FAQs on FuelX
Is FuelX safe for my bike engine?
FuelX compatibility depends on the exact motorcycle model, year and sensor setup. Use only a unit listed for your bike and follow the manufacturer installation instructions. A collection-wide description cannot guarantee suitability or engine safety for every setup.
Will FuelX improve my bike mileage?
Fuel consumption depends on the motorcycle, installation, settings, riding conditions and maintenance. A mileage increase is not assured. Check the specifications of the model-matched FuelX unit before choosing it.
What is the difference between FuelX Lite and FuelX Pro+?
FuelX Lite and FuelX Pro+ are different variants. Compare the current manufacturer specifications and product listings for supported settings, controls and motorcycle compatibility. Do not assume that a particular power increase will result from installation.
Will installing FuelX void my bike warranty?
Motorcycle warranty terms vary. Check the applicable written terms and consult your motorcycle dealer before installing FuelX; plug-in installation does not by itself establish that warranty coverage is unaffected.
Can I install FuelX myself?
Follow the installation instructions for the exact FuelX unit and motorcycle. If you are unsure about connectors, routing or testing, have it installed by a qualified mechanic.
Do you provide a refund policy if I order the wrong variant?
Review the current published refund policy for return eligibility and conditions. Contact support with your order details if you selected the wrong variant or need help with a compatibility issue.
What is FuelX and how does it work?
FuelX is a model-specific fuel injection optimiser used with a motorcycle's ECU and oxygen-sensor system. Check the selected unit's documentation for its connection method, supported motorcycle and installation requirements.
What is the difference between FuelX Lite and FuelX Pro+?
Compare the current FuelX Lite and FuelX Pro+ product listings for their settings, controls, model coverage and price. Features can differ by version; use the documentation for the exact unit you are considering.
Which bikes is FuelX available for?
FuelX is model-specific, so each unit is matched to your bike's exact model, generation and O2 sensor setup. RKD Bike Accessories lists FuelX for Royal Enfield, KTM, Triumph, Yamaha, Bajaj, Harley-Davidson, Suzuki, Honda, Aprilia, Husqvarna and Jawa/Yezdi models, such as the KTM Duke 390 and Hunter 350. If your model isn't listed, contact support.
Is FuelX safe, and will it affect my bike's warranty?
Confirm the model, year and sensor compatibility of the selected FuelX unit and follow its installation instructions. Check the motorcycle's written warranty terms and consult your dealer before making changes; neither safety nor warranty coverage can be guaranteed for every setup.
