I've never driven such a powerful machine like that and it doesn't break. I feel like i'm on a sled with this thing except not quite as powerful of course, but in the Sport/Utility ATV industry this thing is the one with the big KAHUNA'S. Ya i hear that HO rocks too but its still 700+ pounds so that takes alot of the agility feeling away, i pull the front end right off the ground in dirt with the Grizz and on take off you feel like your on a small rocket especially near some slower machines. Oh ya and i've never had it Over Heat.
If anyone is wondering if the Grizzly is the beast i can say from experience it is,
Low maintenance
durable
powerful
fun
and fast.
Little hard on fuel but hey look what you have, 600CC's of pure MANLY power like 4wheelatv mag. said.
I hope to have it for 10 years without any major problems, like i did with my old BIG BEAR.

Might I add, Its not that bad on fuel, I seem to get about the same milage as the sp500's and better than the new HO's!!!

And YES GRIZZLY'S ROCK!!!!
