Custom Triumph Alchemist Thruxton RS: Fresh, confident, and contemporary

PUBLISHED 30.01.2026

The Alchemist Thruxton RS is the latest custom motorcycle from Charlie Stockwell to roll out from beneath the arches of Triumph London, a build that takes Triumph’s most advanced café racer and refines it through colour, craftsmanship, and restraint.

The build is based on the Triumph Thruxton 1200 RS, Triumph’s most advanced pure café racer. With its 1,200cc parallel-twin engine, Öhlins suspension, Brembo braking, ride-by-wire throttle, and selectable riding modes, the Thruxton RS blends classic café racer proportions with modern performance engineering. It’s a bike that already sits at the sharp end of Triumph’s modern classic range, making it the ideal foundation for a considered custom transformation.

At the heart of the Alchemist build is a striking visual identity. The bespoke paintwork is finished in Miami Mint Pearl and Denim Black, laid down in high-gloss to amplify the Thruxton’s muscular lines. Fresh, confident, and contemporary, the colourway brings a new energy to the café racer silhouette while remaining true to its heritage roots.

Performance and presence come together through a full titanium exhaust system by Hitchcox, featuring beautifully executed pie-cut welded bends. It’s a centrepiece in its own right, being visually dramatic, technically precise, and designed to enhance both sound and performance. The system sits tight to the bike, reinforcing its purposeful stance while delivering a crisp, characterful soundtrack.

Craftsmanship continues at the saddle, where the seat has been completely re-upholstered in charcoal Alcantara and black leather, finished with diamond stitching. A subtle mint-green double frame stitch mirrors the paintwork, tying the entire build together through detail rather than excess, creating the kind of finish that rewards a closer look.
 

The finishing touches elevate the Alchemist Thruxton RS further. Motogadget bar-end mirrors and front indicators clean up the cockpit, while adjustable front levers add both function and finesse. A slim tail tidy integrates an LED rear light for a sharper rear profile, complemented by a headlamp and speedo lowering kit paired with a headlamp cage to bring the front end down visually.

Every piece of bright-work has been treated in black Cerakote, sharpening the overall silhouette and giving the bike a cohesive, modern edge. Subtle upgrades, including billet and machined components from Triumph and Motone, add texture and depth without pulling focus from the build’s core identity.

The result is a Thruxton RS that feels purposeful, refined, and confident. A café racer transformed through colour, craftsmanship, and considered detail. Modern in execution, timeless in intent.
