Best Honda Sport quad For The Desert

Hi everybody, long time reader, first time writer.

I’m 23 years old, currently live in Florida and ride a 400ex that I race every now and then when I have the time. I’ll be moving out West to Southern California this Fall and I’d like continue racing, only I’d like to try my hat in the Desert and see what I can do.

So that leads me to my question. Will the 400ex, with a few modifications of course be able to keep up in a "open" class were there is no cc limit or will I have to sell it and start over with a 450 if I want to be competitive? Let me know what you guys think and thanks for allowing me into the forum.:icon_ peace:
