Whichever side is without a saddlebag, line that side of BOTH wheels completely around with stick on wheel weights. These weights MUST be purchased at an authorized Harley Davidson dealer (warranty issues). The weights will counteract the coefficient of drag placed on your motorcyle by the remaining saddlebag. When you get the other bag back from repairs be sure to REMOVE all of the wheels weights you put on. Failure to do so will result in you only being able to ride in circles!
You probably won't even notice a difference. Although the coefficient of drag argument seems plausible. You might wear out one side of the tires faster as the bike tips to compensate from the additional drag.
Hey, tencrore started it.
If you ride without one bag, you'll likely throw out your back and neck from over-compensating the weight differential.
Hey, nothing can be worse then seeing graded papers flying down the road. Don't ask, just ride.
Take the other bag off and strap the stuff to your back.
Just a hint; never wear a pink shirt while riding your Harley.
