The FuelX Lite is a “fit-and-forget” fuel injection optimizer specifically designed for the Yamaha R15 V3 BS6 (2020–2021). While the V3 is famous for its high-revving performance and Variable Valve Actuation (VVA), the BS6 emission standards often lead to a lean fuel mixture, which can cause low-end jerkiness and higher engine temperatures.
The Lite version provides a single, intelligent Autotune Map that works in real-time to optimize fueling, ensuring the 155cc engine stays smooth, responsive, and cool without the need for manual adjustments.
Key Features
-
1 Intelligent Autotune Map: Features a dynamic fueling profile that automatically adjusts based on your riding style, engine load, altitude, and ambient temperature.
-
Smoother Low-End Response: Significantly reduces the jerky “on-off” throttle transitions often felt in low gears and city traffic. This results in a much more refined and manageable ride at lower speeds.
-
Cooler Engine Operation: By correcting the lean factory fuel mixture, the FuelX Lite helps the liquid-cooled engine run up to 10% cooler, preserving engine health during high-RPM riding or heavy traffic.
-
Seamless VVA Activation: Provides a more linear power delivery and ensures a smoother transition when the Variable Valve Actuation (VVA) kicks in, eliminating the “flat spots” found in the stock factory tuning.
-
Adaptive Intelligence: The unit smartly adapts to hardware modifications, such as performance air filters or aftermarket exhausts, ensuring the engine always maintains a safe and optimal Air-Fuel Ratio (AFR).
-
Plug-and-Play Installation: Comes with a model-specific harness and OEM-quality connectors. No wire cutting or permanent modifications are required, making the installation 100% reversible.

Why Choose FuelX Lite for Your R15 V3?
-
Simplified Performance: Ideal for riders who want an immediate improvement in engine refinement and throttle response without the complexity of manually managing multiple maps.
-
Engine Longevity: By preventing the engine from running too lean, the Lite version protects internal components like valves and spark plugs from excessive heat damage, acting as a safeguard for your motor.
-
Discreet & Reliable: The compact module is designed to be tucked away under the seat. Because it uses original factory connectors, it can be removed before service visits to keep the bike’s stock status and warranty intact.
Installation Note
The FuelX Lite connects directly into the motorcycle’s O2 sensor circuit. The setup is straightforward and can typically be completed in under 20 minutes with basic tools. Once installed, it works silently in the background to provide a consistently optimized riding experience.
