Significance of max torque and power ?. Review on Hero Honda Glamour

I want to know the impact of max torque and power value with respect to RPM of engine.( I want to take 125CC bike so selected those only)

COnsider :

Glamour :

Maximum Power: 9. Bhp @ 7000 rpm

Maximum Torque: 10.35 Nm @ 4000 rpm

Shine:

Maximum Power: 10.3 Bhp @ 7500 rpm

Maximum Torque: 10.9 Nm @ 5500 rpm

Galidiator:

Maximum Torque: 10.4nm@6500rpm

Advantages and disadvantages having max torque and power at low or high speeds by comparing similar bike. Please spare your valuable time and update me.

My Observation : Engine having max torque at low RPM means high torque at low speeds .. leads to less gear changes. Benfit in city riding. Whether this will leads to vibration, less mileage ?? ( I dont know... just want to know thats why posted this).

I know I am posting in a wrong category .. I dont think mouthshut has general category .. thats why posting my general question....Please spare your time and update me.

Advance Thank You ...
