The 636 cc fuel-injected ZX-6R listed for 2004, with the same 118 hp engine and aluminium twin-spar frame as the 2003 model. It used 46 mm cartridge forks and 300 mm front discs, with Bottom-Link Uni-Trak rear suspension. The page's text describes the 2003 bike, so the 2004 entry is effectively the same specification.
