Ive ridden the older ninja and the new ninja and i still would rather have my Hyosung. I know most people on here may not like the Hyo but the damn bike has a 110mm front tire(mine is a 120mm) and 150mm rear tire. Thats almost as big as 600cc bike tires. The damn thing has a huge footprint for a 250. Here are the specs for the two bikes and by the numbers the Hyo takes the cake. More Horsepower, Larger rear tire, Larger front forks, and Bigger brake rotors. The V-Twin is set at a 75 degree angle to maximize power without having to have 14k+ RPMs(10,500 redline) . Now the Ninja does lead in seat height by 1/2" and it has .25gal larger tank. However the Hyo gets 60-80mpg and the ninja only gets 50-65mpg so the Hyo has a much longer range. Now you look for yourself. Some of the things in the Ninja page need to be converted from metric but ive done some of it for you.
