FEEL THE DIFFERENCE IN EVERYDAY RIDING
The focus is rideability: how your motorcycle responds in traffic, through slower corners and as you roll back on the throttle.
Helps address abrupt low-speed throttle response for a more settled ride.
Autotune responds to changing operating conditions within the system’s supported range.
A compact module and bike-specific harness connect into the oxygen-sensor circuit.
Results depend on the motorcycle, condition, setup and FuelX version. FuelX is not a repair for an underlying engine fault.
UNDERSTAND THE UPGRADE
FuelX adjusts oxygen-sensor feedback used by the ECU during closed-loop operation. It is a fuel optimiser, rather than a full ECU replacement.
The correct harness plugs into your motorcycle’s oxygen-sensor connection.
The module modifies feedback to support revised fuelling during closed-loop riding.
The intended result is more refined throttle behaviour in everyday use.

Manufacturer installation guides ↗BEFORE YOU ORDER
Use the model and year in this listing, then match the emissions and connector version. Do not assume that two motorcycles with the same engine size use the same harness. Contact LRL Motors if any detail is unclear.
No. FuelX works through oxygen-sensor feedback during closed-loop operation. It does not offer the full fuel and ignition control of an ECU remap or a separate programmable ECU system.
FuelX can be used with supported stock motorcycles. Compatibility with modifications depends on the motorcycle and setup; confirm your particular combination before ordering additional parts.
Neither is guaranteed. Results vary with the bike, riding conditions, modifications and map selection. The core reason to consider FuelX is its intended effect on rideability and throttle response.
The harness is designed for a plug-in connection, but reaching and routing the connectors differs by bike. Use the exact model’s installation manual and a qualified installer if you are unsure.
