Im looking at replacing the battery on my 06 K12R. Bike has 38000 miles and I have owned bike since new. No starting issues yet but have noticed that the little battery icon stays on screen for a few more seconds that I was used to. I have not needed to use the battery charger to keep voltage up. battery voltage 24 hours after a long ride is now at 12.3 volts. So just a new battery or look further for something else?
