Ok that headlines is a slight exaggeration on the truth, as Yamaha Motor is actually offering a range of prototype motors that produce 35kW to 200kW of power, which works out to be a range of 47hp to 268hp. Still, that is a lot of juice.

The prototypes are a range of interior permanent magnet synchronous motors (IPMSM), which are scalable in design and suitable for a variety of uses.

While the video of MotoCzysz putting their new D1-10 electric motor up on the dyno is not terribly captivating (it’s hard to see anything really moving since all the fun bits are inside the motor’s casings), the performance figures the company quotes surely are impressive. The liquid-cooled IPM motor makes 250lbs•ft of torque, generates over 100hp, and employs a proprietary cooling system to allow a higher percentage of that peak power to be used over extended periods of time. This is particularly important because of the large gap between peak power figures and sustainable power figures in the electric motorcycle world, with the latter being the more important figure to quote.
