I would run some ITP or DOUGLAS aluminum wheels, But if you are not going to worry about the weight run the hipers. You would want to run american racers size 18x10x10 on a 10x8 wheel. Beadlock wheels are not really needed since you shouldnt run less than 10 lbs of air unless it is extreme conditions at the track.. Also shorten your swingarm 1 1/2" for traction and I would suggest getting some good adjustable aftermarket shocks.. Use your shocks to load 10lbs on the right rear.. The LTR is very heavy compared to a YFZ or a 450R so do whatever you can to lighten your LTR up... You need nerfs, front bumper, sway bar, kill switch, 50" width, 8" numbers with appropriate background just to get started and be legal....
