Jackson "Jacko" Strong, Moore's fellow X Games snowmobile competitor, is auctioning off his 2012 Polaris IQ 600R snowmobile, which he rode in competition at this year's X Games, to help benefit the Moore family.
Strong, a 21-year-old Australian native, also crashed during last week's X Games competition. During his Best Trick snowmobile run, he let go of the handlebars and attempted to grab the back of the sled in a midair stunt, but couldn't get a good grip and flew off. The snowmobile landed on its skis and raced into the crowd watching on the sidelines. No one was seriously injured.
The Moore brothers are decorated Winter X Games veterans. They made their debut in competitive snowmobiling in 2010 in Aspen after years of racing ATVs.
Caleb, who has four Winter X Games medals, took home the bronze medal in Snowmobile Freestyle at last year's games, and stood next to brother Colten on the podium, who had won gold.
