A New Challenge in Electric Technology (1)

To experience joy with your whole being.
And to become one with nature, friends, society, and your machine
as you unleash your instincts and let your heart soar.

We at Yamaha Motor believe this is the Kando we should give to riders.

No matter how much the powertrain develops or advances,
its essence remains unchanged.

The smile that glows when the helmet comes off.
We hope to keep delivering those smiles as we respond
to society’s demands and expectations for mobility.

Yamaha Motor is making inroads into EV.
The first step in this approach is the Series Parallel Hybrid
designed for use in mid-size scooters.

SPHEV^* system

The SPHEV system consists of two motors and an engine. The first is a drive motor for propulsion. The second is a generator motor connected to the engine. The engine not only generates power but can also be used to drive the vehicle.

Battery drive mode

When used in the mode that automatically switches the drive, it first runs as an EV using only the drive motor. As it decelerates, the regenerative brake charges the battery.

Series hybrid drive mode / Engine drive mode

After starting to drive, the engine will start and generate power according to the battery level.
At medium and high speeds, the power source switches from the motor to the more efficient engine.

Dual Boost mode / Triple Boost mode

When the accelerator is engaged, motor drive is added for greater power when riding. When greater acceleration is needed, the generator motor contributes to driving power, giving a triple-boost.

The SPHEV system under research and development can be installed in a vehicle with a vehicle size equivalent to that of a conventional engine-only motorcycle. It offers wide-ranging performance in a compact size, providing a powertrain with boundless freedom.
