Compatible with the magneto-stator of the Yamaha LEXI 125 / AEROX 155 motorcycle, original reference number B63-H1410-11

This product is an original magneto ignition coil (alternator coil), specifically designed for Yamaha LEXI 125 sport scooters (with variable valve timing, VVA) and AEROX 155. It is an exact match for the original part number B63-H1410-11 and meets the high performance and efficiency requirements of the Blue Core engines and VVA systems in these models. This product is an essential component for reliable starting, lighting, and stable operation of the electronic VVA control system in sport scooters. 【Product Information】 Original Part Number: B63-H1410-11 Compatible Models: Yamaha LEXI 125 (also called LEXY 125 in some markets, with variable valve timing, VVA) Yamaha AEROX 155 (some international models) Note: Please check if your model is equipped with a VVA system and ensure you are using the correct original part number. Ignition coils may vary depending on the market and model configuration. Engine technology: 125cc/155cc SOHC Blue Core four-stroke engine with variable valve timing (VVA). Component function: This product is the primary power generation component for the magneto ignition. At certain engine speeds, stable and lag-free switching of current is required for the operation of the VVA system. This product generates a stable three-phase power supply that primarily powers the following systems: Electronic VVA control system: Delivers precise operating voltage to the solenoid valves and VVA regulator, ensuring smooth valve timing. Electronic fuel injection system: Supplies power to the engine control unit (ECU), fuel injectors, and throttle position sensor. Charging and lighting system: Charges the battery and powers the LED lighting and instrument panel. Symptoms of resolved faults: This product is designed to resolve typical faults caused by a damaged stator coil: difficulty starting or inability to start the vehicle electrically. Illuminated fuel injection system warning light, indicating a possible VVA system malfunction. Unusually rapid battery discharge. Dim or flickering low beam headlights and instrument panel lights. Uneven power supply while driving (possibly due to an unstable VVA power supply).
