Introduces the 2002 Grizzly 660 4X4

Who’s afraid of the big, bad Beast? Take a number.

Folks, if you thought the Grizzly™ had the competition running scared before, well, they’re absolutely petrified now. Because there’s a brand-new Bear in town: the all-new-from-the-mud-up Grizzly 660 Automatic 4x4.

That’s right — 660cc. As in the biggest, baddest engine ever spooned into a utility ATV. It also happens to be the most technically advanced, featuring liquid-cooling and the same patented 5-valve cylinder head technology found on the ultra-sport 660R Raptor.

The innovation doesn’t stop there, either, as the Grizzly 660’s 45° engine layout, tucked into a rigid, lightweight CAD-designed chassis, helps create class-leading ground clearance and a low seat height — which translates to quick, nimble handling and superb comfort for you. Next, fully automatic Ultramatic™ transmission with dual Hi/Lo ranges and reverse takes care of routing the Grizzly’s prodigious powerband to the ground, while On-Command™ 4WD — with an all-new, push-button locking front differential — lets you choose between 2WD and limited-slip or full-time 4WD.

And in what could be perhaps the biggest news of all, this Grizzly boasts fully independent suspension front and rear with more total travel then any ATV in its class.

But we’re just getting warmed up here, so why don’t you scroll down to get a closer look at the Grizzly 660’s list of incredible features. Rest assured, you won’t find a more capable — or better-looking — ATV anywhere on earth.
