New black-painted frame and swingarm for improved appearance.

Engine Features

SV650-based 645cc 90 degree V-twin, DOHC 8-valve, liquid-cooled engine with revised cam profile and 4% more crankshaft inertia for stronger low-to-mid-range power.

Electronic fuel injection features the Suzuki Dual Throttle Valve System (SDTV) - maintains optimum air velocity in the intake tract for smooth low-to-mid rpm throttle response.

Auto Fast Idling System (AFIS), automatically sets throttle valve opening during cold engine starts by monitoring coolant temperature Digital ignition system provides optimum ignition timing with separate maps for each cylinder.

Lightweight shim-under-bucket valve system operates 31mm intake and 25.5mm exhaust valves, plus valve timing with emphasis on low-rpm power SCEM (Suzuki Composite Electro-chemical Material) plated cylinders minimize cylinder size and improve heat dissipation.

High-efficiency liquid cooling system for optimum engine operating temperature - includes compact oil cooler.

Smooth shifting 6-speed transmission with cable operated clutch - final drive ratio lowered from SV650 for improved low rpm performance.

Plastic outer clutch cover and engine sprocket cover for reduced weight and noise.

Plastic outer clutch cover and engine sprocket cover for reduced weight and noise.

High-mounted stainless steel exhaust system with aluminum muffler tuned to enhance engine torque and low-to-midrange performance.

PAIR - air injection system reduces CO and HC emissions - California model equipped with catalyst in exhaust to further reduce emissions.
