The only fast quad honda ever made was the 250r,with slight mods of course. The 400ex is good for wheelies and going slow,the 450r is just the same with about 10 more HP. Anyone that says an equally moded 450r will beat a Banshee lives in ther own little honda world. And to the guy that said a 400ex will beat a banshee is on crack. A 400ex is not much quicker than a piped Warrior.
