An automatic Idle Speed Control (ISC) system is integrated into each throttle body, and produces stable idle while improving cold starting and reducing emissions immediately after start up.
|
|
|
|
|
|
Each 39-millimeter throttle body carries a 10-hole fuel injector. The extra-fine atomization injectors produce an average spray particle diameter that is smaller for improved combustion efficiency.

|
|
Suzuki Composite Electrochemical Material (SCEM) liner reduces friction and improves heat transfer, durability and ring seal.
|

SFV650 is powered by a sporty fuel injected, DOHC 90-degree V-twin engine based on the proven SV650 powerplant famous for its long term reliability, broad power and quiet rumble.
|
|
|
|
|
|
645-cubic-centimeter displacement with a bore and stroke of 81 x 62.6 millimeters and a compression ratio of 11.5:1.
|
|
|
|
|
|
Each cylinder head features a compact combustion chamber with two 31-millimeter intake valves set at 14 degrees from the cylinder centerline and two 25.5-millimeter exhaust valves set at 16 degrees from the cylinder centerline.
|
|
|
|
|
|
New single valve springs reduce inertia weight and mechanical losses while maintaining accurate valve control.
|
|
|
|
|
|
Dual spark plugs cylinder heads feature iridium spark plugs to reduce spark plug electrode degradation and allow the electrode to be finer producing a more intense, hotter spark and further enhancing combustion.
|
|
|
|
|
|
Conventional pressed in iron liners are replaced with Suzuki's own race proven nickel-phosphorus-silicon-carbide coating (SCEM), which reduces friction and improves heat transfer, durability and ring seal.
|
|
|
|
|
|
Increased low- to mid-range torque output as well as a broad and smooth power delivery are produced through changes in cam profiles, valve lift, a 10-percent increase in crankshaft inertia, newly staggered intake and exhaust tract lengths and an increase in exhaust system volume. All this without affecting top end power.
|
|
|
|
|
|
Clutch release mechanism is changed from ball-screw type to cam type system and the transmission gear engagement dogs are strengthened to help improve shifting of the six-speed transmission.
|
|
|
|
|
|
To reduce mechanical noise, a scissor type primary gear is split length wise with the two halves spring loaded, and the clutch and countershaft sprocket covers are now double layered for additional sound reduction.
|
|
|
|
|
|
New more efficient radiator is lighter and narrower, while the new liquid to liquid oil cooler reduces weight.
|
|
|
|
|
|
Fuel pump is lighter and more compact and located within the 15 liter fuel tank.
|
|
|
|
|
|
An oval throttle pulley helps smooth low rpm / mid-range power delivery.
|
|
|
|
|
|
SDTV fuel injection system uses two butterfly valves with the primary valve controlled by the rider and the secondary throttle valve controlled by the engine management system to maintain proper intake air velocity needed for maximum combustion efficiency and improved throttle response.
|
|
|
|
|
|
The newly patented Suzuki Idle-speed Automatic Control (SIAC) system is integrated into each throttle body, using internal passageways to eliminate external hoses and control valves. A notch machined into the secondary butterfly valve shaft precisely matches the volume of air flowing through the idle circuit with actual throttle position, producing stable idle while improving cold starting and reducing emissions immediately after start up.
|
|
|
|
|
|
The engine is so efficient in burning fuel that it doesn�t need a secondary system to inject fresh air into the exhaust ports to ignite unburned hydrocarbons.
|
|
|
|
|
|
The SFV650 has a catalyst built into an exhaust chamber mounted underneath the engine and connected to a stylish upswept muffler.
|
