The FuelX Lite is a “fit-and-forget” fuel injection optimizer specifically engineered for the Royal Enfield Hunter 350 (2022–2024). While the Hunter 350 is designed for agile urban riding, its J-Series engine is factory-tuned to run “lean” to comply with strict BS6.2/OBD2 emission standards.
The Lite version provides a single, intelligent Autotune Map that works in real-time to optimize fueling, sharpening the bike’s throttle response and ensuring the engine runs cooler during spirited city sprints or highway cruises.
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.
-
Sharper Throttle Response: The Hunter is built for quick maneuvers. The Lite version enhances this by providing a crisper throttle feel and eliminating the low-end “flat spots” found in the stock factory tuning.
-
Significant Heat Reduction: Lean fueling causes high engine temperatures. The FuelX Lite helps the 349cc engine run up to 10% cooler, which is vital for maintaining performance during heavy traffic or long summer rides.
-
Smoother Low-Speed Manners: It eliminates the jerky “on-off” throttle transitions often felt at low speeds, making the Hunter 350 even more refined and easier to handle in dense urban environments.
-
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-grade connectors. No wire cutting or permanent modifications are required, making the installation 100% reversible.

Why Choose FuelX Lite for Your Hunter 350?
-
Urban Agility: Ideal for riders who want the benefits of a punchier mid-range and smoother low-speed handling 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 wear, effectively acting as an insurance policy for your motor.
-
Discreet Integration: The compact module is designed to be tucked away behind the side panels or 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.
