This is a different system, which appears to use centrifugal force to change the camshaft angle relative to the sprocket - an interesting, if perhaps somewhat inflexible, approach. The VFR disconnects two valves per cylinder (completely) at lower revs. I haven't heard of many actual reliability problems with the Honda system - mainly complaints about driveability; because the system is "binary" - on or off - it can cause some hiccups if you are running the engine near the conditions where it switches over. Suzuki's system will progressively change the cam timing as the RPM changes. How durable ... remains to be seen.
Automotive VVT systems generally use engine oil pressure to actuate a set of vanes within an adapter-housing between the cam sprocket and the camshaft. These systems have generally been reliable. Remains to be seen whether Suzuki's centrifugal/mechanical system is designed to survive being hammered on by every power stroke and every cam lobe ...
I smell bean counters.
Are Suzuki owners actually asking for something different?
To ME (Not a Suzuki owner), this gixxer continues the tradition of being almost indistinguishable from the prior generation aside from the graphics ... Yes, if you put them next to each other, you can spot differences, but the overall theme is the same and it hasn't really changed in 15 years ... I get the feeling that Suzuki was dragged into the ABS / traction control era kicking and screaming ...
