- Uses radar-based rider and semi-auto gearbox
- Based of the Y-AMT tech currently available
- Could be introduced by 2027
Yamaha has filed a new patent that offers a glimpse into how future motorcycles could become even more intelligent, with advanced integration between radar-based rider aids and semi-automatic transmission systems.
The patent outlines a technology that would allow a motorcycle to automatically downshift while slowing down under adaptive cruise control, combining traditional braking with engine braking to deliver smoother and more controlled deceleration.
Rather than relying solely on the braking system, the proposed setup is designed to manage multiple vehicle functions simultaneously. According to the patent documents, the motorcycle would initially reduce throttle input before automatically selecting lower gears to increase engine braking. Only after those measures have been applied would additional brake pressure be introduced if further deceleration is required.
The result is a more natural slowing process that mirrors the techniques used by experienced riders. In normal riding conditions, skilled motorcyclists typically roll off the throttle, progressively apply the brakes and downshift through the gearbox to maintain stability and control while reducing speed. Yamaha’s patented system aims to replicate that process electronically.
The technology appears to build upon systems already found in motorcycles such as the Yamaha Tracer 9 GT+ Y-AMT, which combines radar-assisted adaptive cruise control with the company’s automated manual transmission technology. However, the newly filed patent suggests a deeper level of integration, where braking, gear selection and even suspension behaviour could work together as part of a single coordinated rider-assistance package.
A key element of the concept is the use of a semi-automatic transmission. Because the system would need to execute gear changes independently during braking events, conventional manual gearboxes would not be capable of supporting the functionality without rider input.
If developed for production, the technology would likely debut on Yamaha’s premium touring and sport-touring motorcycles before filtering down to other segments. As with all patent applications, however, there is no guarantee the system will reach production. Motorcycle manufacturers frequently file patents to protect potential technologies, many of which never progress beyond the development stage. Even so, the filing provides a strong indication of Yamaha’s direction of travel, suggesting future motorcycles could feature even closer integration between radar systems, automated transmissions and chassis electronics to create a more seamless and intuitive riding experience.
