CRF450R Features
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 2025 model 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 has been refined to allow a 13.5:1 compression ratio for superior power and efficiency, with a generous squish area.
Double-spray injector settings
The system sprays fuel twice per intake cycle for better atomization and increased power in the midrange and on overrev. You'll feel it during your first race.
Single-pipe exhaust
The single-pipe header routes close to the center of the bike, and its light overall construction helps improve weight distribution. A new design for 2025 helps produce more controllable power in the low—and mid-rpm range.
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.
New frame
A superior frame is crucial for great handling. The chassis weighs 1.5 lbs less than the previous generation's due to the narrow main spars. Almost 70 percent of the frame components are new this year, resulting in excellent turning performance and better compatibility with the new suspension.
New tripleclamps, axle, and steering stem
New 2025 triple clamps work with the updated frame, fork, axle, and steering stem for consistent suspension and improved rigidity, responsiveness, and turning.
Showa spring fork
The 49mm Showa fork features a design that helps increase the front suspension's precision and feel, while the new springs, new seals, and new valving for 2025 improve the consistency of the stroke feel throughout the entire range of travel.
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. The brake disc guards are included on both the front and rear discs.
Dunlop MX33 tires
MX racers prefer Dunlop tires for superior performance in diverse conditions, improving cornering grip.
Hydraulic clutch
Inspired by our Grand Prix MX machines, Honda's first hydraulically actuated dirt bike clutch offers a 10% lighter clutch lever pull. It eliminates the need for cable adjustments, delivering optimal performance on even the longest motos.
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 handlebar-mounted button, activating our Honda Selectable Torque Control (HSTC) system that offers three customizable settings to optimize your ride based on available traction conditions.
Titanium fuel tank
These bikes feature a lightweight titanium fuel tank that maintains the same capacity as its plastic predecessor while maximizing space and centralizing the fuel 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.
Slim bodywork
Slim bodywork gives the bike more freedom, while reduced fasteners allow for easier off-bike maintenance.
Exclusive works edition
The CRF450RWE Works Edition includes all CRF450R features and more. It has a hand-ported cylinder head, Hinson clutch basket, Twin Air filter, Throttle Jockey graphics, upgraded DID DirtStar LT-X rims, an exclusive Yoshimura exhaust system, Kashima and titanium oxide-coated lower fork legs, revalved suspension, an RK gold chain, special ECU settings, and black triple clamps.
Fresh styling
The 2025 bikes get new “stacked” CRF graphics that take their styling cues right from our HRC works bikes. Plus, our “in mold” graphics are more durable, keeping them looking good, especially after repeated track sessions and cleaning.
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.
Renthal "Fatbar"
The Renthal Fatbar, made from aluminum, has a bend superior to the Honda “CR” bar, making it the new standard in excellence. You will love it!
Black rims
Lightweight and strong, the black DID DirtStar rims add a stylish touch, too.
Electric starter
Our engineers made the bike lighter by using an electric starter and lithium-ion battery.
Switch assembly
We've made the controls easy to use with features like launch assist and selectable power modes so you can focus on winning.
Engine mode selection button
Customize your engine's power delivery on the fly with the convenient handlebar-mounted button, allowing you to effortlessly switch between Standard, Smooth, and Aggressive modes to suit varying track conditions.
HRC launch control
Get a competitive edge with this bike's unique ECU program. Select the mode, open the throttle, and release the clutch to dominate from the start with its holeshot-seeking design.
