Kawasaki’s site features details on the 2008 Ninja ZX-10R.
According to Kawasaki…
Engineers aimed for an ideal superbike with engine and chassis performance capable of satisfying professional racers, combined with top-notch streetbike qualities for mainstream riders. It’s a delicate balance, but these aren’t your average engineers. They’ve been directly involved in the development of every 600 and 1000cc supersport machine since the 2003 Ninja ZX-6R, plus Kawasaki’s factory Superbike racing efforts, so they have the know-how to deliver the goods.
The result is an exceptionally communicative machine that provides the clean two-way rider and machine dialog demanded by professional racers. Placing the ZX-10R in the racing crucible and applying lessons from that unforgiving environment resulted in an ideal balance to satisfy the most demanding of riders.
