Went to an awesome place in PA with my new quad. Check it out!

 

Lotsa fun.

 

Goes pretty well with the stock tires. I'm sure you're already looking at some upgrades though. With more aggressive tires like Maxxis Zillas or something like that, you're going to have more fun in the mud.

 

Were you using the Diff lock some times? Get some 27" Maxxis Zilla's when your tires wear out.

 

Didnt use the diff lock there. I really want bigger tires, they will be coming soon.

 

Diff lock makes a big difference. This video shows the difference , the guy tries twice in normal 4x4 (one front wheel turning) then he puts it in diff lock on 3rd try and the two front wheels turning at once makes the difference.
He breaks his rear right tire bead so it looks like only one rear tire is turning.

 

Diff lock is nice to have when you need it. On older non-eps models, it makes steering really difficult. On an eps equipped model like the new King Quad, it should still be pretty manageable.

 

The steering is much harder while in diff lock but diff lock is only used in slow speeds and for a short section that 3wd just will not cut it.
Like the above video , once that guy got over that nasty rut bump you can bet he returned it to normal 4x4 very quickly. You have to stop a ATV to engage diff lock but you can disengage diff lock on the fly.
Nobody is going for a exstended ride with diff lock engaged EPS or not.
