Pro-grade performance
Exclusive HRC Works Edition
The CRF450R HRC Works Edition gets a hand-ported cylinder head, red cam cover, Twin Air filter, gripper seat cover, DID DirtStar LT-X rims, Yoshimura exhaust system, Kashima-coated fork legs, revalved suspension, a D.I.D DM2 gold chain, special ECU settings, and black triple clamps.
Yoshimura exhaust
The CRF450R HRC Works Edition’s exhaust is another premium item. It uses a new titanium header, mid-pipe and muffler made especially for us by Yoshimura. Super light and super trick—the exhaust tucks away for better ergonomics, too.
HRC-inspired graphics
The CRF450R HRC Works Edition gets hand-polished cylinder ports with a red metallic cylinder head cover, Twin Air filter, gripper seat cover, DID DirtStar LT-X rims, Yoshimura exhaust system, Kashima-coated fork legs, revalved suspension, a DID DM2 gold chain, special ECU settings, and black triple clamps.
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.
Factory-level finish
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.
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.
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.
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.
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.
