In my opinion, I believe that the Suzuki GSX-R1000 (2013-2019) is the best vehicle for you based on your height of 6.4 inches. The GSX-R1000 is a great all-around sports bike that rides well, performs well, and handles well. Because it is light and nimble, it is an excellent choice for navigating corners and tight roads. While the Ninja ZX-10R is an excellent bike, it is a little too tall for you and would be slightly more challenging to ride.
