What Is Stage 1?

Introducing our flash for the 2021+ BMW S1000R! Utilizing our decade of experience and research into the BMW ECU's has helped us A LOT to develop the 2021+ S1000 Single R Stage 1 Flash. US and European model S1000R’s have been restricted from the factory, with the US models having some of the worst restrictions we have ever seen on a BMW liter bike short of the 2017+ BMW K1600.

What's Being Restricted?

• Throttle Restriction - Throttle is restricted and has a lazy feel on tip-in riding along with loss of power in certain gears / RPMs
• Exhaust Valve - Restricted to keep quieter, which results in power loss
  
• Fueling - The 2021+ BMW S1000R fueling is set rich from the factory and needs adjustment
• Heat Management - The S1000R feels hot and runs hot

What Do We Do To Fix These Issues?

• Throttle Restriction - We remove the throttle restrictions across the board to give you the riding experience and power you wanted from the factory
• Exhaust Valve - We still utilize the stock exhaust valve to give you maximum power but also open it up when you need to make peak power gains
  
• Fueling - We program the S1000R to target a better AFR (Air/Fuel Ratio) to make a little more power along with fixing drivability and idle issues
• Heat management - We turn the fans on early and adjust the fueling to a proper ratio to make for a cooler running, more consistent bike.
• Please note: Our stage 1 tuning is certified 50 state legal by CARB EO D-868. As of July 2025, we no longer offer extended rev limiter options on stage 1 tuning. Stage 1 is designed to for OEM dealer level serviceability and to abide by BMW's warranty standards. For race use please consider our stage 2 mapping upgrade.
• For maximum results please consider using our velocity stacks on this motorcycle.
