Ultima Street Motorcycle Editorial Review

This is a 18x5.5 black fat tire rear wheel that is compatible with Harley Softail Rigid Choppers with a custom design for a 200 tire. However, based on the FAQ section, this product does not fit on various models of Harley Davidson bikes such as Softail Slims, Night Trains, and Dynas. Nevertheless, based on customer reviews, this product is comfortable and great for sports activities such as gym use.
