AMONG SUZUKI ACCEESS AND HONDA ACTIVA WHICH ONE IS BETTER REGARDING MAINTENANCE, BRAKE EFFICIENCY AND HASSLE FREE SELF STARTING

How can a 1000cc engine from a motorbike produce 185hp, but the average 2000cc engine from a car only produce between 130-150hp? seems silly to me! Why not take the 2000cc engine out of the car and replace it with an engine from a kawasaki ninja? surely the this would make all of our cars much more economical and improve performance!
