Racer entries are open for the 2025 Red Bull Tennessee Knockout (TKO). The 2025 TKO will take place from Friday, August 8 to Sunday, August 10, 2025, at the Trials Training Center in Sequatchie, Tennessee. The fifteenth annual TKO will again be part of the AMA US Hard Enduro Championship, serving as tenth and final round of the premier championship and round five of the East Hard Enduro Championship.

The world’s top Hard Enduro racers have competed in the Red Bull Tennessee Knockout in the past and that is expected to continue in 2025. Germany’s Mani Lettenbichler won the 2024 TKO over Canada’s Trystan Hart and South Africa’s Wade Young. The TKO management team is working on confirming several of the top international rider’s participation for 2025.

The 2025 TKO will again be limited to 500 participants, which has sold out in the past. Riders can enter here.

The multi-round racing format that attracts up to 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 Sunday pro competition. The pro riders will kick off their weekend with a Hot Lap on Saturday afternoon. Sunday will include three rounds of pro class racing that concludes with a multi-lap main event that is spectacular for the fans.

TKO will again include the ECR eMoto championship races for electric motorcycles (now with both eMoto Expert and eMoto Amateur classes) and the electric motorcycle demo rides sponsored by Surron to add to the fun weekend for racers and spectators.
