Yeah, I had no idea these bikes even had variable valve timing! It's so widely known on bikes like the VFR with VTEC (good or bad, you decide) but I didn't know about this.
On a related note: Anyone see the VVT system on the new GSXR? It's a mechanical system using a centrifugal flyball setup inside the intake camshaft sprocket.
