The FuelX Pro is the premier performance fuel injection optimizer specifically designed for the Yamaha MT-15 BS6 (2021–2023). While the MT-15 is known for its aggressive street-fighter agility, the BS6 tuning often leaves the 155cc engine running “lean,” resulting in low-end jerkiness and higher operating temperatures.
The Pro version transforms the MT-15 experience by offering 10 switchable maps, giving you total control over throttle response and cooling for a sharper, more responsive ride.
Key Features
-
10 Switchable Autotune Maps: Includes a handlebar-mounted switch that allows you to cycle through 10 fueling levels. Prioritize “Economy” (Levels 1–3) for efficient commuting or “Performance” (Levels 7–9) for maximum torque and a crisper engine feel.
-
Handlebar Map Switch: A rugged, weatherproof, and backlit interface that provides instant control. Adjust your engine’s fueling personality on the fly without needing to stop or use external software.
-
Real-Time Autotuning: Regardless of the map selected, the unit constantly monitors engine load, altitude, and temperature to maintain the perfect Air-Fuel Ratio (AFR) for that specific setting.
-
Sharper Throttle Response: Eliminates the jerky “on-off” throttle transitions common in the stock BS6 tuning. This results in a more connected feel and smoother power delivery, especially when the Variable Valve Actuation (VVA) kicks in.
-
Significant Heat Reduction: By correcting the lean factory fuel mixture, the FuelX Pro helps the liquid-cooled engine run up to 10% cooler, which is critical for maintaining peak performance during aggressive high-RPM riding.
-
Adaptive Intelligence: The unit smartly adapts to hardware modifications, such as high-flow air filters or aftermarket exhaust systems, ensuring the engine never runs dangerously lean and protecting internal components.
-
Plug-and-Play Installation: Features a model-specific harness with OEM-spec connectors. No wire cutting or splicing is required, making the installation 100% reversible.

Why Choose FuelX Pro for Your MT-15?
-
Street-Fighter Control: The MT-15 is built for quick maneuvers. The Pro version provides the punchy mid-range torque needed to exit corners with more authority and achieve faster roll-on acceleration.
-
Ultimate Protection for Mods: If you have upgraded your exhaust or air filter, the Pro is essential. It ensures your engine receives the correct amount of fuel to match the increased airflow, protecting your valves and spark plugs.
-
Versatile Riding Characters: Keep the bike in a balanced mode for your daily city ride and instantly switch to a high-performance map for weekend canyon runs or spirited highway sprints.
Installation Note
The main module is typically tucked under the seat, while the waterproof map switch is clamped onto the handlebar for easy thumb access. Because it uses original factory connectors, you can easily remove the unit before a scheduled service visit, ensuring the bike’s stock status and warranty remain untouched.
