FuelX by Race Dynamics is a closed-loop autotune fuel controller for modern fuel-injected motorcycles. It reads the factory oxygen sensor in real time and corrects the air-fuel ratio continuously, so the engine runs the mixture it actually wants rather than the one emissions regulation demanded.
The result is smoother part-throttle response, fewer flat spots and cleaner fuelling through the mid-range. No laptop, no dyno, no tuning session. Installation is plug and play into the OEM harness, with no cutting and no permanent modification. Unplug it and the motorcycle returns to stock.
Free shipping across India on every FuelX module.
FuelX Lite delivers automatic closed-loop correction for a stock or lightly modified engine. FuelX Pro+ adds a wider correction range and adjustable richness levels, built for bikes running an aftermarket exhaust or air filter.

Frequently asked questions
What does FuelX do?
FuelX is an autotune fuel controller that reads your bike's O2 sensor and adjusts fuelling in real time for smoother response and better part-throttle running. It is plug and play, with no tuning needed.
FuelX Pro+ or FuelX Lite, which should I choose?
FuelX Lite delivers automatic fuelling correction for a smoother ride. FuelX Pro+ adds adjustable richness levels for finer control, which suits riders running an exhaust and air filter who want more tunability.
Do I need FuelX with an exhaust and air filter?
For a full Stage 1 setup, yes. Adding airflow without adjusting fuelling can run the engine lean. FuelX keeps fuelling smooth and safe as you upgrade breathing.
Which bikes does FuelX fit?
FuelX covers many popular fuel-injected bikes including the Royal Enfield 650 twins, Himalayan and Guerrilla, KTM Duke, RC and Adventure, Honda CB350, Triumph 400 series, Bajaj Dominar, Hero XPulse and Yamaha. Check the listing and ask us for fitment guidance.
