The HRC works-type rear brake system uses a 240mm brake rotor along with an integrated master cylinder and fluid reservoir. This setup increases durability by eliminating the need for a separate reservoir and hose.

Wide-ratio six-speed transmission

Similar to the 450X, the 450RL features a six-speed wide-ratio gearbox. This allows for the low gear to be excellent in slow, tight situations and a high gear that is tall enough for highway riding to the next trailhead or gas stop.

Electric fan

This bike is designed for all terrains and comes equipped with an electric fan to cool the engine.

Final-drive sprocket damper

Designed to keep your bike quieter while not adding weight, these unique dampened drive sprockets are another example of this bike's innovative engineering.

Inertia-tuned crank

The crank has 13% more inertia than the one used in the 450R, designed to smooth out the power delivery and increase user-friendliness in technical situations.

Lithium-ion battery

The battery is light, compact, and offers excellent performance. This is just another small part of why this bike performs as well as it does.

Skid plate

The factory skid plate is light, yet it also offers the kind of engine and lower-frame protection that serious riders demand on a machine like this.

Titanium fuel tank

The premium titanium tank can hold up to 2.0 gallons of liquid. It is both lightweight and durable.

Works "MX" styling

The "RL" resembles our MX bikes, thanks to their similar smooth bodywork design, making it easy to move around. Additionally, the in-mold graphics not only look cool but are also durable.

Streel-legal and off-road capable

Street-legal in all 50 states, this vehicle is equipped with a catalytic converter and can be ridden off-road almost anywhere. You can ride it on public lands, roads, and in state and national parks. Plus, you won't need to haul your bike to the trailhead.

Factory handguards

Handguards come pre-installed from the factory, fully integrated, and color-matched to the bike. They attach to the control-lever pivots and are vented.

Fuel mileage meter

The fuel mileage meter displays current and average fuel mileage and fuel consumption and can show measurements in miles or kilometers. It's located in the same digital display area as the speedometer.

Gear-driven counterbalancer

The gear-driven counterbalancer serves a dual purpose: it reduces vibration and drives the water pump.

Sidestand

A sidestand may seem like no big thing, but take a look at this one. Tucked up high and out of the way, this forged alloy piece is just another example of how this bike gets it right.

Electric start

An electric start system ensures easy starting in all conditions. The electric starter also drives the clutch side of the crankshaft to provide superior lubrication to the starter gears while producing a narrow engine with a short, strong crank.

LED headlight

This bike has all-LED lighting, including the headlight, which reduces weight on the front end. The lighting pattern is designed for on- and off-road situations.

LED taillight

The rear fender of the vehicle includes an integrated LED taillight that is designed to be light, compact, and rigid.
