Here is a video of a XP and maverick trying the same hill's minutes from each other. The XP does have 2 riders and the maverick does have better tires (both bighorns, mavericks are brand new though) . But even with that said in these conditions (muddy, wet) the maverick had alot more low end and was able to really jump up on the climbs and it also seemed like the suspension was better to bomb into the climbs. Now on a dry day when the XP's are going vertical on stupid stupid climbs, will the maverick be able to do just as good, that I dont know. Both are great machines though.
