Now all this being said, engine displacement is not a very good way to judge the size of a motorcycle cover. Take for example the humble 650 Suzuki V-Strom. Only 650cc engine, but it's a long, tall bike. It needs a pretty big cover. On this page see a picture of the 650 V-Strom with the size XL cover.
