My bike seems to have an affinity for buell parts. The headlight, cowl, footpegs, and yes, hand guards
They arent as large as the Tiger, Vstom, etc guards but look nice and mount to the pivots for the clutch / brake levers which makes for a nice clean installation. A lot of the other styles out there rely on exposed handlebar surface in-board of the master cylinder. Therefore not possible with our bikes in stock configuration.
Regarding performance, they take the windblast off the hands quite well. Keep in mind my Sprint is naked, so the effect wont be as noticable with a full fairing bike.
I don't have any specific photos of the setup, but here's a few cropped images from a week or 2 ago.
