Does anyone have the Kimpex Rear bumper on their Foreman 500? I'm debating between the Kimpex and the Bison. I haven't really found any reviews on the Bison, so I don't know if I should go with that or not. I've read a lot of good things about the Kimpex. If anyone has a Kimpex please give me some info, and pics if available. I was going to get a front bumper also, but don't really see the need, I'm leaning more toward the bash guard from aluminum products. I don't like the looks of putting another bumper over the existing bumper. I can't find a replacement front bumper. Any input will be appreciated!
