As far as our econo-shootout's winner, no envelope needed. The Kawasaki. Reasons? First, the Ninja is a bargain at the list price. Kawasaki has been making this model for years, and all the tooling is paid for. Two, it's right in the middle of the mpg chart. Three, it's a real, full-time motorcycle. Wins admiring glances from those who know bikes, fast enough for any freeway, light enough for city combat and, heck, the clincher here is that the Kawasaki racked up three times as many miles during the test period as any of the others, because the panel rode it even when they didn't have to.
