Engineered by Sharmax for the custom - cruiser motorcycle segment, the 2025 Sharmax Custom 1000 RST Roadster pairs a 800 cc (48.8 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 55 HP (40.1 kW) while maximum torque reaches 66 Nm (48.7 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 68.8 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Custom 1000 RST Roadster measures 363 kg (800 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.6 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,600 mm (63 in) wheelbase engineered for planted straight-line stability.
