Entries open for 2024 Red Bull Tennessee Knockout: Three days of racing – Friday, August 23 to Sunday August 25

Racer entries are open for the 2024 Red Bull Tennessee Knockout (TKO). The 2024 TKO will take place from Friday, August 23 to Sunday, August 25, 2024, at the Trials Training Center in Sequatchie, Tennessee.

The fourteenth annual TKO will again be part of the FIM Hard Enduro World Championship (HEWC) in 2024 and will also be part of the AMA US Hard Enduro Championship and serve as the AMA Grand Championship for Extreme Enduro. The top North American riders will take on the best international riders.

The multi-round racing format that attracts a maximum of 500 amateur entries and the best pro riders will start on Friday with the amateur Hot Laps to set the Saturday starting positions.

Saturday will include two rounds of amateur racing that will allow up to thirty riders to earn the opportunity to race in the pro class racing that will start on Saturday afternoon with a Hot Lap on the more difficult pro short course.

Sunday will include three rounds of pro-class racing that concludes with a multi-lap main event that is spectacular for the fans.

The TKO will again include the ECR eMoto championship races for electric motorcycles and electric motorcycle demo rides to add to the fun weekend for racers and spectators.

The top amateur riders will be eligible to qualify directly to the Saturday amateur race two if they finished in the top 50 in the amateur racing at the 2023 TKO or finish in the top 10 in the East, West or Premier AMA US Hard Enduro championships in their respective classes* (Amateur C, Youth and Women’s Amateur class riders will race in Saturday race 1).

The top pro riders will be invited directly to the pro class Hot Lap (new for 2024, pro riders can enter the pro class without an invite).

Racing format

The racing format will be like past years with a Prologue on Friday to set amateur racer starting positions followed by two rounds of amateur racing on Saturday and a multi round Sunday competition for the pro riders, which will include the top thirty finishers from Saturday. The ECR eMoto electric motorcycle class that was a huge success in 2022 will be back and a few other exiting ideas are being developed.

TKO will again pre-qualify the top riders to the multi round Sunday competition. This will include top riders from major US and international off-road racing series and events. Any rider that finished in the top 35 on Sunday at the 2022 TKO, as well as riders that have qualified for a previous TKO Sunday main event, will be qualified directly into the 2023 TKO Sunday program.

The Saturday program will include two rounds of racing and will serve as the AMA Extreme Off-Road Grand Championship for Amateur riders. The overall Amateur winner will be awarded the AMA Extreme Off-Road Grand Championship number one plate.

Classes will be available for A, B, C, Women Pro, Women Amateur, 45+, Youth and eMoto. The top 50 amateur finishers from the 2022 TKO will earn a spot directly into Saturday round two. Amateur riders will also be able to earn spots directly into round two via several AMA Hard Enduro regional championship events.

Riders that do not qualify via one of the AMA regional events can sign up for one of 500 open spots that will compete in a morning qualifying race that can earn a spot in the championship final on Saturday. The top 30 finishers from Saturday will be invited to Sunday’s expert program.

Participation or advancement to a higher class in any AMA or non-AMA Off-Road meet by any rider will result in permanent advancement to that higher class in all AMA-sanctioned Off-Road Competition.
