2021 APRILIA RSV4 X / TUONO X STAGE 1+

WHY CHOOSE BT MOTO

Through careful logging of ignition timing, per cylinder fueling and thermal management limiters, we were able to write an excellent file that is powerful in all temperatures and covers all octanes. Coming with the Factory 1100 engine, the X is an extreme powerhouse. Coming stock with the Aprilia Race ECU and a lightened body, the Tuono and RSV4 X are both already extremely potent. After reviewing the Race ECU data, we were able to determine some impressive improvements could be found with time invested in a proper calibration. We were able to get larger gains under the curve and top-end improvements on pump and race fuels.

ONE TUNE FOR ALL

​Racers at the circuit tracks or the drag strips will appreciate this tune. Thoroughly tested in both aspects by track racers, roll racers and just the casual rider wanting a more exciting bike to ride. 

TRACK RACERS

Track racers can enjoy modified TC (traction control) settings for different tire sizes, smoother throttle transitions/tip-in, consistent and predicable power. All this comes together to make sure you start and finish a turn to the best of the bikes capability. Working directly with MotoAmerica racers really helped us dial in our products for the track.

DRAG / ROLL RACERS

Drag racers have the capability to restrict throttle in first and second gear to make managing wheelies easier. For more top-end than others, we adjust timing, fueling, FTCL (full-time closed loop), SOI (start of injection), EGT, the list goes on and on. Years of experience have helped us squeeze every bit of power from the bike, while keeping it reliable and consistent.

STREET RIDERS

For the casual rider, derestricting the bike is the biggest advantage to our tuning. This makes the bike a blast to ride and gives the rider smile educing power. The throttle is smooth when cruising and brutal when you need it to be. Hundreds of hours and miles go into our tuning and testing. We want to present the best product on the market while leading the pack in customer satisfaction.

ADVANTAGES WITH STAGE 1

• On average, gains of 7-HP 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 – At 200 degrees, your Aprilia starts to pull power from the engine. We change this to 185 degrees to avoid this power loss in stop and go traffic
• Changes to fueling including part, mid and full-throttle while in Alpha-N configuration per cylinder
• Optimization of ignition timing at part and mid throttle for all fuel qualities
• Adjustments to torque limiting to allow the bike to make 100% of its available engine torque at high load
• Changes to rev limiter per-gear tables for widest and safest possible powerband as the factory 1100 cuts short in lower and upper gears
• Aggressive adjustments to engine braking along with decel fueling for road course use
• Changes in factory unstable engine idle for stability and consistency off-throttle
• Changes to a full 100% throttle opening in all modes, versus a limited tabl
• Gains throughout the whole curve on all fuel qualities with no loss in power anywhere on the RPM band
• Changes to ABS, DTC, and wheelie intervention for more available power and control for a performance oriented rider
