I have a '13 SG with lowers, a stock seat, and a 7 inch Windvest shield. I'm 6' tall with a 34inch inseam, wear a full face modular helmet and get zero wind buffeting.

regards,

 

Having lowers and or the wind baffles on the front forks seems to be the answer. Mine is about to get both.

 

Took a 20 mile highway test ride with the fork wind deflectors and all upwind...GONE! I rode up to 75mph and nothing, no wind from under was hitting me just a nice calm air pocket.

Here are some pics, I don't think they look bad they almost blend in like they were installed from the factory.









I might still get a larger windshield as I can tell now that the under wind was eliminated, that the wind off the windshield is hitting me at eye level. But I'm very happy with this improvement!

 

good deal !
