Stephen Clark

Fresh blood to ORC in 2007, Stephen brings a technical background and great action photography skills. A transplant from Scotland, he's now based in Southern Idaho. His locale means he's blessed with easy access to some of the best sledding in the West, and he takes advantage of it as often as he can.

RMSHA racer Trevor Erickson spearheaded the concept and contacted ZBroz Racing to help with the project. Before long Trevor had a Polaris IQ600RR ready to be ridden in the dirt. Black Diamond Extreme also got in on the project and had a Arctic Cat Sno Pro 600 converted.

Our test riders favored the Ski-Doo Summit machines in both 600 and 800 engine sizes over other sleds we rode. Check out the full story of how the 2009 mountain sleds performed.

Getting the chance to ride is the best part of writing any vehicle review for Off-Road.com, so check out what our test riders thought of the latest 600-class sleds.

For 2009 the 600 class is as hot as ever with two new engines from Ski-Doo, chassis updates from Arctic Cat on their F-series, a new Dragon SP from Polaris, and suspension upgrades on the Nytro from Yamaha.

Are you looking for a well-rounded snowmobile that is equally as capable on the trail as it is off-trail in the powder? We look at Arctic Cat, Yamaha, Polaris and Ski-Doo cross-overs, just for you.

We break down the latest mountain-riding, snow-loving offerings from Arctic Cat, Yamaha, Polaris and Ski-Doo.

Technical overview and photos of the new snowmobiles from Ski-Doo, Yamaha, Arctic Cat, and Polaris.

The stock Nytro MTX does not come with a pivoting riser block, so the amount of adjustment is limited. We wanted to rotate the riser forward and back to find the ideal riding position, so a mod was in order.
