I met a guys yesterday that said he would buy a new Challenger tomorrow if he could get a rear tail bag/seat rest that would hold 2 full face helmets. I have to be honest, I sat on a new Roadmaster and it felt like it weighed 400 lbs more than my Challenger or my Springfield. With a lot of us getting older that excess weight is a factor. I saw someone post a chopped box with a website, but when I punched in the Indian Challenger, nothing came up. Does anyone have this setup with a full size rear box?
