2014 Kawasaki Ninja ZX-6R, thousand invested! - Continuing the Family Tradition of Dominance What’s in a number? Only everything. Six percent may not sound like much, but it is the displacement advantage the 2014 Ninja ZX-6R supersport has over the rest of the 600 cc class. This performance advantage began over a decade ago with the first 636, a revolutionary machine that blew-away the competition’s 600’s and won races against factory 750’s on the track. The 2014 ZX-6R continues family tradition of racetrack dominance and unmatched street cred with its physical embodiment of the family slogan: Performance Counts!
