Royal Enfield has joined forces with lifestyle brand Deus Ex Machina to produce a limited-run version of its Shotgun 650 cruiser, dubbed Son of a Gun. The custom model keeps the standard bike’s mechanicals but adopts a darker, more refined look and will be capped at 100 bikes worldwide.
Design and mechanics
The Son of a Gun retains the Shotgun’s air/oil-cooled, 648cc parallel-twin engine that Royal Enfield introduced for the 2024 lineup. There are no reported changes to performance or the bike’s core mechanical specification.

Visually, the special edition favors a deep red finish contrasted with blacked-out components on the engine, frame, and exhaust. Deus’ styling touches reshape the profile without altering the bike’s foundations.
Custom touches and owner extras
Deus supplied several bespoke elements that distinguish this release from the regular Shotgun 650. Details added by the collaborator include unique tank and side-cover graphics, brown handlebar grips and an embroidered leather seat.

- Embroidered leather seat
- Distinctive logos and brown grips
Launch context and availability
Royal Enfield unveiled the Son of a Gun at the Milan show alongside other recent introductions: the Himalayan 750, Continental GT 750 and the Flying Flea S6 electric scrambler. The company has not released official pricing, and UK availability remains unconfirmed.
Previous limited Shotgun collaborations have carried a modest premium over the standard model and sold out quickly. Early 2025 saw a tie-up with US kit brand Icon Motorsports, finished in red, white and blue and limited to 100 units. That was followed by a special run with Taiwanese custom house Rough Crafts, which used a black-and-gold palette.
Industry perspective
Motorcycle News notes that these special-edition Shotguns are polarizing in style but typically attract strong buyer interest. Given past demand, the Deus collaboration is expected to move fast once orders open.
