BT MOTO VELOCITY STACKS AND MAP UPGRADE

2026 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 full in-person datalogging in our closed dyno cell, we were able to find what the engine really liked and disliked. Through careful logging of ignition timing, per cylinder fueling and thermal management limiters, we were able to write an excellent calibration that is powerful in all temperatures and covers all octanes including poor California ACN91. 

ADVANTAGES WITH 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. 
• On average, gains of 5-15HP from the midrange and up were found over the baseline on a typical exhaust/filter bike with 93 octane fuel in the tank (Larger gains with race fuel)
• Early Fan-On. Your Aprilia starts to pull power from the engine with high temps. We change the fan-on to 194 degrees to avoid this power loss and stalling from overheating in stop and go traffic. Most RSV4s push coolant in factory form and at redlights, this fixes it
• Changes to fueling including part, mid and full-throttle while in configuration, per cylinder
• Optimization of ignition timing at part and partial throttle for all fuel qualities
• Adjustments to torque limiting to allow the bike to make 100% of its available engine torque at high load
• RPM limiter raised from 13,600RPM to 14,200RPM (optional)
• Changes to rev limiter per-gear tables for widest and safest possible powerband as the Factory 1100 cuts short in lower and upper gears
• Exhaust valve adjustments for more power and torque with stock valve installed
• Changes in factory unstable engine idle for stability and consistency off-throttle
• Changes to a full 100% throttle opening in all modes and torque logic, versus a limited table per gear

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.

BENEFITS

• Custom velocity stack designed for YOUR 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 when ever you'd like. Plug and play
• Gain 3+HP (depending on bike and mods) at higher RPM's (with BT Moto Flash).
• 2mph trap speed increases in half mile 
  
• 200mph capable on VP fuel.

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.
