Unless you have a angled screw driver that will fit between the wheel and the fender you will need to remove the wheel. Takes 5 minutes to remove the wheel. Hardest part was getting the chain guard off. All the screws have that lock tight on them and the front screw for the guard was **** near impossible to get off. Luckily I was changing out the rear fender also so it was easier with the fender off.For those of you that have installed the BC turn signal kit, did you have to remove the rear wheel or just use alan key to get in behind?
