I have a set of Acerbis plastics on my 04 KX250 that I am not really pleased with. They are really thin and flimsy compared to OEM ones I took off, and they also fit poorly. I never put the new rear side panels on because they do not fit. I had to trim the OEM ones a little so they would work with the Acerbis rear fender. They are also crooked on the bike...the front and rear fender are not molded straight. So, it is unlikely I will ever get another set of Acerbis and I have had poor luck with their other stuff as well. On my DRZ I got a mount kit for my handguards and it was drilled by hand it looked like. The holes were anything but centered so it looked and worked like crap. Needless to say it is sitting on a shelf now. My question is this - do any of the aftermarket plastics compare to OEM? They are thick and rigid which is good. They might weigh a few ounces more but that is OK with me. The OEM plastic is really expensive so if another company makes a good product I would give the a try first. What to you guys like? UFO, Cycra, Polisport, OEM, etc ?
