The 25th Anniversary ZX-6R marked 25 years of the Ninja name and was a special build from Kawasaki Motors UK. It carried a Dream Machine paint scheme and a set of visible upgrades, including a road-legal Akrapovic exhaust, LSL rearsets and a seat cowl. The mechanicals were those of the standard 2009 599 cc bike.
