I have for going on 27 years used a back pack while riding. Does well for toting lunch, water, most anything. Bear in mind that, predominately speaking here, I have owned Sport Bikes. Fast forward to my new High Ball. Unfortunately for me, I noticed to late that my Back Pack was riding on my rear fender. This resulted in scratches. Not cool in my book. It's something I never thought of due to the fact that I have been using a back pack for so long. I ordered my new Ginz Choppers Sissy Bar/Luggage Rack todaythumb up, but none the less. Just a little heads up for those of you planning on using a back pack on your High Ball.
