i am looking to buy a sport bike, i am turning 16 in a few months and my dad is wanting me to get something so i can ride with him, i have looked at the cbr 600, and the r6 and the kawi ninja 500 and 650, but im not sure, i am on a budget and 2500 is about my max, i have rode dirt bikes all my life and i know how to ride on 2 wheels real well, but im concerned about my height, i am already 6'2 and still growing so i need something i wont be cramped on, i am also 270Ibs... i just want something i can be comfortable on, i know the sports bikes arent very comfortable but i want the most comfortable that i can get.. i appreciate all the responses in advance,,
