Royal Enfield 650: Royal Enfield has once again captured the hearts of motorcycle enthusiasts with its latest custom creation, Project Delta. This one-off vintage-inspired motorcycle is a collaboration between Royal Enfield and the renowned custom bike builder, Purpose Built Moto. Drawing inspiration from the 1940s and 1950s motorcycling era, Project Delta reimagines the modern Royal Enfield Super Meteor 650 with a retro twist. The result is a stunning blend of classic design and contemporary engineering, making it a true collector’s piece.
The design of Project Delta pays homage to iconic motorcycles like the Super Meteor 700 and the Flying Flea from World War II. The custom build features a hardtail-style frame, hand-shifted gears, and solid-mounted bars, all of which are reminiscent of the bikes from the 1940s. However, it’s not just about nostalgia—Project Delta incorporates modern updates such as an in-frame oil cooler and a monoshock conversion, ensuring that it’s as functional as it is beautiful. The motorcycle’s 23-inch front and 19-inch rear spoked wheels, along with the handcrafted girder fork, further enhance its vintage appeal.
Despite its classic aesthetics, Project Delta is powered by Royal Enfield’s modern 648cc parallel-twin engine, which delivers 47 horsepower and 52 Nm of torque. This air- and oil-cooled engine ensures that the bike performs as well as it looks. The bespoke paintwork, featuring black, gold, and cherry red hues, is inspired by the Art Nouveau movement, adding a touch of elegance to the rugged design. While Project Delta is a prototype and won’t be available for purchase, it showcases Royal Enfield’s commitment to innovation and its ability to push the boundaries of motorcycle design.
