VARIABLE vALVE TIMING & FINGER PUSHERS MAY JUST BE ENOUGH TO PUT THE NEW 1000GSZR ON TOP OF THE POWER LEAGUE
Opposite other variable valve timing systems, Suzuki's setup has steel balls that work on the intake cam and move via centrifugal force to rotate the intake came at high rpm, thus retarding the intake cam timing and allowing for more valve overlap, for more top-end power. While this system should add very little weight to the engine, it'll be interesting to see how engine character is affected, with the most important point being the engine dynamic as it goes from less valve overlap to more. Honda's VTEC system on the latest VFR almost makes the bike feel like it has split personality syndrome, while Ducati's variable valve timing system on its new Multistrada has been nothing but good as it allows the bike to run smooth at lower rpm while offering good power up top.
Additionally, a finger follower rocker arm system for valve actuation (rather than a bucket-tappet system) reduces moving mass and enables increased valve lift and for the new GSX-R to run a higher peak rpm.

Well as expected the all new Engine puts out a lump more power than any other current litre super bike straight out the crate. However the big plus is that the power comes through the entire range no peaks and troughs are down to the variable cam timing, This alone gives it a massive advantage over a seasons racing. We are talking stock here but i am hearing some seriously impressive power figures coming out the BSB teams. This is certainly the way modern inline fours need to go the traditional bucket & shim has been at its limit for over a decade.
