My ride is a 2019 CB1000R+ with 3K miles. So here is my tail...I was out for an evening ride to the coast a few days ago, covered about 50 miles, it was a bit chilly (usually is in England) so heated grips (standard factory fitmant) were turned on to level 3. I stopped near home to re-fuel, turned ignition on and a flat battery. Got the bike home and put it on charge, with the bike running the multimeter is showing 14.4 volts so charging system is working ok.The battery is the original Yuasa YTZ10S. Question is what....If I purchase a new battery which is possibly the problem, what should I get?
