(CNN) — Snowmobiler Caleb Moore died Thursday, a week after a crash that has raised new safety concerns about the X Games. He was 25 years old.

“He will be truly missed and never forgotten,” his family said in a statement.

“The family wishes to express their deep gratitude for all the prayers and support they have received from all the fans, friends and family around the world that Caleb has inspired.”

Moore, a freestyle snowmobiler, was attempting a backflip at the Winter X Games in Aspen, Colorado, when he couldn’t rotate his machine enough to land properly. The skis dug into the lip of the slope, bringing the 450-pound snowmobile crashing down on him. The vehicle slammed into Moore’s head and chest.
