Remember me
Designed with the help of AI-powered software and realized in forged carbon fibre, this Royal Enfield Guerrilla 450 has factory prototype written all over it.
Between CGI whizz-kids and AI prompt-jockeys, it's getting hard to separate fact from fiction these days. But while we admire their skill, the real challenge is turning an ultra-futuristic concept bike into a tangible, rolling machine.
This unreal Royal Enfield Guerrilla 450 started as a digital render, but only because that's a playing field that its creators are well familiar with. It's the work of Autologue Design—an Indian outfit that specializes in bolt-on custom parts and body kits. They're used to making a part pixel-perfect on screen before they drag it into the real world, and they've even developed their own AI-powered automotive design tool to help them do so.
While parts are their bread and butter, Autologue relishes any opportunity for a ground-up custom build. So when Royal Enfield invited the crew to customize the Guerrilla 450 for the marque's annual Busted Knuckles Build-Off, they were all-in.
“Autologue has long been seen as a 'bolt-on builder,' largely because kits and parts are the company’s core business,” says automotive designer Mukul Nanda, who founded the company a decade ago with international cricketer Yuvraj Singh. “But custom motorcycles are where the studio began—and where a lot of its deeper design and fabrication work still happens, often behind the scenes.”
“With the 'Guerrilla 450 ALX,' the goal was to change that perception. The team wanted to build something that felt factory-intended, not aftermarket—a motorcycle that could exist as a Royal Enfield concept while still carrying Autologue’s own identity.”
“We took inspiration from our roots in drag racing, combined with the sharp, muscular design language of the Guerrilla 450. Initial sketches were refined digitally, using our in-house AI design platform, YOURALAI, which has been in development for over two years.”
Although Autologue had a wide array of changes planned for the Guerrilla 450, they were adamant about retaining some of its DNA. They used the stock fuel tank as a template for a custom reservoir, widening it ever so subtly to create a more aggressive look. And they referenced the original side covers for the cutouts in the new aluminum subframe plates, which support the bespoke tail section.
It's worth pausing to appreciate the Guerrilla 450's flawless color scheme. All the bodywork was made out of forged carbon fiber, its unique texture juxtaposed against kinetic silver and yellow graphics. A dash of yellow on the chassis and a polished effect on the subframe add the right amount of contrast.
A sharp fairing dominates the front end, with twin winglets that recall modern superbikes and streetfighters. The fairing's position is adjustable, too, so that the bike can be tailored for either street riding or drag racing, since part of the brief was that the bike would be raced on the strip.
“The overall silhouette was shaped around three principles: organic surfaces, futuristic detailing, and race-ready function,” says Mukul.
The back of the bike sports a waspish tail section, capped off with a 3D-printed TPU seat. The NOS bottle under the tail isn't just there for show—it's part of a complete dry nitrous oxide system with a purge kit. “It underscores that this build is designed to perform, not just pose.”
The lighting is custom too, with acrylic lenses backed by powerful LED lights. The rear turn signals are integrated into the taillight winglets, adding anime flair to the build.
Keeping with the performance theme, Autologue treated the single-cylinder Enfield to a substantial suspension and braking upgrade. A Ducati 848 was scalped for its Öhlins and Brembo components, with Pirelli Rosso IV tires offering maximum grip. The Guerrilla 450 breathes in through a K&N filter and exhales via a GP-style stainless steel exhaust.
Other changes include a sporty belly pan and a set of rear wheel covers. The cockpit features clip-on bars, along with simplified switches, bar-end mirrors, and a Motogadget dash. CNC-machined rear-sets do duty lower down.
Under the hood, Autologue rewired the bike around a Bluetooth-enabled Motogadget module, with a host of features controlled via a smartphone app. The setup includes a keyless ignition, geo-fencing, and an alarm.
“For us,” Mukul adds, “the Guerrilla 450 ALX represents a pivot point—from being known primarily for bolt-on kits to being recognized as a full-scale custom motorcycle design and prototyping house. It went on to win the Busted Knuckles Build-Off, marking Autologue’s first custom build contest victory and our first full custom showcase for Royal Enfield.”
