• The 109 cubic inch (1783cc), eight-valve, DOHC, 54-degree, liquid-cooled, V-twin engine is designed to produce a massive tractable power and responsive torque.
• Huge 4.4-inch (112mm) forged aluminum-alloy pistons. These are one of the largest reciprocating gasoline engine pistons being used in any production passenger car or motorcycle while featuring a race-proven design to reduce friction and inertial mass.
• Each of the large cylinders is lined with Suzuki's race proven Suzuki Composite Electrochemical Material (SCEM) for optimum heat transfer, tighter piston-to-cylinder clearances, and reduced weight.
• Suzuki Advanced Sump System (SASS), a compact dry sump lubrication system, provides reduced engine height, a lower crankshaft position, and a lower center of gravity.
• Suzuki's class-leading electronic fuel-injection system features the Suzuki Dual Throttle Valve system (SDTV) with 56mm throttle bodies, which maintains optimum air velocity for smooth low- to mid-range throttle response.
• A unique two-stage cam drive system creates a compact cylinder head design, reduces overall engine height, and creates a lower center of gravity.
• A dual spark plug per cylinder ignition system is controlled by a powerful 32-bit ECM for improved combustion efficiency and reduced exhaust emissions.
• A three-piece, 9.5-liter volume airbox (with dual intakes) includes two pleated fabric air cleaner elements located on both sides of the engine.
• The two-into-one-into-two chrome-finished stainless steel exhaust system features Suzuki’s digitally-controlled SET (Suzuki Exhaust Tuning) system for optimum engine performance and
