Kawasaki Ninja ZX-6RR (599cc, 2003-2007) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki Ninja ZX-6RR made between 2003-2007.

The ZX-6RR was the 599cc racing stablemate to the Kawasaki Ninja ZX-6R 636 made during the same period. Whereas the “cheater” displacement ZX-6R 636 motorcycle was the street bike (that you still rev the snot out of), the ZX-6RR was the bike dedicated to the track. It’s a similar motor, just with less midrange, but almost as much top end power.

The maintenance schedules for the ZX-6RR and its contemporary ZX-6R are quite similar.

General information about the Kawasaki Ninja ZX-6RR

In keeping with its original concept of No. 1 performance on the circuit, for 2004, the concept of the Ninja ZX-6RR diverges from that of the street-use ZX-6R, becoming even more race-oriented than before. A series of engine and chassis upgrades significantly enhance this lime green racer’s winning potential. The 2004 Ninja ZX-6RR sport motorcycle returns to the 2004 Kawasaki lineup with upgrades to the engine and powertrain for even higher on-track performance.

The ZX-6RR engine is a liquid-cooled, DOHV, 16-valve, 599cc, four cylinder, four-stroke engine that delivers performance worthy of AMA Supersport competition. To give racers and sportbike enthusiasts even more power, Kawasaki engineers changed the shape of the combustion chambers, redesigned the piston crowns and added molybdenum coating to the skirts to reduce friction and mechanical loss. In conjunction with these changes, intake ports are smaller to further increase induction velocity, intake valves are 0.5mm larger for better breathing at all rpm and camshaft profiles have been changed to produce more lift.

Gear ratios for the oil pump have also been changed to reduce mechanical loss, contributing to the engine’s high-revving nature. Several modifications have been made to the middleweight ZX-6RR, including new cams, larger intake valves, a revised intake system, and new gear ratios for the six-speed transmission.
