From a press release issued By Honda:

By its very nature, dual-sport riding demands many things from a motorcycle, a fact that presents challenges for engineers. That's what makes Honda's adaptable CRF450RL so amazing: based on the legendary CRF450 Performance platform, it has a 449cc Unicam® engine, twin-spar aluminum frame and premium, long-travel suspension that make it a stellar performer off-road. At the same time, it's surprisingly smooth and comfortable when linking those experiences via pavement, thanks to a quiet muffler, a vibration-damping urethane-injected swingarm and a wide-ratio six-speed transmission. Throw in Honda's legendary durability, and it's no wonder this road-legal dirt bike has made a name for itself in the dual-sport world.

KEY FEATURES

- Lightweight, protective hand guards defend against the elements and trail-side shrubbery
- Lightweight, 2.0-gallon titanium fuel tank
- Riding time maximized by lightweight, compact LED lighting system, featuring a headlight with high-intensity projection for illuminating a broad area
- Rear-view mirrors
- Lightweight lithium-ion battery with increased capacity compared to CRF450R, to power electrical components
- Lightweight, compact digital meter with black characters on a white liquid-crystal background is easily legible while riding

ENGINE / DRIVETRAIN

- 449.7cc Unicam® engine specially tailored for trail-to-trail riding
- Finger rocker arm contributes to compact layout while using dedicated design to attain on- and off-road-specific power characteristics. DLC surface treatment reduces friction
- Dedicated valve timing for smooth power delivery in technical riding
- High crank inertia (up 12% over CRF450R) for tractable power delivery in technical terrain
- 12.0:1 compression ratio
- New piston with three-ring design
- Wide-ratio six-speed transmission is ready for a wide variety of off-road terrain and on-road riding
- Special clutch design enables light lever pull. Primary damper mechanism with friction springs suppresses engine torque fluctuations, ensuring smooth running
- Large-capacity radiators with high heat-exchange efficiency for strong performance in demanding off-road conditions
- Electric fan and thermostat control engine temperature in harsh conditions
- ECU with dedicated settings
- Noise emissions minimized via covers on the left and right crank cases
- Powerful AC generator for street-legal lighting
- Air cleaner box
- Dedicated single-muffler exhaust system provides great sound while meeting emissions requirements

CHASSIS / SUSPENSION

- Aluminum twin-spar frame designed for nimble-yet-stable handling on trails
- Subframe designed to ensure optimum rigidity balance appropriate for carrying tools
- 49 mm Showa fork with dedicated settings for trail-to-trail riding
- Shock based on that of the CRF450R but with dedicated settings and link ratio for off-road riding
- Front brake uses design from CRF450R, but with additional fade resistance thanks to thicker discs and large-capacity reservoir
- Endless sealed chain withstands the elements
- Front and rear sprockets, produced in durable steel material, feature damper system for smooth, quiet running
- Urethane injection in swingarm to reduce road noise
- Fuel tank cap with a cut-off valve prevents fuel from flowing out of tank if the bike is on its side
- LED turn signals with flexible mounts for durability
- Easily accessible electronic component box on left side of the frame
- Black 7/8" Renthal handlebar with red pad
- Compact, lightweight handlebar switches
- In-mold graphics are resistant to peeling caused by washing or abrasion
- IRC GP-21F/GP-22R tires provide great balance of on- and off-road performance
