Product Description
The WH-RE02B Wiring Harness is the primary electrical backbone for mid-generation UCE (Unit Construction Engine) motorcycles. It is specifically engineered to support the TCI (Transistorized Coil Ignition) system and the high-current demands of the electric starter motor used during the 2013–2014 period.
Unlike generic harnesses, the Motherson WH-RE02B features cross-linked polyethylene (XLPE) insulation, which offers superior resistance to engine heat and chemical exposure (oil/petrol) compared to standard PVC. The assembly includes all critical branch lines for the headlamp, instrument cluster, tail light, and battery charging system, ensuring a complete “cradle-to-grave” electrical restoration for your motorcycle.
Key Features:
-
OEM Manufacturer Quality: Motherson’s expertise as an original equipment supplier ensures 100% accurate wire gauges and connector pin-outs.
-
Heat & Flame Retardant: High-grade sleeving protects the copper cores from the intense heat radiating from the UCE cylinder head.
-
Integrated Tail Light Harness: Unlike some basic kits, the WH-RE02B typically includes the extended rear section for the tail lamp and indicators.
-
Waterproof Couplers: Features high-quality plastic housings with internal seals to prevent “greining” (corrosion) at the connection points.
-
Optimized Grounding: Includes heavy-duty earthing points to reduce “starting trouble” and flickering neutral lights.
