Built around Arch's sport motorcycle platform, the 2021 Arch KRGT-1 pairs a 2032 cc (124 cu in) v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 120 HP (87.6 kW) while maximum torque reaches 164.1 Nm (121 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 59.1 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the KRGT-1 measures 244 kg (538 lbs) dry, translating to a power-to-weight ratio of 0.49 HP/kg (2.03 kg per horsepower). Rider ergonomics and chassis geometry center around a 706 mm (27.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,727 mm (68 in) wheelbase engineered for planted straight-line stability. The 18.93-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
