I am going to be getting a new quad in the near future and I just wanted to know what you guys thought. I have narrowed it down between a 250r (whatever one I get will have a 310/330 big bore) or a custom 426 quad. I will be riding all mx, but I don't know which to get. I know the 426 will be more expensive, but will it be faster than a 330? I am leaning towards the four stroke because it should be more reliable and I won't have to get it rebuilt. What should I do?
