Meanwhile, the CBR400R FOUR E-Clutch Concept is built around the theme “New Generation Sport – Everyday exhilaration.” The full-fairing sportbike focuses on enhancing the emotional connection between rider and machine, especially in moments where riding enjoyment takes center stage.

Its design features sharp, sculpted surfaces inspired by machined metal, paired with a futuristic lighting signature that emphasizes its advanced and performance-oriented character.

New platform, new engine, and advanced riding technologies

Both concept models are based on an all-new platform, incorporating a newly developed chassis and suspension setup engineered to maximise riding enjoyment.

At the heart of these machines is a new inline-four engine, paired with Honda’s latest electronic innovations. Key highlights include Honda’s E-Clutch system, enabling automatic clutch control for smoother and more accessible riding, and also Throttle-by-Wire which helps to deliver precise and responsive throttle input

Together, these technologies aim to enhance control, comfort, and overall riding dynamics, making the bikes more engaging for both new and experienced riders.
