Sure, but yamaha still makes that power after 12 months
Perhaps I didn't understand that short sentence
Torque is not power. Any transmission system acts as either divider or multiplier of torque to the drive-wheel, and torque translates to force exerted on the ground to make a vehicle move.
In a car, the gearbox (and the rest of the transmission) typically reduces the rpm of the engine but multiplies torque at driven wheels. The lower the gear, the higher the effective torque. It makes the car accelerate fast from the lowest gears. There are situations when too high torque has adverse effects, such as starting the car from ice, snow, mud or sandy surface because the driven wheels may slip and the car wouldn't move. A manual gearbox driver would upshift to gear #2 to reduce excessive torque in the wheels.
Once the car got on the speed, it is in the high gear and the torque at wheels is low. It is hard to accelerate at the high gear.
In bikes (and e-bikes), the drive-train acts either as torque multiplier (in low gears) or divider (in high gears). Again, a climbing cyclist in their granny gear delivers the most of the torque to the rear wheel at the cost of low speed. On contrary, a road racer is at high gear, delivering the least torque to his wheel (that's why Specialized 1.1 motor of Turbo Creo SL only delivers 35 Nm). It might happen that a mountain cyclist delivers too much of torque on climbing. If that's a wet slab, mud, etc, the wheel might slip because of excessive torque.
For the rest of us, the motor torque only translates to the acceleration ability. High torque, and you are at speed in seconds after you started from the green signal. Low torque (hub motors) and it is painful to cross a junction from a cold start. Once a good speed has been reached, the torque is meaningless.
Of two similarly built e-bikes, the faster one will be that with higher maximum power. If one motor can deliver 250 W and the other 500 W, the latter will be faster if unrestricted.

I write all of this because the OP doesn't seem to understand the basic rules of the mechanics.
