So I’m relatively new to atvs. been riding for about a year with only a couple rides but feel I picked out up pretty well. I’ve been riding my wife’s 2002 trx400ex and I absolutely love that bike. As much as I would rather pay a couple grand for a well maintained used bike is easier on our finances to go through a dealership. I completely fell in love with the 450r tri color, it’s gorgeous. My question would be should I stick to a 400 since I’m still new and it’s what I know(but hate the plastics) or go for the more powerful 450? We do about equal dune riding and trail riding.
