BT MOTO VELOCITY STACKS AND MAP UPGRADE

2026-2027 APRILIA RSV4 (ALL MODELS)

Through careful testing of the stock ECU on our recently acquired 2026 Aprilia RSV4 Factory 1100, we have decoded an otherwise NEW stout 222HP powerplant and ecu for even more rider enjoyment. Stage 2 takes our already potent Stage 1 Tune and turns it up to 11 with a airflow modification and calibration to suit (velocity stack + map)

With full in-person datalogging in our closed dyno cell, we were able to find what the engine really liked and disliked and what it wanted for airflow modifications. Through careful logging of ignition timing, per cylinder fueling and thermal management limiters, we were able to write an excellent calibration for these airflow mods.

ALL THE BENEFITS OF STAGE1 PLUS STAGE 2

• Designed for airflow modifications, filter, velocity stack and a slip on at minimum.  Best with a complete Akrapovic or SC system for full maximization - increased power across the curve.
  
• +7hp over the curve on 91 or VP fuel
• 215whp on pump and 222+whp on VP fuel
• 200+MPH capable on GPS - 3.6 60-130MPH, 3.4 100-150MPH recorded on full weight ( SEE VIDEO )

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 give a very decent top-end power increase, but also doesn't lose 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 perfectly for this bike. We spent months testing and developing these 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.

BENEFITS

• Custom velocity stack designed for YOUR 2026+ airbox. No one size fits all approach. These are designed for the 2026 new airbox and throttle bodies, a completely different design from our 2021+ style.
• OEM fitment and ability to go back to stock whenever you'd like. Plug and play
• Gain 3+HP by itself, more with map (depending on bike and mods) at higher RPM's (with BT Moto Flash).
  
• 215mph and 220whp capable on VP fuel with Stage 2.

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.
