Whether you refer to them as "naked" bikes or "standard" bikes, the look says it all for these motorcycles that emphasize power, back road agility, and a certain type of rider individuality. Kawasaki's Z1000 is no exception to this rule, and rightfully takes its place among the most desired of this breed of "nakedness."The Z1000 backs this aggressive, super naked style with an in-line four-cylinder, DOHC 16-valve engine, which produces tractable power for hard acceleration in any rpm range.
