$ 199.00
Title

Dyno-proven gains don't lie! Developed in house on simulation software & then backed by dyno testing SAME DAY back to back with real work data. Our stacks improve torque/HP to increase power delivery. Our stacks provide a smooth throttle always. This allows the rider a true feel for the throttle giving more accurate throttle inputs, improves confidence to get on the throttle sooner, and boosts rider confidence. We have seen gains if 5-8hp depending on your RS660 mods & tuning! We have focused on getting the bike to remain strong and accelerating all the way to redline as the stock stacks fall off drastically above 9500rpm. Our stacks make power everywhere but really shine 9,500-11,500+ right where Aprilia RS660 owners have asked!

The production stacks are produced with the highest quality Onyx + Carbon Fiber reinforcement. These stacks are for race use, off-road competition use only. Not road legal!
