My YZ came with a set installed but my grips were shot so I pulled them off to put new grips on and thought hey..... that looks a bit better. So I let them off. A few days later I was going through stuff and saw the old guards which were Acerbis with a metal frame and plastic covering and noticed how they were beat all to hell. Not neglected and dropped beat, but the furthest side of each guard was skinned up bad Imagining my fingers being there I put them back on ASAP but I did adjust them lower this time so I wouldn't notice them in my way as much.
