Suzuki says the larger mufflers (boasting a triangular cross section) were necessary to allow the bikes to produce more power while still meeting the latest sound and emissions regulations. The exhaust chamber mounted underneath the engine carries a catalyzer to further reduce emissions.
An electronically controlled steering damper produces less damping force for lighter steering at lower speeds, and more damping force at high speeds.
Cast aluminum-alloy front and rear wheels are reportedly lighter, more rigid and stronger due to a new offset-three-spoke design with curved spokes matching the direction of wheel rotation.
New 10mm NGK spark plugs produce a hotter spark for more complete combustion. Suzuki says the plugs also have twice the service life of a conventional spark plug electrode.
