Maratha Motorcycles Unveils 9-Foot Royal Enfield Monarch Chopper With 310mm Monster Rear Tyre

Forget everything you know about factory Royal Enfield cruisers.

Built out of a workshop in Mumbai by Maratha Motorcycles, the Monarch stretches nine feet from tip to tail and anchors its stance on an immense 310-section rear tyre. It is long, raked out, and completely divorced from assembly-line pragmatism. While standard production thumpers prioritize upright city commuting and highway chugging, this one-off showpiece treats the venerable 500cc single-cylinder platform as raw material for a classic American-style wide-tire chopper.

Bespoke Softail Geometry and Demons Cycle Wheels

The build centers around an entirely bespoke chassis designed to house extreme running gear. Up front, Maratha Motorcycles discarded the conventional telescopic forks in favor of an old-school custom springer suspension unit. Out back, the motorcycle runs a custom-fabricated softail swingarm damped by twin monoshocks hidden beneath the structure, yielding rigid hardtail aesthetics without fully sacrificing suspension travel.

The wheels redefine the motorcycle's geometry. Up front spins a massive 23-inch by 3.5-inch Chrome Mammoth 48 Fat Spokes wheel wrapped in a 120/70 R23 tyre. The rear takes things to an extreme rarely attempted on Indian donor platforms: an 18-inch by 10.5-inch Chrome Mammoth rim imported from Demons Cycle in the United States, shod with a 310/35 R18 Vee Rubber Monster Radial tyre.

Design Context: Installing a 310mm rear tire on an engine originally engineered for a 120-section hoop presents severe driveline challenges. To avoid engine offset issues and keep the center of gravity aligned, Maratha Motorcycles engineered a secondary chain-drive mechanism, transferring torque outward from the countershaft sprocket before sending it straight back to the Demons Cycle rim.

Handcrafted Sheet Metal and Custom Detailing

Virtually every cosmetic panel on the Monarch is hand-beaten metalwork fabricated in-house. Maratha Motorcycles formed a sculpted fuel tank topped with a custom machined cap, mated to bespoke side covers, a tight-radius rear fender hugging the 310mm radial, and a custom cone-style exposed air filter. Exhaust gases exit through a sweeping, curved open pipe exiting low on the right side.

The rider sits low in a hand-stitched solo saddle finished with leaf-pattern embroidery. The cockpit features an extra-wide handlebar equipped with machined custom grips, chrome-finished hand levers, matching footpegs, and LED bar-end indicators that double as parking lamps. Illumination comes from a compact rounded LED headlamp at the front and a minimal LED brake light integrated into the tail section. Stopping duties are handled by disc brakes mounted at both hubs, with the front registration plate affixed to the springer legs and the rear plate offset to the side.

Finished in deep pearl black paired with metallic red and layered with silver flakes, the Monarch carries hand-applied gold-leaf graphic work across the metal. Maratha Motorcycles noted that completing the build required thousands of man-hours of manual labor, alongside a matching custom helmet finished in identical paintwork. The builder has kept the exact 500cc donor variant and internal engine specs private, keeping the spotlight purely on structural fabrication and visual audacity.
