In 2003, there were a number of changes to the ZX-6R, or ZX636 as it is often referred. The engine was fuel injected and engine speed was raised around 500 RPM which resulted in a slight gain in power. Radial-mounted four-piston brakes replaced the previous six-piston brakes and the front forks were now inverted. Chassis improvements resulted in higher rigidity and less weight. An all digital instrument panel was also introduced and a larger ram air inlet moved to the center over the headlight, running through the headstock. The bike, designation B1H, carried over to the 2004 model year with just color scheme changes. The ZX-6RR won the Supersport category award for Masterbike 2004 and placed third overall.PP Tuning performance parts for Ninja ZX-6R/636 (2003–2004).
