Yuasa all the way. Can’t go wrong.2012 Yamaha FJR Gen II 35,000 miles. I live in New York City and ride everyday year around in 15 degrees as long as bike starts. Bike wouldn't start this morning. I park on the street and can't use a tender. I've never changed the battery. I'm ready for a new battery asap. Recommendations please? I really don't care about cost or weight. I want reliable and asap.
