You don’t need a PhD in physics to know that adding power to a vehicle will usually make it accelerate faster and give it a higher top speed. Reducing weight will improve acceleration, as well as braking and cornering ability. Do both to the same vehicle and you see a substantial increase in performance. Keep in mind this is as true with two-wheeled machines as it is with four-wheelers.
