This may be a dumb question but...............

Could someone explain the difference?

Thanks.

 

A concentric circle is a circle that shares its center with another. Not sure how this applies to atvs though. Maybe you could look at the wheels and tires.

The wheel, and tire are concentric.

 

Anyone???????

 

I'm assuming you're asking about the swing-arm pivot point on the machines such as the Scrambler...

Concentric = The pivot point for the swing-arm pivots along the same axis as the center of the front sprocket. When the swing-arm swings up the chain doesn't get tighter.

Non-Concentric = Such as the Predator, the center of the front sprocket is set forward of the swing-arm pivot point. When the swing-arm swings up the chain gets tighter. That's why you need a certain amount of slack in the chain, so you don't load up the chain when you land a jump.

I own both, they both require chain adjustment. Chains wear-out... I don't see a big enough difference to like one over the other. Adjusting the chain on the polaris products is really easy too.

 

Thanks 2mnytoyz!

A friend of mine was ordering a chian tensioner and asked me what the difference was. I told him that my bike said concentric drive on it and that is why I got the one I did. I just didn't know what it meant.

 

well also the axles are different, because the caliper and brake disk sit on the axle, instead of it being where the swingarm bolts on to, and also i belive the transmition is different ... Austin
