[Digital Today reporter Hong Jin-ju] Kawasaki Heavy Industries has published a patent for a new electric motorcycle design that lets different types of electric motors mount to a single frame.
On March 9 (local time), Electric, an EV-focused outlet, noted that electric motorcycles are typically designed around the powertrain. Motors and batteries often form part of the chassis, and manufacturers build the frame to accommodate a specific motor layout. That approach helps deliver performance and rigidity but reduces flexibility when swapping motors or developing multiple models.
Kawasaki's newly published patent proposes a modular approach to overcome those limits. At its center is a modular mounting system that allows a single main frame to accept various electric motors.
The basic architecture uses a steel trellis frame similar to Kawasaki's Z e-1 and Ninja e-1 electric models. A removable battery pack sits between the frame rails, while the motor is positioned near the swingarm pivot.
The patent's key distinction is that the motor is not bolted directly to the main frame. Instead, the motor and gearbox are mounted to a separate subframe that then attaches to the main frame.
The subframe is divided into upper and lower segments and can be swapped or revised depending on the motor configuration. In practice, different motor units can be installed by replacing only the subframe, without major changes to the main frame.
A modular platform like this could allow multiple electric-motorcycle models to share a common frame, boosting production efficiency and parts commonality. It would also cut development time and reduce costs.
Electric motorcycles have struggled with price competitiveness because batteries and electric powertrains typically cost more than internal-combustion systems. Industry observers say Kawasaki's modular design could help lower production costs and, over time, drive electric-motorcycle prices down.
Kawasaki has not confirmed whether it will apply the design to a production model. Still, analysts see the filing as a move to secure platform flexibility early in electric motorcycle development.
