Just two weeks after winning the Red Bull Romaniacs Hare Scramble in Romania, Red Bull KTM Factory Racing’s Manuel Lettenbichler made the journey across the pond to the Trials Training Center in Sequatchie, Tennessee, where he dominated this year’s Tennessee Knockout (TKO). Since US team rider Josh Toth was injured and unable to race, KTM USA supplied Manni with Toth’s 2019 300 XC-W TPI to ride in Tennessee. Manni brought his own suspension, tires, mousses, handlebar, grips, and exhaust, and the bike was prepared by Cody Webb’s mechanic, Robbie Goolsby. Before the race, Goolsby gave us an exclusive look at Manni’s setup.

The KTM off-road team in the United States (FMF KTM Factory Racing) runs FMF exhausts, but the European team uses Akrapovič, so Manni brought his own. As far as the engine itself, a full Hinson Racing clutch assembly is used, and Manni prefers to run soft springs in it. Aside from that, Goolsby says the powerplant is mostly standard.

“The factory gave us a spec engine, which is pretty close to the stock setup [with] just little things changed here and there,” Goolsby said. “[The] ECU mapping is from the factory as well.”

The radiators are stock, but Goolsby runs a little bit of sheeting over the radiator hoses so that no sticks or rocks hit it and puncture the hose. To keep the bike running cool in the sometimes slow-going conditions of hard enduro, there is a KTM PowerParts radiator fan that is operated by the ECU.

Manni brought his personal suspension setup from Europe including a WP Cone Valve fork and a WP Trax shock. He brought his own Michelin tires as well, which are mounted onto Excel rims laced to standard hubs, and the final drive ratio of 12/49 is driven by a Regina O-ring chain. The front and rear brake rotors are Moto-Master units that utilize the stock sizes—260mm up front and 220mm in the rear. An Acerbis disc cover protects the front rotor while the rear is a solid rotor. For extreme races, Manni will run a Zip-Ty Racing sharkfin to help keep obstacles from damaging the rear disc as well.

At the front of the bike, Manni runs a Renthal 996 Twinwall handlebar and Xtrig triple clamps with a 22mm offset.

Manni runs a Renthal 996 Twinwall handlebar and Xtrig triple clamps with a 22mm offset. The front brake and clutch lever are both stock. For extreme races, the German off-roader will use a P3 Carbon skid plate too. Other items include an Enduro Engineering brake tip, Raptor footpegs, and KTM PowerParts straps in case he gets stuck and has to get off and pull the bike. Goolsby also shed light upon the mousses Manni brought with him.

“What I’ve been finding out going over to Europe [is that] the Europeans have been getting special mousses made for extreme enduro,” Goolsby explained. “They don’t have to drill them anymore; they’re just super soft in general [and] fit in the tires they run. Sometimes we’ve got to run three rim locks with them though, just because of how flat the tire is going across stuff.”
