R15 V3

The R15 V3's stock mapping runs lean out of the box, which is why the throttle can feel jerky at low speed or the bike stalls at a standstill. The FuelX plugs into the stock harness and constantly recalibrates fueling in the background, so the engine settles into a smoother, more usable delivery without any of the guesswork of a full remap.

It learns as it runs, adapting to engine wear, riding style, and add-ons such as a freer air filter or exhaust, as well as environmental factors like temperature and altitude. Ten switchable autotune maps let you match the tune to how you actually ride. Installation is plug-and-play, and the unit is sealed against water, heat, and shock.

Day to day, that means fewer stalls at junctions, less need to downshift to keep momentum, and a throttle that responds the moment you ask it to, all while keeping the engine running cooler.

What it does:

• Reduces jerkiness and stalling at low speed
• Reduces the need for downshifts
• Increases usable torque and improves throttle response
• Ten switchable autotune maps for different riding needs
• Plug-and-play installation, water and shock resistant
• Keeps the engine running cooler for the long run

Stock fueling on the R15 V3 is tuned lean to meet emission rules, which shows up as flat spots, jerky low-speed response, and hesitant throttle pickup. The FuelX Pro plugs straight into the stock harness and recalibrates the air-fuel ratio in real time so the engine actually delivers the power it has, smoothly and predictably.

It works by continuously reading engine condition, riding style, and add-ons like a freer-flowing air filter or aftermarket exhaust, then adjusting fueling to match. Ten switchable autotune maps let you pick a setup for daily riding, spirited riding, or whatever mods you've added, and the unit keeps learning and adapting as those conditions change. Installation is plug-and-play with no cutting or splicing, and the housing is sealed against water, heat, and vibration.

The result for the rider is a bike that pulls cleaner off idle, holds gears longer without needing a downshift, and just feels calmer to ride in traffic or on a spirited backroad, without any of the guesswork of a full remap.

What it does:

• Smooths out throttle response and reduces jerkiness at low speed
• Increases usable torque and reduces the need to downshift
• Ten switchable autotune maps for different riding needs
• Automatically adapts to air filter, exhaust, and riding style changes
• Plug-and-play install, water and shock resistant housing
• Works reliably across altitude and temperature changes
