what is cruiser motorcycle ?

A cruiser is a motorcycle in the style of American machines from the 1930s to the early 1960s, including those made by Harley-Davidson, Indian, Excelsior and Henderson. The riding position usually places the feet forward and the hands up, with the spine erect or leaning back slightly.

Cruisers are like sedate choppers—their fork rake is less extreme, and they're designed for laid-back riding. Cruisers have come to exemplify a typically American image, and exude an air of cool style.
