Smooth as butter! The engage appears to looks more refined than what we have seen in the past... looks production ready.
...wait 169kmh = 105mph right? Holy shit! May be different when actually pushing the bikes weight though right?
Also, nice shoes, but the way things look you definitely would want to make sure they are tied and not have your shoe laces flapping in the wind, or im sure you would lose them. Hopefully the production version has some kind of chain guard there.
