Incredibly, the Artrax SX1 motorcycle tire offers both excellent grip off-road and unbeatable control at the track, and does it all at a very reasonable price. Made for Intermediate / Hard terrain. The Artrax SX1 has been developed for use on intermediate to hard terrain and delivers the control for which you are looking. The SX1 tire has ribbed sub-tread between the lugs to add control in soft conditions. Shoulder knobs help you put power down in the turns. The stiff sidewall with 4-ply construction resists punctures and helps absorb shock when going big. Widely spaced knobs help to prevent the tire from getting completely packed with mud and dirt, thus providing great clean-out and excellent bite. Sold individually.
