Kurt Busch Shares Childhood Memories in First Post Since Brother Kyle’s Death

Kurt Busch focused on happy childhood memories as he shared his first social media post since the death of his younger brother, fellow NASCAR driver Kyle Busch.

"Finding a silver lining, I reflect back on the days Kyle and I raced anything we could get our hands on," he wrote in an emotional tribute. "From big wheels to competing on the biggest stages in motorsports, we were more than just fierce competitors."

"We pushed each other, challenged each other and learned from each other," Kurt added.

Kurt shared several photos of himself and his late brother together, including a childhood shot of them driving a kid-sized racing vehicle with Kyle sitting in Kurt's lap.

More recent shots show them on bigger stages, driving in NASCAR's premiere series races and holding up trophies together.

"Kyle, your passion, determination and love for your family inspired everyone who knew you," Kurt continued. "No trophy,  championship or accomplishment could ever measure the impact you had on my life and on so many others."

"I will forever be grateful for the memories we made, the lessons you taught me, and the brotherhood we shared," he added. "My heart is broken but I know your spirit will always ride with me."
