Kawasaki Ninja ZX-6RR Service Manual (2005–2006)

Kawasaki created the ZX-6RR as the race-homologation side of its middleweight Ninja supersport program. The model first appeared for 2003 alongside the ZX-6R; Kawasaki’s official 2003 INTERMOT announcement described the RR as a machine built specifically for Supersport-racing applications, with exclusive track-oriented features and a back-torque limiter. That role distinguished it from the larger-displacement ZX-6R street model and tied the RR directly to production-based 600 cc racing rules.

For 2005 Kawasaki introduced another new Ninja ZX-6RR generation at INTERMOT, saying the ZX-6R and ZX-6RR had been developed for top circuit performance. The 2005 model announcement placed the RR at the sharp end of Kawasaki’s Supersport range. The catalog taxonomy labels this model ZX6RR; in factory literature the motorcycle is styled Ninja ZX-6RR. In the manual’s specification, the 2005–2006 platform uses a 599 cc liquid-cooled DOHC inline-four with a 67.0 × 42.5 mm bore and stroke, 13.9:1 compression and high-rpm tuning, making it a 599 cc supersport homologation motorcycle rather than the 636 cc street-focused sibling.

The engine is paired with dual-stage digital fuel injection: four Keihin TTK38 primary throttle bodies and a second bank of multihole injectors. Drive goes through a wet multi-disc clutch and six-speed constant-mesh gearbox to a chain final drive. The chassis specification centers on a tubular diamond frame, inverted front fork, Uni-Trak rear suspension, dual front discs and 17-inch wheels. These details reflect the RR’s narrow brief: a compact production platform intended to translate race-developed geometry, braking and high-rpm engine performance into a road-legal homologation model.

The factory application codes in this publication separate the two covered years as ZX600-N1 for 2005 and ZX600N6F for 2006. Kawasaki’s current Owner Center independently identifies the 2005 Ninja ZX-6RR as ZX600-N1 and the 2006 model as ZX600N6F. For 2007, Kawasaki moved its middleweight supersport program into an all-new ZX-6R generation, which the company described as a complete model change aimed at top-level circuit performance.

This download is specifically factory service manual 99924-1346-03, Third Edition dated December 1, 2005. Its Model Application table explicitly lists 2005 ZX600-N1 and 2006 ZX600N6F, so the existing 2005–2006 range is retained and now factory-verified.
