This young guy is a force to be reckoned with
Following the release of the ACE line of vehicle from Polaris, some might find building a custom single-seat RZR from scratch to be a little overzealous. Well, not when your son is youth UTV World Champion Casey Sims. Twelve-year-old Sims has been racking up a lot of hardware recently, finishing on the podium in 30 out of 31 races in 2016. For 2017, Sims will be competing in a fully custom single seat Polaris RZR 800 built by Got Sand Performance.
