Kyle Busch's iconic celebration has been performed in tribute time and time again since his sudden passing in May, but this one is undoubtedly the most heartwrenching of them all.

Kyle's 11-year-old son, Brexton, won his first race since his father's passing in the Non-Wing Nationals at Port City Raceway in Tulsa, Oklahoma, this weekend, performing Kyle's signature bow in front of the applauding crowd in a touching tribute and celebration.

Brexton had started his A-Main in 14th on the night, but eventually ran out as the winner in the Restrictor Micro class, powering his way through the field to take the black and white checkered flag.

Elsewhere on the night in Oklahoma, Brexton also won one of the heat races in the Non-Wing Micro class and finished sixth in the A-Feature of that class.

Busch family reacts to emotional Brexton win

"My first win since my dad passed. I don’t like to talk about it much, but the last two months have been really tough," Brexton wrote on X after the win.

"I’m missing my crew chief, my driver coach, my dad, the guy who I looked up to more anyone.

"I know he would be proud the way I ran the top (much better than him lol) to win my first Micro A-Main at Port City. We love and miss you so much dad."

Mom Samantha also posted an emotional message following Brexton's victory, writing on her Instagram story: "First win since losing Kyle. I've never felt so proud and so heartbroken at the same time.

"Brexton continues to amaze me with his determination, his resilience, the way he keeps showing up to do what he loves even while carrying so much at such a young age.

"Watching him celebrate, all I could think about was Kyle. There was nothing that made him happier than watching Brex race, spending the day tinkering on his car and then being the first one sprinting to Victory Lane with that huge grin on his face."
