There's no such thing as a 'Suzuki Ninja' 'Ninja' is the trademarked name of a series of Kawasaki's sport bikes, Suzuki's sport bikes trademarked name is 'GSXR' e.g. A Kawasaki ZX-10R would be similar to a Suzuki GSXR-1000, there are a lot of different things on each bike but a lot of Suzuki and Kawasaki parts are interchangeable on various bikes.

Aprilia, BMW, CCM, Cobra, Ducati, Gas Gas, Honda, Husaberg, Husqvarna, Kawasaki, KTM, Polini, Suzuki, TM Racing, Vertemati, VOR, Yamaha that are all active dirt bike manufacturers. There are also numerous companies that no longer manufacture dirt bikes.
Sport bikes are not made for tall people but there are two bikes that are bigger than your 600cc and 1000cc bikes. One is the Suzuki 1300 Hayabusa and the other is the Kawasaki 1400 Ninja. I am 6'5 and have owned both but the Kawasaki fits me better and is superior to the Suzuki if it is 2012 or newer.
