This is a modified velocity stack for a 1998 Honda Super Hawk motorcycle, which I designed with a smoother lip around the outside edge for minimized turbulence of air flowing into the engine. These velocity stacks fit into the motorcycle with zero modification, and perform just as well (if not slightly better) than the stock velocity stacks.
