Compatible with the stator coil, magnet coil and generator charging coil of the Yamaha XT660R motorcycle (2005-2015).

This product is an OEM-quality (OEM-spec) solenoid coil specifically designed for the Yamaha XT660R (model years 2005–2015), a classic single-cylinder off-road motorcycle. It is perfectly compatible with the model throughout its 11-year production run (2005–2015) and has been specially tuned to the unique vibration characteristics and high torque of the 660cc SOHC single-cylinder engine. As a vital electrical component of this endurance motorcycle, this coil provides stable and reliable power to the electronic fuel injection, headlights, and auxiliary equipment, even under demanding road conditions. It is essential for a dependable power supply on long rides and off-road adventures. 【Important Product Information】 Compatible Models: Yamaha XT660R Endurance Motocross Motorcycles. Compatible model years: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015. Important note: This part may be compatible with some XT660X (Supermotor) and XT660Z Tenere (Adventure version) models. However, please check compatibility with your model before installation, as the length or layout of the wiring harness may vary. Engine type: 660cc 4-stroke single-cylinder SOHC engine with electronic fuel injection (EFI). Part function: This product is the primary ignition component. The high pulsations of a large-displacement single-cylinder engine require optimal stability from the ignition system. This product generates a stable three-phase power supply across the entire engine speed range, including low RPMs and under heavy off-road loads, and powers the following systems: Electronic Fuel Injection: Delivers a precise and stable operating voltage to the ECU, injectors, and throttle position sensor, ensuring optimal fuel injection. Charging and Off-Road Equipment: Efficiently charges the battery and ensures stable operation of essential equipment for extended trips, such as headlights, GPS, and USB charging ports. Ignition System: Powers the high-performance ignition coil. Specific Problem Solving: This product helps resolve common XT660R issues caused by a stator coil failure: The battery does not fully charge after a short ride, often resulting in a low charge. Headlights and other lights are unusually dim, especially at idle or during nighttime off-road riding. The vehicle is difficult to start, or after starting, low voltage causes a rough idle and frequent stalling. Symptoms of insufficient power supply occur when using additional electrical devices (such as heated grips or auxiliary headlights). A multimeter test revealed that the charging voltage is constantly below 13.5 V or fluctuates considerably.
