Which type of motorcycle features rear-positioned footrests, high power-to-weight ratio, and a forward leaning ride?

Answer: D — Sport

Sport motorcycles have rear-positioned footrests, high power-to-weight ratio, and a forward leaning ride, making them the best option out of the given choices. Cruiser motorcycles have more relaxed seating positions, while standard and touring motorcycles have rear-positioned footpegs but are heavier and do not have as much power as sport motorcycles. Therefore, D is the best answer.
