I bought these ITP XCR tires for the rear of my 2004 Honda 400ex and let me tell you, for desert trail riding, these are great. I had the chance to use them at El Mirage, CA, a place with awesome dirt trails (desert trails) and a huge dry lake bed, and these tires provide EXCELLENT traction, especially in turns. The stock rear tires provided average traction on hard dirt, like the dry lake bed, but on loose dirt they lose traction at times, especially when you punch the throttle. With the ITP XCR's, great traction was always there, even in El Mirage's spots of loose sand, which didn't really surprise me, considering how many knobs these tires have. EXCELLENT DESERT TRAIL TIRES!
