Comfort & Convenience

• DETAILED BODYWORK MOUNTING: It may seem small, but every second counts when you’re servicing your bike between motos. Fewer mounting bolts mean enhanced serviceability at the track or in your garage.
• ELECTRIC STARTER: To keep the bike light, our engineers use an electric starter with a lithium-ion battery.

Engineering

• HYDRAULIC CLUTCH: Inspired by our Grand Prix MX machines, the hydraulically actuated clutch offers a 10% lighter clutch lever pull compared to a cable equivalent. It also eliminates the need for adjustments, delivering optimal performance for even the longest motos.
• HIGH-CAPACITY RADIATOR: A six-percent larger radiator compared to the previous generation provides the cooling capacity needed to sustain the engine's high power output.
• GEAR-POSITION ENGINE MAPPING: The smart ECU delivers tailored engine mapping for each gear, giving riders the edge with optimal power for every track, turn, jump, and rut.
• EIGHT-PLATE CLUTCH ASSEMBLY: The eight-plate clutch design delivers 85% less slip at peak horsepower and 27% more torque transmission than a seven-plate clutch. Due to the hydraulic actuation and super-strong spring lockup, it maintains a light clutch-lever pull.
• HONDA SELECTABLE TORQUE CONTROL (HSTC): Easily control your bike's traction with the left-side handlebar-mounted green button, activating our Honda Selectable Torque Control (HSTC) system. It offers three customizable settings to optimize your ride based on conditions or preference.
• TITANIUM FUEL TANK: Every gram counts, so we gave the bike a titanium fuel tank. Light and strong, it’s also thinner than our previous plastic unit, freeing up more space and helping to centralize the fuel’s mass.
• ONE-PIECE RADIATOR SHROUDS: Our engineers used Computational Fluid Dynamics to fine-tune the radiator shrouds for increased cooling efficiency. The one-piece design ensures consistent power output and prevents overheating.

Handling

• RESPONSIVE FRAME: A superior frame is crucial for excellent handling, and the chassis delivers. It's lightweight and responsive, with narrow main spars, and was designed with direct input from Team Honda HRC riders.
• TRIPLECLAMPS, AXLE, AND STEERING STEM: Compared to the previous generation, we revised the tripleclamps, frame, fork, and steering stem for improved chassis rigidity and responsiveness to give the bike better cornering feel.
• SHOWA® SPRING FORK: A 49mm Showa® fork with a conventional spring, 39mm piston diameter, and 25mm rod diameter is designed to have a supple feel that still resists bottoming under heavy loads like big jumps, bumps, or ruts.
• REAR SUSPENSION: A specially optimized rear shock has been tailored to the frame, complemented by a lightweight steel spring that maintains exceptional performance.
• LIGHT NARROW FRAME: Experience faster cornering with the lightweight, superior chassis design, which maintains finely tuned lateral rigidity.
• NARROW SWINGARM: Our swingarm design matches the chassis' lateral rigidity for balanced frame stiffness. This allows for faster cornering and a better feel.
• LIGHTWEIGHT SUBFRAME: The subframe is nearly three-quarters of a pound lighter than the last generation’s part. We’ve simplified its construction too.
• REAR BRAKE PADS: Brakes do more than stop the bike. They help set up turns and jumps. Our brake pads last longer and provide more stopping power to help you win.
• 260MM FRONT BRAKE: The front brake disc measures 260mm, providing excellent brake feel and weight reduction. We’ve also included a guard to protect against roost and rocks.
• DUNLOP MX33 TIRES: Dunlop’s MX33 tires feature an intermediate design that works well in a wide variety of conditions, providing superior rider feedback and improved cornering grip.
• RENTHAL FATBAR: Renthal’s aluminum Fatbar comes standard, featuring a bend superior to the Honda CR-bar, making it the new benchmark in excellence. You will love it!

Performance

• 450CC UNICAM® ENGINE: The Unicam® cylinder head offers a compact, lightweight design with a narrow valve angle, which improves combustion chamber efficiency, increases compression ratio, and lowers the center of gravity.
• SEALED AIRBOX AND FILTER: We've maximized torque output with a unique airbox shape and filter design. The filter is easily accessible and features a gasket-less design for quicker and easier cleaning and servicing.
• CENTRAL-PORT CYLINDER HEAD: The engine features an oval-shaped centralized exhaust port, which, along with the single-muffler exhaust, boosts power from 5000 rpm up and increases exhaust efficiency.
• TITANIUM INTAKE VALVES: Lightweight titanium intake valves reduce reciprocating mass and permit the use of smaller valve springs, reducing overall engine height.
• FUEL INJECTION SYSTEM: Meticulous details like the 60-degree angled fuel injector put this bike ahead of the competition. It delivers a cooler and denser fuel charge, increasing power and torque.
• 13.5:1 COMPRESSION RATIO: The combustion-chamber shape allows for a 13.5:1 compression ratio, producing superior power and efficiency, with a generous squish area.
• 13.5:1 COMPRESSION RATIO: The combustion-chamber shape allows for a 13.5:1 compression ratio, producing superior power and efficiency, with a generous squish area.
• SINGLE-PIPE EXHAUST: The single-pipe header routes close to the center of the bike, and its light overall construction helps improve weight distribution. It also produces more controllable power in the low- and mid-rpm range than the previous generation.
• YOSHIMURA EXHAUST: The CRF450RWE’s exhaust is another premium item. It uses a stainless header with a titanium mid-pipe and muffler made especially for us by Yoshimura. Super light and super trick, the exhaust tucks away for better ergonomics, too.
• EXCLUSIVE WORKS EDITION: The CRF450RWE Works Edition gets a hand-ported red cylinder head, Hinson clutch basket and cover, Twin Air filter, gripper seat cover, DID DirtStar LT-X rims, Yoshimura exhaust system, Kashima-coated fork legs, revalved suspension, an RK gold chain, special ECU settings, and black triple clamps.

Style

• SLIM BODYWORK: Slim bodywork gives the bike more freedom, while reduced fasteners allow for easier off-bike maintenance.
• STACKED CRF LOGO: Like our factory racebikes, our CRF competition lineup features the vertically stacked CRF logos that look fast even sitting still.
• HRC THROTTLE JOCKEY GRAPHICS: The CRF450RWE gets an exclusive Throttle Jockey graphics package inspired by our HRC works bikes, while the durable "in mold" graphics ensure long-lasting visual appeal even after intense track sessions and repeated cleaning.
• BLACK RIMS: The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.

Technology

• ENGINE MODE SELECTION BUTTON: Customize your engine's power delivery on the fly with the convenient left-side handlebar-mounted blue button, allowing you to easily switch between Standard, Smooth, and Aggressive modes to suit varying track conditions or rider preference.
• HRC LAUNCH CONTROL: This special ECU program allows you to select a start mode, then simply hold the throttle open and release the clutch, letting the bike do the rest. Trust us when we say it turns it into a holeshot-seeking machine!
