I love three aspects of the 08 Ailerons. First is the decent amount of rubber to damp vibration. This is followed by the thumb notch near the bar, I find it a perfect size for my hand. Lastly is the wing in front. All it takes is a little drag up on it with gloves and you can hang your hand in a completely relaxed positing and still maintain throttle. I've put them on three out of four motorcycles I've owned and wish I would have done it on four.
