2027 Honda® CRF450R Base

2027 Honda® CRF450R

At some point, every great rider discovers that their biggest competition is themselves. And once they do, they do everything they can to make themselves better. It’s the same with our engineers, and our all-new 2027 CRF450R—we took a hard look at our championship-winning 2026 model and made it better in every way. New engine. New frame. Lightest in class with power and torque developed for real race pace, not just dyno sheets. New suspension, and of course a totally new look that you can spot from a hundred feet away. A major makeover that’s nothing less than amazing. And for a select few, check out our CRF450R HRC Works Edition, sharing all the improvements of the CRF450R and more.

Features may include:

• New 450cc Unicam® engine

• Twin-spar aluminum frame

• Showa spring fork

• Hydraulic clutch

• Honda Selectable Torque Control

• 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.

• Sealed airbox and filter

The new airbox design has no separate lid—you can access the air cleaner just by removing the left sidecover.

• 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!

• 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.
