Default Can Am Visco Lok

The can am is not a cheap 4wd system it works like twisting a rubber band until you cant twist anymore, more wheel spin causes the tire with less traction to gain more grip until it is locked together. it is a hydraulic type system like is used on some high dollar awd cars, it seem to work well in all conditions. The Polaris on the other hand when you flip the switch it locks all wheels together after the rear wheels spin a bit, i think this is better because you dont have to wait for the other front wheel to "catch up". polaris should in no way be compared to the other 3wd atvs out there because it is an actual "awd" system. can am still has a good system though.

Actually, ViscoLok is one of the few things that Bombardier has actually done right. Aside from using rotax engines.

Yamaha, Honda, Polaris; they use what is called 3 and a half wheel drive. This is because as you know at the rear axle, there really is no differential. Its a solid axle. There is also no differential in the transfer case. At the front axle of these manufacturers they actually keep one of the wheels geared right to rear axle, and the other wheel is provided a limited slip engagement. Frankly, thats junk.

Bombardier on the other hand, actually has a differential in the front and in it is a wet disc brake. It really works slick, I have one on my Bombardier Quest 650. It works just like a regular differential till the wheels start spinning to fast and then wammo, it locks up! Done by hand you don't notice the typical wet disc operation. It locks up tight and smooth. But on the trail, scampering up steep river banks it will sometimes make the dreaded noise that all wet disc brakes make. It's not damaging in any way, but leaves you worried. Just something you don't normally hear while on an ATV.

It works just as they claim. this actually makes the thing steer easier, too. The only thing that would make it absolutely perfect would be if they had equipped the rear with the same thing. That would have been truly awesome. I was totally impressed by it even though I don't like 'Can-am'
smoke some sheeet? dude Polaris makes one of the best 4X4 systems availible.
and its true un demand 4X4 fully locked. no 3 wheel drive here....

and the bomb design is almost the same.


bah ppl should learn stuff befor they comment on it.......

The single brake lever is totally wrong... there is so many situations there you might only want to use the rear or front brakes! Does anyone know if the Renegade is gonna be the same?

I usually ride like my hair is on fire so I cannot coolly and calmly lift one wheel in the air and observe how far the wheel travels.

On another forum though, video shows, and riders in the video agree, that viscolok takes about 3 seconds to engage from stopped when doing some serious rock crawling.

What about the video of the guy doing a "reverse wheelie" on an 800 Outlander, no wheel spining there..

I have done a lot of extreme trail running and rock crawling on my Outlander and never had a problem waiting for full lock up. The front lock up seemed seamless to me, but I was always riding aggressively and kept moving.

My point was that the Polaris involves the the whole driveline and works with mechanical clutches as I understand while the VL works with a fluid pressure system. In any case I had no use for the Polaris AWD system. One test ride on one was enough to know it wasn't for me. It rode great on flat ground and had snappy power. Rode like a Cadillac in fact. I got the thing on hills and had a heck of time with it. It skidded and chattered as the wheels lacked up and the machine skidded all over. The back end wanted to swap with the front. It was very unnerving and the pucker factor needle was pegging in the red. I almost dumped the thing. It was making a horrible noise with all of the clanking and chattering and skidding and I thought I'd broken the thing. I got to the bottom and rode up to the buddy I had borrowed it from and apologized to him and felt terrible that I'd trashed his brand new ATV. I was more than a little perplexed when he told me this was how it was suppose to act when descending hills. I rode it around a little more that day but there is no way I could get use to it. It was was even exhibiting this behavior when going down a steep gravel driveway.

The Outlander negotiated those same hills without really a second though from me other than to shift my weight back and to make really really sure not to wreck an ATV that wasn't mine. None of that sliding and chattering. The engine braking on the Outlander is really good. The single brake lever is a pain in the butt though.

Someone PLEASE tell me there is a kit or something you can get to modify the Outlander for normal front and rear brakes. I was constantly grabbing for a brake handle that wasn't there. That and if anyone in the Can-Am engineering department is reading this please go slap whoever was responsible for saddling the outy with a single brake lever. Slap them repeatedly and thoroughly. Then make them design a factory retrofit kit.

The rear chatter is the only thing i can say i dont like about the polaris, you are right it will make you think you have broken something when you go down a steep hill. the outlander on the other hand has a much smoother engine braking and i have never heard it make that scary noise. i dont think anyone makes a conversion kit to change the brakes to a dual lever set up on the can am.

Smoke some sheet eh? I'd have to say I'd lean that more to you. Go grab a picture of your favorite Polaris ATV and 'take it home' with you. I think people like you who have to make a drama scene out of everything belong on the short bus. I don't care WHO makes an ATV because I care about riding them. I've ridden them all, too, probably just like you. I can't say I get particularly excited over one manufacturer unless they come out with something unique. All I can really focus on is the bad things about them because of what I have to fix. Bombardier has been a big dissapointment when it comes to price, availability, and customer relations.

In 2003, when my machine was made, the visco lock system was pretty new, and doesn't require any input from the rider when it activates. My Quest IS an AWD, not just a selectable 4 wheel drive. That is, you can't take it out of 4 wheel drive. We weren't talking about the 4 wheel drive selection system anyways, we where talking about the front diff. I had assumed the unit was some sort of wet disc operated unit, because of a sound I've heard twice while climbing hills that required hard front engadgement. Now thinking on it, it could have been the belt slipping in the tranny. Funny, it sounds just like a wet disc with fat tires on it. Furthermore, there was a post on the net, something about how the unit operates. I had to check it out, as my online manual (which is sposed to have all the details) doesn't show the diff in an exploded view. That article included some information about it being a wet disc type. Although, granted a pathetic victory for you, I can't be absolutely sur.

Mine does turn, some without an absolute immediate lock. As I said, after I hung my quad off the rafters to check the brakes, we played with it a while to see how it works. It will spin like a differential, but the harder you spin it (or it might be revolutions), it will lock up. My dad kicked a wheel to see what happens when it spins faster but it was an immediate lock. I turned it by hand, slowly, and got about a turn and a half out of it before it locked completely. When its locked, though, its locked. Some people have suggested it will still slip when engadged but it wont, maybe if its worn out. My neighbor and I used my quest to push a 78 chev blazer. He thought the driveshaft was out of it, it wasn't. In 4 low, it spun all 4 wheels on asphalt, much to my chagrine. If it can hold a lock on asphalt and spin the tires, it won't have a problem keeping them locked offroad.

ok, what does it have to do with polaris being 3.5 wheel drive like you said?

it works just like a 4x4 truck, hydrolic hubs that lock out when they sence the rear end spinning.
