ok so i measured it out today...with the YFZ longtravel arms the banshee's over all width would be 49.8" wide...
a factory 2010 YFZ 450R is 48.8" wide
if you thing of it the banshee with YFZ LT arms isnt outragous..only 1" wider than a yfz 450R
the only down side (by my calculations) is that one would have to run shock which measure some 20" long!!!! thats a serious shock..
