Description
Product Overview
The PROOTOM DFI map wire lead coupler is engineered specifically for Kawasaki KX250 and KX450 sport‑bikes produced between 2012 and 2023. Constructed from high‑grade polymer, the black coupler (part 26011-0728) weighs only 0.634 ounces and measures 2.83 x 2.24 x 1.3 inches, ensuring a compact fit within the bike’s wiring harness. It connects directly to the ECU via the DFI port, allowing riders to select a pre‑programmed engine map that emphasizes smoother low‑range torque while delivering a noticeable lift in mid‑high power for hard packed terrain such as clay or dry dirt. The part is compatible with multiple model years, including KX250 2020‑2024, KX250F 2013‑2021, KX250XC 2021, KX450 2020‑2023, KX450F 2012‑2021, KX450SR 2022‑2023, and KX450X 2021‑2023.
Usage
Designed for off‑road riders who demand precise power delivery, this coupler excels in motocross, enduro, and trail riding where rapid changes in terrain require instant engine response. Install the black plug in place of the factory white or red couplers to shift the bike’s power curve toward a more tractable low end while still retaining strong acceleration in the higher RPM range. Ideal for riders who tackle hard packed, loose, or mixed surfaces and need a bike that feels both controllable and aggressive.

FAQ
Will this coupler work on my 2015 Kawasaki KX250?
Yes. The black PROOTOM coupler is compatible with KX250 models from 2020‑2024, but it also fits earlier years such as 2015 because the DFI port dimensions have remained unchanged.
Do I need to re‑program the ECU after installing the coupler?
No additional programming is required. The coupler simply selects the pre‑loaded engine map stored in the bike’s ECU.
Can I switch back to the factory map easily?
Absolutely. The coupler is removable; simply replace it with the original factory plug to restore the stock power delivery.
Is the installation tool‑free?
Yes. The coupler snaps into the DFI port, and the wiring harness clips securely without any screws or adhesives.
What warranty does PROOTOM provide?
PROOTOM offers a one‑year limited warranty covering manufacturing defects, ensuring peace of mind for your purchase.
