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. Specifications Size: 16×13 Available Weights: 5.0, 6.0, 7.0, 8.0s, 9.0, 10, 11, 12 grams.
