I am just wondering if there is a big difference between a kx 125, kx 250, and a kx 500. Like if the 250 is alot faster than the 125, and if the 500 is alot faster than both. I am kind of new to dirtbikes, and have only ridden my Kx 125 for like 2 minutes and then it broke. Its gettin fixed and i can't wait to get it back Thanks
