mine has about 250 miles on it and I keep it up really well but like you said the black plastic is all scratched up. The only thing you can do is keep applying the tire foam to it. Personally I buy wd 40 by the cases and thats what i use after every ride on the whole bike except the yellow and it keeps it up pretty well.
I have heard people will spray WD-40, RemOil, or babyoil under the fender wells so mud/dirt will slide off. Anybody do this?
I know my plastic is gonna scratch up. I am glad I chose the yellow. Really, the black is the only plastic that is scratched up. And I am happy I didn't go with a black Rincon like my uncle. Two trips and that atv looked like it was 5 years old. Amazing.
