EDR Performance Aprilia RS660 Velocity Stacks

EDR Performance RS660 Velocity Stack kit 

The EDR Performance RS660/Tuono 660 2021+ Velocity stacks are the PROVEN best for your Aprilia, we spent hours on the dyno comparing the competitions and ours and didn't settle until we beat them all!

Dyno proven gains of 5-8 rwhp is no joke on these bikes! (Tuono owners with our ecu can see over 15rwhp!)  Developed 100% in house on simulation software, then again, 100% produced in house on 1 of our 2 state of the art Mark Forged 3D machines, then put on bikes in our state of the art INC Dyno cell room to test and confirm, then finally backed up on the race track with real world data!

Our stacks are ran in numerous club racing organizations around the world as well as many top MotoAmerica teams (we cant say who due to contracts)  Our 660 stacks greatly improve torque/HP to smooth power delivery. The stock stacks cause the bikes power to greatly fall off around 9,500 rpm however our 660 stacks will keep your great stock like power band and torque but allow it to breathe all the way past 11,500 rpm! 

EDR Performance velocity stacks provide a smooth power while allowing the bike to continue making power all the way to redline. This allows the rider a true feel for the throttle giving a more accurate throttle inputs, improves confidence to get on the throttle sooner and boosts rider confidence.

*stacks are not available in colors, only black due to the proprietary Onyx + Carbon Fiber filament. This material is very high end, with a 145*c+ temperature stability rating and is unaffected by race fuel, they will most likely out live your motorcycle! 

These kits do not contain instructions, however you simply remove your oem ones and bolt our 660 stacks in, very simple! These are intended for racing use off road use only.
