Malmborg Pilots First 4-Stroke Over the Top at Jackson Hole

Yamaha has had a resurgence in cross-country snowmobile racing this season and the effect seems to be rubbing off on the hillclimb racers as well. Kody Malmborg, Jr. did what many doubters thought was impossible on Sat., Mar. 24 – top the Snow King on a four-stroke snowmobile at the Jackson Hole World Championship Hillclimb put on by the Jackson Hole Snow Devils.

Malmborg piloted his Yamaha FX Nytro MTX to the top of the steep course as the first four-stroke to do so in the 37 years the event has been held – while also becoming the first Yamaha to qualify for the Pro finals since 2001.

The Jackson Hole World Championships are, as one observer put it, the Daytona of snowmobile events, and the mountain course practically defies description. It presents itself as a nearly vertical face of about a half-mile in length, with 28 gates that the machines and drivers have to negotiate on the way up. Favoring immense horsepower, traction, responsive handling and of course major riding talent, the course quickly weeds out all but the best. “It’s basically like driving up a skyscraper,” says Yamaha snowmobile marketing manager Wade West.

Friday was reserved for Semi Pro finals and Stock qualifying – with Saturday scheduled for the big-horsepower modified and Pro sleds like Malmborg’s FX Nytro, and Sunday reserved for the Pro finals. Even with the FX Nytro’s extreme horsepower and torque, the conditions were so challenging that Malmborg was making it just past halfway up during most of the classes he had entered. The breakthrough came on Saturday afternoon, during qualifying for the Mod 700 Pro event.

“The course conditions on the bottom half were slushy, and the top was really icy with rocks and stumps, five-foot ruts and six-foot trenches,” says Malmborb. “When I left the gate everything felt great, and I just told myself to stay calm and work through every gate, look ahead and pick my lines, use the trenches to my advantage and carry my momentum. I was definitely exited to make it over the top of one of the most challenging hills anywhere. There was definitely some hollering going on!”

In Sunday’s Pro finale, Malmborg finished eighth among the world’s 25 top hillclimbers after encountering a few problems on his way up the course. But his achievements on Saturday had already made history for Yamaha, for four-stroke snowmobiles, and for Malmborg’s newfound career in hillclimbing.

“Our goal was just to get one sled over the top at Jackson Hole, and we are elated to be the first four-stroke in history and the first Yamaha team to do it since 2001,” says Yamaha’s Eric Josephsen. “Doing it on our first try makes it even more incredible, and I really want to thank our crew chief ‘Big Kody’ Malmborg for working so hard to make it happen. I’ve always said that the FX Nytro can do everything that a two-stroke sled can do and today we proved it.”
