3Intake Valve and Exhaust ValveCamshaftFuel InjectionDual Spark TechnologyAssist camAssist FunctionSlipper camSlipper FunctionAlready famed for its performance and reliability, the compact 398cm3 liquid-cooled, DOHC, dry-sump engine has been thoroughly updated to enhance its torquey, free-revving nature to deliver a superior balance of performance and controllability, and to comply with the latest emission and noise regulations.In addition to providing faithful response to throttle action applied in a satisfying linear manner, the new engine is fully compliant with Euro 5+ emissions standards, OBD II requirements, as well as the latest regulations pertaining to noise. This is in part thanks to the introduction of dual spark plugs, which contribute to smooth power delivery, lower fuel consumption, lower emissions, linear throttle response, easier engine start-ups and a more stable idle. It is also backed up by Suzuki’s Ride-by-Wire Electronic Throttle and fuel injection systems, which enable finer precision over fuel feed control.Refined internalsA pair of light weight titanium intake valves combine with hollow sodium-filled exhaust valves to help maximize combustion efficiency and output. A new cylinder head design enhances combustion while new camshaft profiles limit exhaust emissions and enhance torque production, contributing to the engine’s free-revving nature, its staying power at low speeds, and the satisfying punch it delivers in the high rev range. In addition, new piston and crankcase designs combine to reduce mechanical loss by up to 20%.New exhaust systemThe exhaust system employs a new dual-stage catalytic converter* and O2 sensor that help satisfy Euro 5+ emissions standards. Also featured is a double-wall muffler design that helps protect your legs from extreme heat, complies with noise regulations, and also contributes to the slim body profile.*Not available in some marketsSuzuki Clutch Assist System (SCAS)The Suzuki Clutch Assist System (SCAS) delivers confidence-inspiring sure shifts while at the same time realizing a light touch to clutch lever operation that helps reduce fatigue on long rides and contributes to smoother shifting. It’s a blessing, whether riding in traffic or out exploring trails.Faithful, fast and oh so funThis masterpiece of engine artistry is destined to dominate for years to come
