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 massive 112mm bore and 90.5mm stroke is complemented by huge 112mm forged aluminum-alloy pistons featuring race-proven design to reduce friction and internal mass, with short skirts, and cutaway sides riding on chrome-molly steel connecting rods.
Engine bore is lined with Suzuki's race proven SCEM (Suzuki Composite Electrochemical Material) for optimum heat transfer, tighter piston-to-cylinder clearances and reduced weight.
A dual spark plug per cyclinder ignition system is controlled by a powerful 32-bit ECM for improved combustion efficiency and reduced exhaust emissions.
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 three-piece, 9.5-liter volume airbox (with dual intakes) includes two pleated fabric air cleaner elements located on both sides of the engine.
