EDR Performance Yamaha R6 2008-2025 Velocity Stacks
The EDR Performance R6 Velocity stack kit for the 2008-2025 models are the PROVEN best for your R6. No other stack has even come close to our gains!
Dyno proven gains of nearly16 rwhp! Our stacks EMABARASS the others including GYT-R YEC stacks!
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 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 is excited to be the ONLY manufacture to offer TWO designs to custom tailor your bikes power band exactly as you need. So if you are a street rider, track day enthusiast, roll racer, drag racer or just someone that wants the most out of their R6, our velocity stack kit is hands down the best gain per $$ you will ever get!
-Stage 1 "Standard" is our proven velocity stack design with hundreds sold and used around the world! This version gives the smoothest power band you can get over any other velocity stack and we see gains of up to 10 rwhp while seeing NO loss of power and torque in the entire power band. Best all around use, street, tight tracks
-Stage 2 "Hi Rev" is our latest upper stack design. While our Stage 1 velocity stacks have been proven around the world in dyno shoot outs, road racing, street bike riding and track days, we wanted to create a design that would produce even more top end and top speed! These stacks provide near stock power levels from idle to 11,000 rpm but REALLY come on from 11,000-17,000!
We get OVER 16+ rwhp at 14,800 rpm. This is perfect for the R6 owner wanting maximum top end power, especially great for long road courses (Think PIR, Road America, Thunderhill, etc) or drag racing. These have been shown to produce OVER 15 rwhp on our EDR R636cc superbike engines!
See the attached dyno charts to help you decide on what Stage works best for you or get BOTH and have both options!
