Powertronic FuelX for Yamaha 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
