Engineered by SWM for the custom - cruiser motorcycle segment, the 2025 SWM Custom V1200 Stormbreaker Amaranth relies on a 1200 cc (73.2 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 60.4 HP (44.1 kW), transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 50.3 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 Custom V1200 Stormbreaker Amaranth measures 262 kg (578 lbs) dry, translating to a power-to-weight ratio of 0.23 HP/kg (4.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 6 L/100 km provides an estimated theoretical range of roughly 233 km (145 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
