First of all I am a very heavy set guy (295lbs and 6'4") so I know I need a bigger quad. I am thinking of the Honda 450r or the 400ex. The 400 is considerably cheaper, however is it worth it to upgrade to the 450r? What other bikes would you guys consider for a man of my stature? Thanks. Edit: Forgot to say what I would be doing Anyways, there are some trails up here and some at Hungry Valley, but I would mostly be using it for the dunes at Pismo or at Glamis.
