Velocity Stack Kit
SKU: BTM-G3-BUSA-STK
Easy — 1–2 hours
Description
The factory velocity stacks on the Gen 3 Hayabusa are designed for low-end torque and daily response, but they limit the engine's top-end power, potentially causing a loss of nearly 30HP as the RPMs increase. BT Moto's modified stacks provide a bolt-on solution to improve this, offering gains comparable to internal engine modifications.
