2026 DUCATI DIAVEL V4 RS ​

The Ducati Diavel V4 RS is a great addition to the Ducati lineup and really setst the bar high. At BT Moto, we take bikes that are already amazing and make them spectacular. The Ducati Diavel V4 RS is no exception. We had to re-develop fuel map strategies from square one. Ignition maps and throttle mapping are also all new for the Diavel V4 RS. One of the big complaints was the twitchy throttle that could make the bike buck in a corner along with the big torque HOLE from 4-8,000rpm. The next issue is the exhaust valve problem, bad start and idling, and low power at midrange due to extremely lean fueling.

WHAT DOES STAGE 1 INCLUDE?

• Correct fueling on both banks in “Alpha N” mode for a totally different riding experience
• Better quick shifter / blipper reactive time
• On / off throttle optimization. Bike will no longer jerk from throttle inputs (BT Moto exclusive)
  
• Cold start fix (BT Moto exclusive)
• Unique cylinder deactivation adjustment and refinement
• Raised rev limiter / speed limiter
• Throttle limiters open to 100% and much more responsive from part to full throttle
• Raised torque limiters for lower gears, full power in first gear now.
• Raised load limiters for additional airflow.
• Revised traction control and ABS (BT Moto exclusive)
• Ignition timing adjustments for additional power
• Exhaust valve adjustments
• Engine fan-on temps reduced to 190*F from 220*F

Anyone that has the Akra up-map will say the bike feels a lot more lively than stock. So how does our Stage 1 flash compare? Customers and our own R&D reveal a VAST improvement over the stock map and even the up-map from Akra.

WHY IS THIS THE BEST UPGRADE YOU CAN BUY?

We all know the Ducati Diavel V4 RS is a great bike! We also know it isn’t perfect. Issues that we’ve tested ourselves and what customers have reported include the following:

• Stalling for no reason during idle
• Startup issues when slip on exhaust is installed
• Smoking issue and hard starting in all temperatures
• Issues with slip on exhaust is installed
• Acceleration that isn’t smooth through the entire RPM range due to inaccurate AFR
• Engine seems to struggle (lurch or jump through RPM range, 4000 - 8000 RPM) if too warm
• Power that seems to level off (flatten) after 8,000 RPM heavily

SO WHAT DO WE DO ABOUT THIS?

After extensive R&D with our own, in-house Diavel and select “beta” testers, we can confidently say that we successfully addressed each issue and improved every performance aspect of the Diavel.

• No more stalling at idle for no reason
• Fuel cut off / throttle fixed (BT Moto exclusive feature)
• No startup issues with exhaust installed
• Acceleration is now smooth through the entire RPM range
• Engine performs the same with the engine warm or hot
  
• No problematic fault codes or limp mode with tuning

Don't be fooled by imitations with empty promises, see why everyone uses us:
