With the new EnduroCross season fast approaching, Jonny Walker has given fans an exclusive look at how he sets up his Triumph 450 for the battles ahead. Filmed at the Aus Ranch in North Carolina, Walker walks us through the details of his practice bike — the one he’s been training on until his race machine is fully built.
Handlebars, Throttle & Controls
At the cockpit, Walker runs Renthal 827 Fat Bars, preferring the extra flex over twin wall options. “It just feels less stiff, especially in the rocks,” he explains. A G2 billet throttle tube replaces the standard plastic version, providing extra durability and a smoother feel.
Triple Clamps & Wheels
He trusts X-Trig triple clamps for stability into corners: “With standard clamps you can tuck the front easier — these give more comfort and confidence.” Wheels come from Haan, paired with Galfer discs, including a thicker 5 mm rear rotor for the demands of EnduroCross.
Engine & Gearing
The Triumph’s 450cc powerplant remains stock, but the gearing is tuned with Renthal sprockets: 12 teeth up front and 50 on the rear. This setup lowers the gearing, allowing Walker to ride comfortably in second gear across most sections.
Foot Pegs & Seat Setup
He runs Raptor pegs, set minus five down and minus five back, helping him find balance and lift the front wheel in the rocks. The Guts Racing seat is a taller option, complete with grip ribs that keep him planted under the Triumph’s explosive power.
Protection & Suspension
A Bulletproof Designs rear disc guard keeps things safe, while suspension is mostly stock but revalved. Walker even reveals a personal trick: he removes a frame bolt to allow more flex. “It makes such a difference in the rocks — the bike squats down and finds more traction,” he says.
Tires & Mousses
As always, Walker trusts Michelin Extreme tires with mousses tailored for conditions. For EnduroCross he runs a solid 140, while for extreme enduro he often drills or cuts the mousse for extra compliance.
Exhaust & Weight
For now, the Triumph runs its stock exhaust, though Walker confirms an Akrapovič system is on the way to shed more weight. Despite being a 450, he insists the bike feels light: “More power actually makes it feel lighter. We’ll keep working to save grams, but I love how it rides.”
Looking Ahead
While this machine is his practice bike, Jonny notes that Jean is building his official race bike in time for the season opener in Arizona in just four weeks. Until then, he’s logging hours at the new Triumph test track and fine-tuning the details that could make all the difference when the EnduroCross gates drop.
