WHAT'S INCLUDED

• Recalibrated throttle strategy to eliminate factory-imposed throttle restrictions, delivering maximum torque and immediate throttle response.
• Increased horsepower and torque through optimized throttle control and the removal of factory torque and gear-dependent performance limiters.
• Optimized ignition calibration for compatibility with multiple fuel grades while maximizing performance and maintaining engine safety.
• Restored full throttle authority by removing low-RPM throttle limitations, allowing a true 100% throttle opening for more direct power delivery.
• Refined low-speed and part-throttle calibration to significantly improve rideability by reducing bucking, hesitation, and that abrupt feel to throttle transitions.
• Removed factory top-speed limiter to unlock the motorcycle's full performance potential.
• Reengineered torque model for stronger, more consistent power delivery across the entire RPM range at both partial and full throttle.
• Refined engine braking strategy across all riding modes for smoother transitions and improved rider confidence.
• Optimized cold and warm start calibrations to improve starting consistency and overall drivability.
• Eliminated known flat spots throughout the powerband for smoother, more linear acceleration.
