The details behind the dominance
Join Justin Brayton and Honda HRC Progressive factory riders Jett and Hunter Lawrence for a closer look at how the all-new CRF450R raises the bar in race-ready motocross performance.
Five decades of being the best
New 450cc Unicam® engine
A new engine this year features a new Unicam valve layout that aligns intake and exhaust rockers on a common axis to increase valvetrain rigidity while also resulting in a more compact package.
New frame
The 2027 frame may look the same, but it’s really all new, with slightly more steering rake and a longer wheelbase. The major frame components have been fine-tuned for rigidity and weight loss. Meanwhile, the footpegs moved back 5mm, making it easier to shift your weight over the rear wheel to help it hook up.
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.
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.
Because fractions of a second matter
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.
Larger intake and exhaust valves
The titanium intake valves have increased in diameter from 38mm to 40mm, and the exhaust valves from 31mm to 32mm. The valve angle in the head also changed (included angle remains the same), to optimize intake efficiency. The intake port is shorter too, all contributing to the boost in power.
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.
Showa® spring fork
A 49mm Showa® fork features Kashima coating to the internal sliding components, enhancing stroke feel and improving smoothness. A DBS (Dynamic Blow System) main-piston valve increases compression damping in the extremely low-to-low speed range, improving stroke consistency.
Rear suspension
A lighter shock body is surrounded by a new red spring. The shock itself is more responsive, enhancing damping feel in the low-speed compression range and providing a more consistent feel throughout the suspension stroke.
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.
Bold Honda graphics
There’s no way you can miss the new Honda graphics on our 2027 CRF450R. Straight off our factory MXGP bikes, everyone will immediately know you’re on a 2027 model. The blue rear fender and side number plates are a nice nod to Honda’s dominant historic motocross bikes, too.
Black rims
The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.
Superior frame rigidity
Great handling starts with a superior frame. First, it’s light. By making the frame’s main spars narrow, we save weight, but more importantly we make the chassis more responsive by fine-tuning the lateral rigidity. The result is a bike that gets into, around, and out of corners faster.
