I don't think there's been a change on the Vegas, such as the forks that would be a reason a fairing for a 2010 wouldn't be the same. Guessing Memphis just hasn't updated their site or parts info.
If you don't care about a radio, and want to be able to pull it off in 10 seconds and feel the wind, Memphis batwing is the way to go for around $350, brackets and all, you get to pick the height of the shield. The factory gloss black finish goes just fine with the 8-ball, so you save the cost of paint. I've had mine for almost 2 yrs, no scratches, still glossy black. Just spray it with some Meguiar's quick detailer and wipe down with a microfiber cloth and you're bug free and shiny in no time.
