Question

I can roughly feel a force of 10 newton only by considering the weight of 1 kilogram object.

How to imagine the following measurements?

Maximum horsepower 16 hp @ 9,500 RPM

Maximum torque 12.76 N

Answer 1

16 horsepower is too high to be easily compared to everyday life. If you take one horsepower instead, then one horsepower is about 740 J/sec. For an average male of 75kg, this is the power required to lift you at 1 m/s. So suppose you were climbing a ladder, then 1 horsepower requires you to climb the ladder at 1 m/s. I suspect most of us could only manage a fraction of this!

The torque is more easy to imagine. A typical childs seesaw is about 2m long i.e. about 1m from the pivot to the end. If you placed a 1.276 kg weight on the end of the seesaw than 12.76Nm torque is what you'd feel at the other end when you press on the seesaw to keep it level.

The torque sounds tiny, but remember that's the torque at the motor not at the wheels. At the typical maximum speed of a small motorcycle the engine is turning about 15 times faster than the wheels, so the torque at the wheel is about 15 times as large i.e. 191Nm. That's like putting 19kg on the end of the seesaw.
