Kawasaki Ninja ZX-6R 636 (1st gen, 2003-2007) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki Ninja ZX-6R 636 made between 2003-2007 (Looking for the later ZX-6R 636 made from 2013 onward?). During that period Kawasaki also made the Kawasaki Ninja ZX-6RR with 599cc, to satisfy racing requirements.

The Kawasaki Ninja ZX-6R was introduced in 1995 and has been constantly updated throughout the years. The year 2003 was the first time Kawasaki used the 636cc “cheater” displacement for their road motorcycles (replacing the earlier 1998-2002 Ninja ZX-6R), gaining a power and mid-range torque advantage over the middleweight supersport rivals.

The ZX-6R stayed largely the same in between 2003 and 2004. In 2005 Kawasaki surprised everyone by re-doing the 636 already, giving the motorcycle a re-tuned engine (larger cams, a new head, polished ports) to give it a quite insane 130 hp, plus a slipper clutch, upgraded suspension, new wheels, better brakes, oh and also that sweet under-seat exhaust.

General information about the Kawasaki Ninja ZX-6R 636

The Kawasaki Ninja ZX-6R had already made a name for itself.

Expanding to 636cc was an unuisual move for Kawasaki, but one that let it get a power and mid-range torque advantage over its rivals. For street riders for whom complying to a 600cc maximum wasn’t a critical requirement, this was a win.

The Kawasaki ZX-6R636 (2003-2007) had Ram Air, an under-seat exhaust, petal-style disc brakes, inverted forks, striking looks.

For the 2006 model year Kawasaki has also added a ZX-6R “Special Edition” model with titanium silver paint and a different wheel finish.
