Just an FYI note to anyone considering the White Bro's slip ons. Apparently White Bro's has ended production for the Harley market and is going back to their dirt bike roots (greater volume products). White Bro's themselves no longer has any of the slip ons remaining so what is left in the vendors hands will be what is left.
I've used them on a few bikes for a couple of reasons. I like the look and (as importantly) the local dyno guy (John Golden, Rolling Thunder Dyno) has always highly recommended them for touring bags and does good things tuning with them. So I was disappointed to hear they might not be readily available too much longer. Anyone, not affiliated with White Bro's, any vendor, yada yada yada, just passing it along.
