■Massive 112mm bore and 90.5mm stroke utilizing huge 112mm forged aluminum alloy pistons with short skirts, and cut away sides riding on chrome moly steel connecting rods.
■Unique two-stage cam drive system creates a compact cylinder head design, reduces overall engine height and creates a lower center of gravity.
■Each bore is lined with Suzukiís race proven SCEM (Suzuki Composite Electrochemical Material) for optimum heat transfer, tighter piston-to-cylinder clearances and reduced weight.
■A compact dry sump lubrication system SASS (Suzuki Advanced Sump System) provides reduced engine height, a lower crankshaft position and lower center of gravity.
■Five speed transmission features carefully selected gear ratios for comfortable cruising in a variety of riding situations.
■Three piece airbox uses dual intakes with 9.5 liters of internal volume working through a pleated fabric air cleaner element.
■The 2-into-1-into-2 stainless steel blacked out exhaust system features Suzukiís digitally controlled SET (Suzuki Exhaust Tuning) system for optimum engine performance and powerful V-twin sound.
■Electronic fuel injection system features the Suzuki Dual Throttle Valve system (SDTV) with 56mm throttle bodies - maintains optimum air velocity for smooth low- to mid-range throttle response.
■A new Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle speed in various conditions.
■Dual spark plug per cylinder ignition system is controlled by the powerful 32 bit ECM for improved combustion efficiency and reduced exhaust emissions.


---Chassis Features---

■High-tensile double cradle steel frame is built to comfortably handle all the power and torque while delivering agile handling and a plush smooth ride.
