My bf has a 2003 Harley Davidson 883R and he wants new rims for it. I´m looking around to see what I can find to get him for his birthday, but I don´t know the measurements for the wheels. The wheels are stock, he hasn´t changed them, I just don´t know how many inches they are. Also, does anyone know how big of a rim you can put on an 883? Like if the rims are 18\
