I'm new to DS and bought a 2001 XR650L. It already has the "dave mods" but it needs some new tires. For the rear, how would the Kenda K760 Trakmaster II do for 60% to 70% dirt? The off-road riding includes everything from dirt & gravel roads to single track with rocks. Always some mud in the low sections, but usually it's dry and hardpack. Thanks!
