FIRST FULL WEEK IN AUGUST>>>>>>> That is when they Unvail the NEW bikes(Sturgis week).
Sturgis week end START is the Normal time that HD cordinates Bikes at the HD dealers show room floors,,,, Starting for sale and view at the Exact First Day of Sturgis..(weekend)
In the past, I have seen a few dealers get their bikes a week early but NO SALES until HD say so.. They even kept them in the back rooms UNTIL the official day....
