Only was Aware of a front locker button  to lock front axle besides  some Polaris models with turf mode for the rear axle.   Anyways all sxs and ATVs I've ever owned had a locked rear axle all time. However I'll definitely keep my eyes open and I learned something new,  thanks.
	
		
			
		
		
	
				
			 
 
		 
 
		 . They do have the option of locking the front differential in worst case scenarios by either pushing a button or turning a knob.    Imo a open differential is more parts to break on a small rear differential.  Solid axles are a bit tougher I believe.  As previously said what I ride definitely doesn't have as tight a turning radius as others with an open rear differential.
