PS, lots of motorcycles have extreme buffeting issue. My Suzuki VStrom is horrible, as was my Harley RoadGlide. Other bikes not so bad. It's not just a Victory issue.
I presume you test rode a XC before buying? Not blaming you, but had you test ridden one, or looked on any of the forums you might have known of this issue. This has been known since 2010. I realized the issue on my 1st test ride, but loved the suspension so much I figured it was worth the risk.
Victory did fix the issue, their hard lowers, along with lowers by Cee Baileys, JTD and many others. Also, there are all kinds of windshield which will help. I added the factory hard lowers which are perfect, I admit changing to round crash bars was a non event for me.
I realize it is easy to buy a bike and expect 100% perfection. Doesn't usually happen, unfortunately. The good news is that there are so many fixes available
I do realize you are just ranting, and love the bike as nearly all of us do.
BTW, the JTB lowers look pretty good from what I have seen.
