Pepo Rosell, higher often called XTR PEPOis a power of nature. He initially burst onto the scene together with his specialist {custom} workshop, Radical Ducati, earlier than taking a break and relaunching as a solo act. Typically impressed by basic endurance racers, Pepo’s bikes convey a way of velocity—with a touch of eccentricity.
Pepo’s portfolio is dripping with unique twin-cylinder Italian machines, however he’s simply as adept at making use of his abilities to smaller bikes. He’s simply buttoned up this Royal Enfield Guerrilla 450, and it’s each bit as radical as you’d anticipate an XTR Pepo bike to be.
In inventory type, the Guerrilla 450 is a peppy single-cylinder roadster with a glance that deviates from the Indian marque’s conventional aesthetic. However within the arms of Pepo, it’s a feisty Supermone racer with tons of perspective.
“I like singles very a lot,” says Pepo. “So when Royal Enfield proposed that I work with the Guerrilla, I noticed the chance to make a super-single with no compromise—a race bike for observe and street use.”
Pepo began with a 2024-model Royal Enfield Guerrilla 450, however little stays of the unique bike past its body and engine. The motor’s nonetheless inventory inside, nevertheless it’s been liberated considerably, courtesy of a deft airbox mod. Gasses are expelled by way of a forty five mm exhaust header, constructed by Xpipe, and a titanium Spark muffler.
Transferring to the chassis, Pepo binned the manufacturing unit subframe and fabricated a brand new one. The brand new unit kicks the tailpiece up at a far sharper angle than earlier than, and options built-in mounts for the bike’s new rear-set footpegs.
The Royal Enfield Guerrilla 450 additionally sports activities upgraded operating gear at each ends. The entrance forks are Showa models from an Aprilia RSV 1000, held in place by CNC-machined yokes. A modified Aprilia RS 660 swingarm does responsibility on the again, hooked as much as a custom-built Nitron shock.
Pepo additionally specced the Royal Enfield with cast aluminum Dymag wheels, wrapped in Continental Conti Street Assault 2 tires. The dual entrance brakes use Discacciati calipers and 320 mm floating discs, whereas the rear brake makes use of a Brembo caliper (additionally lifted from an Aprilia).
The Guerilla’s sharp new bodywork is quintessential XTR Pepo fare. To create it, Pepo labored intently with Futura 22, a design agency in Turin, Italy, and digital modeler Alberto Caimi. Working from Pepo’s preliminary renders, the crew fine-tuned the general design earlier than 3D-printing molds for all the pieces.
The ultimate elements have been formed out of fiberglass utilizing these molds. The setup features a low-slung entrance fairing on a bespoke mounting system, a sculpted gas tank, and a boxy tail part with a slim racing pad. A transparent strip on the aspect of the gas tank acts as a gas gauge, whereas the rear cowl has a detachable panel that gives fast entry to the bike’s wiring.
An offset headlight provides a touch of retro endurance racing model, whereas a scooped stomach pan drives the purpose dwelling. The cockpit options clip-ons, Domino grips, Discacciati levers, and the OEM speedo, which has been remounted on a {custom} bracket.
Then there’s the Guerilla 450’s energetic livery—a heady mixture of daring colours, chunky graphics, and sponsor logos, complemented by a vivid purple body and a handful of carbon fiber accents.
Pepo considers himself retired lately, so this could be one of many final bikes we see from him, and extra’s the pity. This plucky Royal Enfield Guerilla 450 racer is proof that the person’s capability hasn’t waned one bit—and it makes a robust case for a Guerilla 450 spec collection, too.
