Provides all the benefits of radial tire technology-super-comfortable ride and exceptional traction over a wide variety of terrain conditions-but with a hard-core sporting edge. Very light in weight yet 6-ply tough to inspire greater rider confidence. Unique Z-shaped tread pattern and natural rubber compound deliver exceptional performance and extended tire life. Front Trac Star rides like an OEM tire but steers like an MX racing-type tire, for excellent ride comfort and precise control. Rear Trac Star's staggered tread pattern provides a perfect balance of traction and control that enables it to hold a line as well as slide predictably. Wide spacing between knobs makes this one of the best self-cleaning tires on the market-ideal for muddy conditions. Significant improvement in cornering and overall handling compared to OEM tires. Front: 21/7R10, 22/7R10, 23/7R10; Rear: 20/10R9, 20/10R10, 22/11R9, 22/11R10 (6-ply).
