This is a metal rack for attaching to the back of a Honda CBR-250R. It's rather expensive, but all the racks for that bike are. The rack is sturdier than I expected. I use it with a top case for my helmet, which mounts to the rack. Be aware that if you put anything heavy on the back of the CBR-250R, your control will decrease, especially when cornering. If you want to carry heavy things on the bike, don't buy this rack. Get some saddle bags instead.
