Royal Enfield RE1000 by GRID Motorcycles
For Busted Knuckles Build Off, GRID Motorcycles did not just customise the Royal Enfield Shotgun 650 – they rebuilt the idea of what it could be.
Named the RE1000, this is a ground-up custom built to stop people in their tracks. Created by GRID Motorcycles, the project goes far beyond a collection of bolt-on parts or surface-level changes. At its core is something never seen before: a world-first 1000cc Royal Enfield parallel twin, developed from the foundation of the 2025 Shotgun 650. That alone makes the bike remarkable. But the story of the RE1000 goes well beyond engine capacity.
From the beginning, the vision was clear and unapologetically ambitious.
GRID set out to build the most eye-catching, show-stopping Royal Enfield motorcycle they could imagine. Something that had never been done before. Something that respected the brand’s heritage, but pushed far beyond expectation in performance, design and craftsmanship. The result is a fully hand-made motorcycle that draws inspiration from drag racing culture and Japanese craftsmanship, while still holding onto a sleek, timeless look that does not feel tied to passing trends.
That balance is a big part of what gives the RE1000 its impact.
It is radical, but it is not messy. It is extreme, but still resolved. Every part of the build has been approached with real intent, and almost every component on the motorcycle has been reimagined or fabricated from scratch in pursuit of something genuinely one of one.
The starting point for the entire project was performance, and that meant beginning with the engine.
While the engine is the only original element retained from the Shotgun 650, what sits inside it is something altogether different. Working with engine builder Jesse Robinson, GRID transformed the original 650 platform into a 1000cc parallel twin, creating what they describe as a world first for Royal Enfield. Externally, the engine still carries a familiar appearance, which makes the transformation even more impressive. Beneath the surface, though, it has undergone major internal changes to become the mechanical centrepiece of the RE1000 and the core of its performance identity.
Around that engine, the rest of the motorcycle was built by hand.
The design and fabrication work was led by Dylan Brown, who meticulously crafted almost every major component on the bike. Central to that is a custom fabricated chrome moly frame, built specifically for the project and then hand polished to achieve a finish that feels both distinctive and timeless. It gives the RE1000 its own structure, stance and identity, while immediately separating it from the production machine it began from.
That same approach continues throughout the rest of the build. The bike features a custom aluminium fuel tank and fenders, all shaped to suit the stripped-back and cohesive design language of the project. It also runs custom handlebars, grips and triple clamps, further reinforcing the fact that this is not a modified Shotgun in the usual sense, but a motorcycle that has been fundamentally rethought from the ground up.
What stands out most is how seamless the final result feels.
With so many one-off parts and hand-built components, it would have been easy for the RE1000 to become visually overworked. Instead, GRID has kept the bike remarkably clean. The overall aesthetic is minimal and sleek, but it still carries a strong aggression in its stance and posture. That tension between refinement and force is what gives the motorcycle so much presence. It feels highly crafted, but it also feels dangerous in the right kind of way – like a machine built with both discipline and a touch of mechanical madness.
And that is really the heart of the RE1000.
It is a showcase of craftsmanship, yes, but it is also a statement of intent. A build that proves how far a platform can be pushed when the brief allows total freedom and the team behind it is prepared to chase something extraordinary.
That thinking ties directly back to the spirit of Busted Knuckles Build Off.
As GRID noted, two points from the competition brief stood out from the start: no constraints on modifications, and a requirement for the build to reflect both creativity and a strong understanding of Royal Enfield’s brand values. The RE1000 answers both of those points in a big way. It embraces the freedom of the competition fully, while still staying connected to the broader Royal Enfield story.
That connection comes through most clearly in the way the build reflects Custom World – Royal Enfield’s long-running celebration of creative, boundary-pushing custom motorcycles from around the world. The brand has always built motorcycles with a strong mechanical honesty and a custom-friendly foundation, and the RE1000 takes that idea to its outer limit. It respects the DNA of the original machine, but uses it as a canvas for something radically different.
Royal Enfield has a rich history of building motorcycles that are beautiful, robust and dependable. The RE1000 does not reject that history. It builds on it. It shows that an iconic machine can evolve dramatically without losing the spirit that made it worth building on in the first place.
For Busted Knuckles Build Off, that makes the RE1000 one of the boldest interpretations of the brief. A fully hand-built custom. A world-first engine. A motorcycle that pushes deep into new territory while still carrying the Royal Enfield name with purpose.
It is ambitious, uncompromising and impossible to ignore.
