Yamaha Patents Electric Motors With Fake Machines To Present Exhaust Sounds

JAKARTA - All electric vehicles, both cars and motorbikes, are synonymous with silence and subtleties that sometimes for some people eliminate the sensation of driving. To overcome this problem, a number of electric vehicle manufacturers are planning to vote on their products.

Now, the two-wheeled giant Yamaha also has a unique solution by installing conventional machines that don't work, purely just to produce exhaust sound and vibrations. This is done because many real riders miss the roar, vibration, and roar of hard machines, something electric motors that are quiet and smooth.

Reporting from Visordown, Tuesday, September 30, the Japanese manufacturer recently filed a very unique patent for their electric motor, where the point is to make electric motors feel like gasoline motors.

According to the patent document submitted to the World Intellectual Property Organization (WO/2025/191637), the electric motor Yamaha developed will be equipped with so-called conventional machines, but functionally non-existent.

This scheme shows that the main driving force (which gives power to the wheels) will rotate an engkol (crankshaft) axis that runs a four-ton mini engine.

All these mechanical processes occur without using fossil fuels. The only goal of this small machine is to mimic the sound, vibration, and heart rate of a gasoline machine that has been known for more than a century.

Sensation Connected To Speed

In a patent translation from Japanese, it is stated that air pressure fluctuations due to the back and forth movement of the piston will create compression waves in the intake pipe, exhaust pipe, and resonator. This resonator is in charge of strengthening the sound.

"This allows motorcyclists who drive wheels to produce intake and exhaust sound similar to back and forth," explained the patent document.

In other words, the sound and the resulting vibrations should be direct correlated with the way motorists operate electric motor gas. The more aggressive you drive, the harder you get and the "live" of the sound that is issued.

The design of this motorbike will also resemble conventional motorbikes, so that visually, audially, and taktilly, motorists will feel like riding an ICE motorbike, even though it is electric.

This Yamaha move is considered a clever innovation, but also raises a big question: Is this really what the market wants?
