Engineered by Suzuki for the sport motorcycle segment, the 2021 Suzuki Ecstar GSX-RR features a 1000 cc (61 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 236 HP (172.3 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 236 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ecstar GSX-RR measures 157 kg (346 lbs) dry, translating to a power-to-weight ratio of 1.5 HP/kg (0.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 1-liter (0.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 340 km/h (211 mph).
