How do you develop your parts?
Every design is simulated before it's made, using CFD and simulated flow bench tools we built in-house in Python. See our engineering process.
Why carbon-fiber composites?
We've tested carbon-fiber composites including PLA-CF, PETG-CF, PET-CF, ASA-CF, PA12-CF and PPS-CF for stiffness and heat resistance, and choose the material that suits each part.
Do you only make intake parts?
No. Velocity stacks are where we started. We also make brackets, CNC-machined components, racing parts and custom projects.
How do I know a part fits my bike?
Each product lists the exact years and models it was designed for. Use Shop by Bike to see parts for your motorcycle. If you're unsure, contact us before ordering.
Do I need a tune after installing velocity stacks?
It depends on your bike and setup. Check each product page for install notes, and consult your tuner if your bike is already modified.
What material are the parts made from?
Our velocity stacks are made from carbon-fiber-reinforced engineering polymers. The exact material is listed on each product page.
Do you make parts for other bikes?
We're adding models regularly. See Custom Work to request one.
