I guess you do get what you pay for.. These were advertised as real Acerbis hand guards at a great price. But after receiving them I noticed that they appear to be knock offs. Real Acerbis guards have their name silkscreened on, these had peel and stick letters. Also, they were not in an original package, just loose in a box. I'm afraid that I was tricked on these, but on a good note they seem to be decent quality, only time will tell.
These fit like a glove on my YZ250 with Pro-Taper 7/8" bars. The install was quick and easy, a 5 min adjustment and I was off. They offer clearance of my controls and keep branches from hitting my hands, clutch and brake on the single track.
I didn't have any trouble installing them and they look great. I have not crashed with them yet but they look solid. I don't think I'll have any trouble with them.
