Safe Speed for My 2007 Venture

[Davvid]

Canadian rider here and it is a lot slower here. I just got my 2012 Venture S and took out on the highway last week. I used to ride cruisers before and I always notice the buffeting when passing a semi on the opposite way on a two way road, I never experienced the kind of buffeting that a semi would give just being behind it before. Every time, I got behind a semi, there seemed to be so much buffeting going on. So I had to drop speed, change lane and then  over take it or if no opportunity arose just to drop speed and let it go away and then try to change lanes if possible. 

I did get it up to 140km ( I think it is 86 MPH. ) and it was purring beautifully. I do not have a trunk and only the fairing and the side trunks.
