As I said, there are educated professionals who say it doesn't, and neither does the previous generation of aluminum framed YZ450's, for that matter.
It's interesting that so many people can be given a gizmo of some sort and immediately notice the profound effect it has (even if it has none at all), whereas when something like a revalve, which remains a foggy, abstract concept to many, is done, they don't see the difference as certainly. People believe the thing they can see more readily than that which they can't, especially if they don't entirely understand either one.
Im talking about guys with hundreds of hours of testing with just this bike. That say it needs it. Why would some of the fastest guys on earth on this bike run this gizmo then? Im confused. Again I think it depends on your speed
Gray you proabably wouldnt notice
