The grizzly will rip a vinson a part in the mud,snow,and speed. A vinson will just get hung up in the ruts it doesn't have that much g/c also driff lock does help out some. The only thing the vinson will hang for is fast trail riding because you go to watch some with the grizzly they are a tad bit top heavy.

 

no comparision the grizzly is no match agaisnt the vinson on any kind of speed mannuever or tough trail riding. if two pros raced each the vinson would win, irs is for slow trail riding and farm work,the swingarm is for aggressive riding and sports bikes.with large mud tires on the grizzly it makes it all the more tippy.the grizzly can beat the vinson in a straight race on pavement. it may also be better in the mud if thats what you like doing,but the vinson is great in the slop too if equipped with a winch you,ll never get stuck. i was thinking about getting a grizzly before i bought my vinson .but after doing a lot of research i learned allmost everyone who owns a grizzly has rolled it due to its tippy feel and top heavy frame
