Electrification and digitalization are redefining the two-wheel and small urban vehicle sectors. At the Japan Mobility Show 2025, Yamaha unveiled a series of concepts that look not only at new energy solutions, but also at the relationship between human and machine, the riding experience, and the intelligent use of emerging technologies
When discussing mobility today, attention is most often focused on sustainability and the evolution of propulsion systems—two goals that are driving major transformations across all transport sectors through the emergence of new solutions. Examples include vehicles designed for micromobility or drones that will soon support short-range urban air mobility. Within this context, digitalization and the integration of artificial intelligence also play a key role, with AI poised in the near future to radically transform human–machine interaction by replacing the current concept of a piloted vehicle with that of an autonomous one.
We are therefore living in a historical moment in which multiple evolutionary forces converge—forces that Yamaha sought to materialize in functional prototypes displayed to the public at the Japan Mobility Show 2025 in Tokyo. Taken together, these vehicles propose alternative and complementary paths aimed at redefining individual and urban mobility.
The most futuristic concept developed by Yamaha is MotoroiD:Λ, originally conceived in 2017 as a hypothesis of an autonomous motorcycle capable of maintaining its own vertical stability and interacting with the rider. The 2025 version introduces new AI-based technologies that qualify the prototype more as an autonomous drone than as a rider-controlled vehicle. Its management system operates on reinforcement-learning algorithms trained in virtual Sim2Real environments and then applied to the real world, enabling the machine to continuously expand its functional capabilities as it is used.
The vehicle’s structure features a lightweight yet robust composite-material exoskeleton, designed to withstand the trial-and-error inherent in the learning process. Articulated joints paired with electric actuators allow the machine to implement active geometric reconfiguration strategies of its structural components. This is made possible by dedicated electric motors for each wheel and a wide range of inertial and telemetry sensors. The vehicle can therefore lift itself autonomously and maintain balance while simultaneously adapting to user-defined objectives.
With MotoroiD:Λ, Yamaha raises fundamental questions about the boundary between rider and machine. The presence of an artificial intelligence that learns, evolves, and makes decisions introduces ethical questions regarding the degree of autonomy entrusted to the vehicle, responsibility for actions, and the nature of “complicity” between human and machine. This is a form of mobility that does not merely assist, but potentially co-drives, transforming the rider’s role from controller to co-evolver.
The second prototype presented is Tricera Proto, a three-wheeled, open-top vehicle designed to offer an innovative driving experience through a new three-wheel steering (3WS) system. It delivers improved performance during direction changes by altering the sensations perceived by the driver compared to a traditional vehicle. The steering control system was developed based on human-factor research into dynamics and driver feedback, with the aim of creating a deeper rider–machine bond. Meanwhile, the arched central frame forms a balanced “three-wheel” structure, harmonizing “human spaces” with “functional spaces.”
The concept also explores the human–machine interface from an acoustic perspective, pairing its electric propulsion system with an audio setup called αlive AD Sound Control, which modulates, enhances, or counteracts mechanical sounds depending on the vehicle’s operating state to emotionally engage the driver. Propulsion is provided by a battery pack feeding high-performance electric motors with individual wheel control, while the body arch is constructed from lightweight composite materials.
While electrification remains one of the central themes in the development of new vehicle generations—also underscored by the launch of the Proto BEV, a supersport evolution of Yamaha’s electrified concepts—it is equally interesting to note Yamaha’s exploration of alternative propulsion solutions for scooters and micromobility based on hydrogen-fueled internal combustion engines. In this context, Yamaha presented the H2 Buddy Porter Concept, a scooter developed in collaboration with Toyota Motor Corporation, which supplied a compact, high-pressure tank certified for motorcycle use.
The vehicle is capable of covering over 100 kilometers on a single fill, complies with Euro 5 standards, and features significant limitations on nitrogen oxide emissions. It is noteworthy that Yamaha is exploring hydrogen propulsion precisely in the scooter segment, where battery-electric mobility arguably makes the most practical sense. This is a technically bold choice, but one that brings with it significant challenges: the bulk of high-pressure tanks, hydrogen refueling logistics, material structures, and costs. Especially considering that a 100-kilometer range is already achievable today with electric scooters requiring lower investment and simpler infrastructure.
That said, the prototypes presented by Yamaha are neither previews of future production models nor mere exercises in design or engineering. Rather, they represent conceptual theses aimed at exploring new development trends at a time characterized by high technological uncertainty and an increasingly profound transformation of the human–machine relationship.
