Tuning Tips:
Light rollers are good for quick acceleration, stop and go riding and hills, but you loose top end speed.

Heavy rollers will give you a higher top end speed (long roads) but you will loose low end acceleration.

If you’re a heavy person (and/or) if you have a stock motor you will want to lean towards the lighter rollers. If you are a light person (under 140lbs) or you have a big bore you will want heavier rollers.
