I built a 12 inch front wheel to try racing at a local kart track. I didn't like it so I swaped back over to dirt wheels. Its a 12x1.6 Black wheel with Bucanan HD spokes laced to a stock KLX hub. Wheel was only used for a few races. Comes with bearings and everything needed for the swap. Buy two 12" tires and your ready for motard. Cost me around 300 to build, PM me with a reasonable offer. I accept paypal and money orders.
