The Suzuki Clutch Assist System (SCAS) reduces the force needed to pull in the clutch lever so clutch operation remains light. The system produces smooth downshifts by reducing pressure on the clutch plates under deceleration.

Low maintenance shaft drive delivers efficient power delivery.

Well-placed and easy-to-use helmet holder on the rear fender’s left side.

Each aluminum-alloy cylinder is plated with Suzuki Composite Electrochemical Material (SCEM), a coating of nickel-phosphorus-silicon-carbide that reduces friction and increases heat transfer. The result is increased durability and ring seal. Each piston’s upper compression ring and oil control ring are given a chrome-nitride coating to make them harder and smoother to further reduce friction.

Dual spark plugs for each cylinder contribute combustion and fuel efficiency.

Suzuki Dual Throttle Valve (SDTV) induction system is enhanced by the 32-bit engine control unit that instantly delivers the optimum fuel-air mixture and power output. The system – it’s the same design used in Suzuki championship-winning GSX-R sportbikes – delivers seamless throttle response while boosting fuel efficiency and delivering strong torque.

To further reduce mechanical noise, each cylinder head’s cam cover is separated from the cam bearing caps, and a rubber gasket is used between the cylinder head and the cam cover.

An automatic Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle under varying conditions.

To maximize air induction for best power and torque, the C90 features a unique system that uses three separate air-cleaner boxes feeding the engine. This air induction system increases engine output without sacrificing style or fuel-tank capacity.
