rocks, mud, hearth, bumps, jumps, holes, slides... &%$#@! my fingers.... Gasss, over reacting, adrenaline, uphills, downhills....I've switched after 45km of dirt, mitas 09 dakar rear is a bit "eated", nice on the light mud ...front Scorpion Rally....good tyre very good grip, nice on light mud. It's true when all say that in front need less weight, overall is a beautiful bike I love it.
