Ageed.I agree DK35vince - the utility machines stick within the design spec for the belt system with room to spare.
All the sport machines get run hard BUT the Can-Am and Polaris seem to favor the high HP which I believe is part of the problem. This is where the belts become the weak spot and cause issues. All brands have people running larger tires, and even portals so that normally is not the whole problem. I run 4" larger tires on our one Honda and it caused zero issues. Why, because the machine is not run hard and Honda over designed the parts to allow for larger tires (they knew most people oversize the tires).
Portals normally reduce the gear ratio so that does help offset the larger tires being used on those machines to some extent. Well within reason that it. Generally speaking, Yamaha and Kawasaki have a slightly better-designed and more durable belt/clutch system. Honda skipped the belt and went with a duel clutch and gear system. It still has some quirks but overall is a solid design.
Anytime you design an off-road vehicle and sell it, you need to account for the "idiot factor" - you know that guy, the one that uses it as a submarine or low-flying aircraft. Some companies account for the "idiot factor" a little better than others. All the machines are fine if used within their design specs, but when they get pushed is when the weakness starts to quickly show.
I have 10,700 miles on my RZR 900s.
Never had a belt issue, but I have replaced the belt a couple times just for piece of mind.
The belts I replaced still looked really good with around 4500 miles. (I carry them for spare).
But my wife and I ride to have fun and enjoy the scenery, not to see how far we can jump and how deep of mudhole we dive into.
