I am curious about 1 thing on the newer Concours, the windscreen with the vent...does that really make a big difference riding with the vent in open position(s)?
On the stock 2010-2014 windscreen, there is back pressure, but just raising it an inch relieves most of it.
For YOU maybe, but remember how little agreement there is on windshields, seats and bars.
Nothing but all the way down worked for me, with every windshield I tried except the Aeroflow...but that thing really flopped around and it was unsightly. I even tried the Madstad brackets.
I think of the 2015+ "mailbox" vent as more of just that, a vent. It allows more airflow for cooling that you can get without it.
That may be the way YOU think of it, but it works more for a back pressure vent than a cooling vent for ME. I generally ride with the screen all the way down, but in the very cold, the heavy rain, or to get some more quiet to talk on the phone, then I need it up and then the back pressure really kicks in for me. A half hour in the rain with the windshield up and my neck muscles were screaming at me.
I installed the new vented OEM windshield on my 2010 model and the vent is the only thing that has really helped with that when my shield is up. So yes, the vent is a big help, for ME, but for you Mikeb2411, I'm afraid we can only say maybe. With shields, seats and bars and even footpegs sometimes, it's a crap shoot as to what will work for you.
AHH I need to go to bed, Conrad will be getting up in an hour to get
it on with the Mrs on with his day, and I won't have had my first dream yet.
