At a glance
The Carrot MX wiring loom is a direct Spec55 replacement for the factory wiring of modern KTM and Husqvarna MX bikes. The stock harness was never designed for the environment it lives in — mud, water, dust, fuel, oil, vibration, and heat — which is why electrical failures are so common on these machines.
We rebuild the loom from the ground up using TE Spec55 wire (mil-spec M22759/32), a shielded M27500 cable for the crank sensor, Raychem DR25 heatshrink, System 25 molded boots, and RT125 epoxy at the critical junctions. Every section is concentrically twisted so the harness moves without stressing any single conductor.
The original connectors are reused — modified so they actually seal — which keeps the harness genuinely plug-and-play. No adapter spaghetti, no custom ECU work. Install it like the factory one; it just won't fail like the factory one. A side benefit of the Spec55 build-up: roughly 10% less weight than the harness it replaces.
Compatible with KTM 125/250 SX and Husqvarna TC 125/250 in the 2023–2024 model years.
