Engine

• Powerful 1340 cc in-line 4-cylinder fuel-injected, liquid-cooled DOHC engine built to deliver a broad wave of torque for effortless acceleration.
• Forged three-ring aluminum-alloy slipper pistons provide superior strength, while PVD-coated rings reduce friction and improve cylinder sealing.
• The chrome nitride Physical Vapor Deposition (PVD) piston ring coating is harder and smoother than conventional chrome plating, reducing friction while improving sealing to the cylinder.
• Suzuki Composite Electrochemical Material (SCEM) cylinder plating improves heat dissipation, durability and ring seal.
• U-shaped cutouts in the cylinder-bore sides allow air pressure created by descending pistons to escape to adjacent cylinders to reduce internal pumping pressure and mechanical power losses.
• Lightweight titanium valves allow use of light valve springs and high lift while maintaining accurate valve control.
• Iridium spark plugs produce more complete combustion and last longer than conventional plugs.
• Curved radiator with a compact, dense-core design and two ECM-controlled electric fans keep the engine temperature stable.
• Suzuki Clutch Assist System (SCAS) serves as back-torque-limiting system for smooth downshifts and also contributes to a light clutch pull.
• Close ratio, constant-mesh 6-speed transmission uses dedicated oil spray to the 4th, 5th and 6th gears to reduce friction, wear and mechanical noise during high-speed operation.
• Suzuki’s advanced fuel-injection system with tapered, 44 mm double-barrel Suzuki Dual Throttle Valve (SDTV) induction improves combustion efficiency and smooth’s throttle response.
• 2 – 12-hole fine-spray injectors on each throttle body improve fuel atomization for better combustion efficiency while reducing fuel consumption.
• Idle Speed Control (ISC) system improves cold starting and helps maintain stable engine idle under a variety of conditions.
• Suzuki Pulsed-secondary AIR-injection (PAIR) system ignites unburned hydrocarbons (HC) and reduces carbon monoxide (CO) emissions.
• Large-volume catalyzer in the twin-silencer exhaust permits high flow while further reducing HC, CO and nitrogen oxide (NOx) emissions.
• Suzuki Drive Mode Selector (S-DMS) lets riders select engine power output to match preferences or riding conditions.
