i can get on board with what jwm is saying. its great having more power, but if you cant control it then whats the point? suspension (and tires) will help you be able to use more of the available power more frequently.
you could take 2 identical bikes and put proper suspension on one and go significantly faster on that bike.
if all youre looking for is straight line top speed highway runs with your buddies, then just the bottle to it and be done.
