Our Velocity are game-changers.
Dyno-proven gains don't lie! Nearly 10% at the rear wheel! That is huge on these little guys!
Developed in house on simulation software, the race track and then backed by dyno testing with real work data. Our stacks improve torque/HP to smooth power delivery. Our stacks provide a smooth power. 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 overall rideability.
The production stacks are produced with the highest quality material. These stacks are for race use, off-road competition use only. Not road legal!
These kits do not contain instructions, they are intended for race technician installation. EDR Velocity stacks are best installed with some heat (DO NOT MELT WITH HEAT GUN) and you can install in under 20 mins time. NO cutting required!
PLEASE NOTE: As of Summer 2026 due to extremely high demand your velocity stack order may take5-7 business days lead time. We fulfill all orders in the order received. These are custom made for you and as such do take some time.
