The EDR Performance R1 Velocity stack kit is finally HERE!  This is for the 2015-2019 R1, R1s & R1m models. Hands down the most PROVEN gains for your R1. No other stack has even come close to our gains! Dyno proven gains of nearly +11 rwhp!  Developed 100% in house on simulation software, then 100% produced in house on our state of the art Mark Forged 3D machines, then put on actual bikes to test fit and confirm, then finally the bikes are placed in our state of the art INC Dyno cell room to test and confirm. Finally they are then finally backed up on the race track with real world data! Our stacks greatly improve torque/HP to smooth power delivery. 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. -EDR R1 Stacks: You can
