Let's face it, an advert put out by a manufacturer will be as biased as possible, so those kinds of videos really aren't worth much IMO.

However I can vouch for the Grizzly's drive belt. I have attached my quad (my 660 Grizzly) to logs so big that all I could do was spin all 4 tires. So what did I do then? No, I didn't cut the log and make it smaller, instead I backed up to put some slack in the chain, then hit the trottle and hung on. If it didn't go the first time but showed signs of moving, then I'd repeat that process until I got it going (within reason of course). The only thing I've ever done with that treatment is break my stock hitch (twice, the 2nd time after reinforcing it). After the 2nd time I made my own hitch tongue out of a regular truck hitch and fastened it to the frame with larger than stock grade 8 bolts. Now the hitch doesn't break any more! So that is the kind of treatment that my 660 gets (when I wasn't blasting down the trails with it). It is still on the original drive belt too and the machine is going on 6 years old. Of course this is severe machine abuse and chances of breaking something is probably high, no matter what machine you are using. It's just that so far the Grizz has held together. I probably should follow this with a statement like "don't try this at home".

As long as I have the 660, I will not abuse the 700 like this. I just use it as a trail rider (slow, technical, fast and hard, and everything in between)...

 

what is the boiling gas thing you all were talking about? on the older grizz?
