The best Hard Enduro racers in the world will face off at the 2025 Red Bull Tennessee Knockout (TKO) at the Trials Training Center on August 8-10 – 12 of the 14 previous race winners in it to win it.

The three-day TKO 2025 stands apart fromteh Hard Enduro World Championship again this year and will not feature the head-to-head races in Downtown Nashville.

Racing kicks off during Friday at the Trials Training Center with amateur Hot Laps to set Saturday’s start order. Saturday features two amateur rounds, with up to 30 riders advancing to Sunday’s pro race. Pros start with a Hot Lap Saturday, followed by three rounds and a multi-lap main event on Sunday.

Pro rider pedigree

The 15th annual TKO will fittingly see 12 of the 14 race winners in that time still among the top contenders for the 2025 edition.

Cody Webb won six consecutive TKO’s from 2013 to 2018. The American won an AMA Trials championship before converting to Hard Enduro and EnduroCross racing and he has earned several championships along the way. With a win and several podium finishes in the 2025 AMA US Hard Enduro series, he is still a threat to take TKO win number seven this year riding the Yamaha YZ-F four-stroke.

Trystan Hart is a three-time winner of TKO. The Red Bull KTM racing rider is also a four-time AMA US Hard Enduro Champion and two-time AMA EnduroCross champion. He is one of the few riders to beat Mani Lettenbichler heads up at a Hard Enduro event and he was angry about finishing second last year. He will be aiming for TKO win number four.

Mani Lettenbichler is the most decorated Hard Enduro racer in the world. The Red Bull KTM factory rider is a multi-time FIM Hard Enduro championship winner, four-time Erzbergrodeo winner, five-time Red Bull Romaniacs winner and two-time TKO winner. The German achieved an undefeated FIM Hard Enduro championship in 2023 and he will be gunning for a third TKO win in 2025.

Billy Bolt is one of the most popular Hard Enduro racers in the world. The Husqvarna rider has won five consecutive FIM SuperEnduro championships and has won nearly every race during that five-year span. The British rider won the WESS Hard Enduro championship in 2018 and the inaugural FIM Hard Enduro championship in 2021. Bolt won the 2021 TKO after a last lap pass on Lettenbichler.

The four riders above have combined for 12 TKO wins but there are other riders capable of fighting for the podium. The four riders below are among the favorites to earn a podium at the 2025 TKO.

Jonny Walker has won some of the biggest Hard Enduro events in the world including the Erzbergrodeo and Red Bull Romaniacs. The British rider also has an FIM SuperEnduro championship and an AMA US EnduroCross championship to his credit. Walker is racing the Triumph TF 250 E in 2025 and proved the four-stroke can compete in Hard Enduro by finishing in sixth place at the Erzbergrodeo.

Ryder LeBlond has been climbing up the ranks of the US Hard Enduro championship and the Rockstar Husqvarna rider took his first two career wins during the 2025 season. The Pennsylvanian is hungry to prove that he can mix it up with the top riders to earn a TKO podium.

Will Riordan comes into the final AMA US Hard Enduro championship in third place. The Australian has eight podium finishes in nine rounds so far in 2025. The Sherco rider could be the sleeper pick for a TKO win.

Kawelo Huddy won the won the Hawaiian round of the US Hard Enduro championship and is the master of slick conditions. The Kuai based rider has spent the full season racing on the mainland and comes into the TKO in fifth place in the US Hard Enduro Championship. If it rains, Huddy could be a threat for an upset win.
