Progress! Rear end has come together. Lone Star Racing +2" round house swinger with carrier in silver metallic RPM Dominator II +7" axle Duncan Racing stainless axle locknut New OEM brake and sprocket hubs New OEM caliper Speedlinez stainless brake line DP stainless rotor SunStar steel 40 tooth sprocket TM Designworks chain roller kit Maxxis Razer 2 20x11-9s This bike came with stock axle hubs with brand new 6 paddle Skat Trak Haulers mounted on 8" aluminum rims. I do have lots of sand to ride in nearby, but have access to plenty of dirt as well. I noticed that wheel size was pretty limited on those stock hubs (WTH Yamaha, 110? why?) so I opted to buy a set of Raptor hubs with the 115mm bolt pattern. Bought the tires mounted on ITP 9" rims.
