Snow bike conversion kit takes motocross into the backcountry

While most people would never think to strap a ski to the front of a motocross bike, Reagan Sieg has a bigger imagination—and even bigger cojones.

Sieg is a pro freestyle motocross and off-road rider who grew up on bikes and sleds in the mountains of British Columbia. The snow bike in this clip is a 2015 KTM 450 SX, which he bolts onto a Timbersled SX snow bike conversion kit. A standard kit with fitting costs $5,600.

“Riding a snow bike provides the same enjoyment as snowmobiling, but with its own unique characteristics because a bike can go places a sled cannot,” Sieg told GrindTV. “Sleds are much heavier and have a planted ski stance, meaning you need both strength and experience to make them sidehill and perform off-camber turns. Snow bikes are about 200 pounds lighter than a sled and much more maneuverable.”
