I do not see this rig being a big hill climbing machine. Way to high of a gear on the bottom end. However with that being said, I did witness this machine in a short course/moto cross course in a legitimate race. OMG that son of gun willl move and corner like its on roller coaster rails and lost to a 1000 turbo in a corner from over correcting and caught back up VERY quickly and he had another lap he would have smoked that turbo. Now on the second heat a stock 900S RZR chewed his ass the entire time.
