I think it is time to upgrade, or maybe not. I have a 2004 drz400e and just love it. I am 45 yo and started riding again when I bought my Suk, when not riding since I was 15 yo and that was limited riding. SO, I have gotten to the point that I either need to upgrade to either klx450f, or wr450f or even that RED bike, or spend money on the Suk to get her up to my level. The bike is currenty stock with only some carb work done for air box opening and did some stock silencer modifications. Where is the money spent the best and still have a reliable bike which I have had since I bought the Suk. I am just so confused and not sure what would be best for me. I know only I know what is best for me but I am looking for a little help.
