I've been running an AC Racing Swing arm plate for over a year and its been working great for my '06 YFZ450 . I am a little disappointed in how easily it bends and the welds have broken but its definitely better than getting my brake or sprocket bent up. I've read on this forum some good things about the DG and Pro Armor. My question is, will they hold up any better than my AC Racing? Do you guys have a better suggestion than DG or Pro Armor? Thanks!
