(2026) Aprilia RSV4 BT Moto Velocity Stack Kit

THIS PRODUCT IS VELOCITY STACKS ONLY. NO TUNING IS INCLUDED WITH THIS PRODUCT

2026 Aprilia RSV4 Velocity Stack Kit

With the success and amazing feedback we've gotten from our 21-24 Aprilia velocity stacks, we wanted to take advantage of the new 52MM throttle bodies that are begging for more air. Our custom revised velocity stacks and revised tuning not only gives a very decent, top-end power increase, but also doesn't loose any power in the low or midrange of the RPM. Our easy to install, custom velocity stacks don't shift the powerband over and decrease power down low. We managed to make more power where it matters without sacrificing that torquey punch we've grown to love on the RSV4.

Experimenting with many designs, we found a design that works perfect for this bike. We spent months testing and developing this stack designs. We have found this design makes the best power for the RSV4 (dyno results below). With our custom stack tuning, there's no need to worry about your bike having rideability issues either.

BT MOTO APRILIA VELOCITY STACKS

Custom composite with our logo and torqueing specs etched into them, the BT Moto Velocity Stacks have been carefully engineered and designed to maximize power in the higher RPM range while not losing power in the low RPM range.

Made for an OEM fit, the BT Moto velocity stacks bolt to the airbox to ensure tight fitment while also being easy to install. These are plug-and-play and require no additional modifications to your airbox to fit. Simply remove your factory velocity stacks and install. Coupled with our custom flash, the combination makes an extremely easy install and tune that can be done in your own garage, with basic tools and minimal mechanical knowledge.
