Just purchased a 2019 K1600B. The covers I have for an RT and a GSA do not fit. The issues seem to be that the B is a bit longer and the rear is substantially wider due to the bags. I'm looking for a rain cover, rip-stop nylon, waterproof and light in weight as I pack it while touring. Not for trailering. Only have a few hundred miles on it as I just picked it up. So far very impressed and look forward to more time on it. Any input would be greatly appreciated.
