Good video. That's much quicker to engage than previous years. My son's 2009 isn't quite as fast to engage as the 2010 in the video. I find it a little "jerky" for lack of a better term, but he hasn't failed to get through anything I have. Just takes a little getting used to.

 

That's much better than all the other videos I've seen. I think I could live with that.

P.S. Most people don't know it but Polaris tried a Visco-Lok once, but it was only on one model, the 500 Magnum RMK, and I think it was only the 2002 model year. I've seen exactly one of them and that was at the dealer.

 

the only problem I have with that video is you don't know if it's the other 3 tires pushing the 4th tire over the stop, or if there's actually torque coming through the 4th (front left) tire pulling it over the stop.

you see the front right tire spinning faster, but that does not mean the left front is not partially engaged (like a clutch) and pulling also.

 

Watch the video again, the right tire, and both rear tires are on rollers, the front left is the only wheel doing the work.

 

 

defiantly better than they use to be. Id still wanna see it in a real situation. The reason i say this is b/c all the other tires do not have resistance on them. Picture it if the were on dirt or solid rock. Is this wheel kicking in so much quicker b/c of very little resistance? just a thought.

 

All the diff lock ATVs are true AWD . The only thing I do not like about them vs the Polaris system is you have more steps to do.

Your have to stop put the ATV in low Range engage the diff lock, once through the trouble spot stop again and put the ATV back into 3wd or 2wd.

The Polaris system is 2wd or AWD with no in between. The ATV does it on its own not the rider with no reason to stop.

 

Personally I prefer the 4-wd that CanAm uses.

I would love to see a real life situation where a little tiny bit of slippage from the viscous coupler really made a huge difference or kept the CanAm from making it up a hill or out of a mud hole or even while rock climbing.

Other than Polaris and CanAm you have to hold a lever or something and usually when the front diff is locked it will be governed in some other way like speed or rpm.

The problem with Polaris is that it reverts back to 2-wd when it's not needed and when I put something in 4-wd I want it in 4-wd. It should be my choilce not the machines.

The 4-wd on the Polaris has to meet certain criteria to engage, rear wheels slips and the RPMs have to drop below 3100 rpm after 4-wd has been selected before the 4-wd will engage.

So if I'm riding down a road and switch the 4-wd on and power thru a corner all I'm going to have is 2-wd unless I allow the rpms to drop below 3100 rpm first.

Polaris 4-wd works after you have met all the requirements, just like the ADC - only works in certain conditions.

I'll take CanAms 4-wd over the others anyday of the week.

 

It really comes down to a matter of preference. I can deal with all the systems out there pretty well. My only real complaint is with Honda. I've seen places where the extra little bit of traction makes the difference between climbing the snow covered bank or just walking right up it. Same goes for rocky hill climbs and deep mud. I think the issue of hard steering with the wheels all locked together has been mitigated by everyone now offering power steering. Again, personally, I like the Polaris system just a bit better than the older (2009 and older) Can-Ams. Something as simple as loading quads on a frost covered tilt trailer has shown me that an already locked or essentially seamless locking mechanism is better than gradually engaging. I'm glad Can-Am has gone to a quicker engagement. It shows they are listening to the buyers.

 

I agreed , Diff lockers only works in low range because the steering is almost uncontrollable its a safety thing.

For the Polaris method.

If the rear wheels are not slipping at all why would you want to be in 4wd? A ATV steers easier in 2wd.

Who would want to engage 4wd while doing power slide corners?

The Can Am system is my next choice, buts it,s not as instant,and once I,m through a troubled spot on the trail I want the ATV to go back into 2wd not 4wd .
