One hundred of these Rough Crafts x Shotgun 650 bobbers have been built and will be shipped to four territories: India, North America, Europe and Asia Pacific, 25 bikes each.
This exclusive collaboration between Royal Enfield and the Taipei custom workshop is based on Winston Yeh’s Caliber Royale. However, to be candid, it’s been stripped of almost everything that made the progenitor so remarkable. It could be dismissed as a paint job. Nonetheless, they’ve all been snapped up by eager collectors. Here’s why.
Rough Crafts x Shotgun 650
Rough Crafts & Winston Yeh
Rough Crafts has built a following and reputation for fabricating customs with striking appeal. The builds somehow manage to be both understated and lavish.
Using a go-to band of local artisans to execute his vision, Yeh’s style has evolved over the years into the distinctive mesh of matt and gloss dark finishes, flowing yet angular sculpted bodywork complemented by supremely executed ornate gold accents.
The workshop is among a cadre of custom builders whose work is immediately identifiable. It never misses the mark. Yeh is a prolific builder, with an enviable portfolio of work that other builders and manufacturers use as inspiration.
Showstopper
When Winston Yeh’s showstopper, the Caliber Royale, was revealed at EICMA 2025, some people’s heads exploded. It was understandable. Rough Crafts had convincingly transformed Royal Enfield’s sedate, short-wheelbase cruiser/bobber into an aggressive-looking stretched-out racer with a dustbin-esque front fairing. All of this without any cuts or any changes to the engine.
It’s a custom motorcycle that wouldn’t look out of place on the set of a retro-futuristic movie, ridden by either the protagonist or antagonist. Understatedly, the reception was good.
Yeh has previous form with Royal Enfield’s 650 platform. He splendidly reworked a Continental GT 650 into a café-racer, the Midas Royale. Therefore, a limited edition run with Royal Enfield was likely inevitable.
Progenitor Build – The Caliber Royale
The Caliber Royale build sought to achieve maximum visual impact without altering the frame. The engine was also left untouched.
Starting up front, fully adjustable Öhlins FGRT 213 superbike forks are clamped by CNC-machined Rough Crafts yokes. Beringer brakes hold discs cut to match the spoke pattern of the BST five-spoke carbon wheels, wrapped in Pirelli Diablo Supercorsa SP tyres.
Moving to the back, the stock swingarm made way for a billet aluminium unit from 101 Factory, 100mm longer than standard. (Blacked-out Blackline piggyback shocks sit above it.) Coupled with the new forks, that’s how the bike’s stretched, low-slung stance was achieved.
Over the top of all this sits entirely new bodywork, built around the scalloped dustbin fairing, with stacked KOSO LEDs sunk into its left-hand side and the scallop motif carried through to the tank and tail.
Yeh worked with his usual collective of Taipei artisans on the Royale: Faber Studio, CH Moto, JZO Crafts, Simon Fiber Craft, Rover Works for the paint, Churui Leather for the saddle, and jeweller 2 Abnormal Sides for the hand-cast emblems.
The Standard Shotgun 650
Mechanically, there isn’t anything different about this limited edition versus the base Shotgun model. This machine uses Royal Enfield’s air and oil-cooled 648cc SOHC parallel twin found across the range, including the Bear, Continental GT and Interceptor. With a 9.5:1 compression ratio, it generates a non-blistering 46bhp at 7,250rpm and 52.3Nm at 5,650rpm through a six-speed box.
Like Yeh’s original, the frame is untouched. The steel tubular spine carries a Showa Separate Function Big Piston upside-down fork and twin shocks at the rear, with a single 320mm front disc, a 300mm rear and dual-channel ABS.
It rolls on an 18-inch front and 17-inch rear, and is surprisingly weighty at 240kg kerb. The 795mm seat height keeps it accessible.
The Refined Limited Edition – Rough Crafts x Royal Enfield
The silhouettes of the two bikes are vastly different, connected by the distinct Rough Crafts motif. This limited-production Shotgun has none of its forebear’s extreme bodywork or its stretched-out low stance. Its proportions remain unaltered, mirroring the standard Shotgun.
However, it emulates the dark and gold livery of the (technically a prototype) original, down to the style of the tank emblem designed by 2 Abnormal Sides. It’s a decadently refined Shotgun.
The jet-black gloss sits against matt stealth-black, the two split by a hand-applied gold-leaf stripe that follows the line of the tank. It curves around the side panels and is picked up again along the side of the rear mudguard. Design continuity is maintained on the front mudguard, which also has gold piping.
On the top of the tank you’ll find a Rough Crafts shield beside the production number. On the tank flanks you’ll find the distinctive hand-cast brass emblem badges.
The vertical- and diamond-quilted stitch pattern from the Royale is echoed on the saddle. Down at the front end, gold inner fork tubes lift the black, matched by contrast-cut rims at both ends. Bar-end mirrors and a blacked-out exhaust finish it.
Buyers will also receive a numbered gold-on-black print of the Caliber Royale sketch, designed and signed by Yeh – a valuable addition for the lucky one hundred.
Price & Availability
Priced at £8,150, this limited edition is £1,301 more than the standard bike. The registration form went live on the Royal Enfield website on 15 July, 2026, at 6:30 AM BST. Sales began on 27 July, 2026, at 6 PM BST. All bikes were sold out soon after, unsurprisingly.
Opinion
It’s fair to say Yeh’s one-off machine is spectacular; elegantly muscular, with its distinctive sculpted, yet brutish front end.
This limited edition is more understated but no less cultivated. The standard Shotgun models next to both bikes appear positively underdressed, even the flashier iterations.
The finish and the brasswork of this Shotgun are unmistakably Rough Crafts. The designers have soundly carried through the design language of the Caliber Royale, on a machine built to be ridden (hopefully) rather than displayed.
It would be easy to write off this bike as a styling exercise (which of course it is, dummy) or just as a paint job. That misses the point. The goal is styling, or more specifically bringing Rough Crafts’ visual signature to a production Royal Enfield. That’s been decidedly accomplished.
Nonetheless, I’ve been struggling to articulate why I’ve not been more excited about this limited edition. I love the base bike and I’m a fan of Yeh’s works. Then it dawned on me. I’ve been judging the collaboration bike against the Caliber Royale, an extraordinary build.
Judge the limited edition against its progenitor, and you see a modest, less impressive custom build. Judge it on its own merit, and it’s an exceptional factory custom.
Rough Crafts’ characteristic dark and gold aesthetic, coupled with sculpted bodywork and ornately refined embellishments, has long captivated New Wave custom aficionados, and I suspect these machines will truly become collector’s pieces.
The truth is £1,301 buys you a dark paint scheme, hand-applied gold leaf and a numbered tank. Or, put another way, a Winston Yeh build for the price of an annual service or two.
