The first thing I do when I suspect a scam is Google an unusual line in the posting. Usually these scammers just copy another post. Google "2013 Yamaha Raider SCL #491 of 500 made" and the first result is for another CL post for the same bike at $11,900: https://austin.craigslist.org/mcy/d/2013-yamaha-raider-scl-like/6381596885.html
. Yep, it's a scam. Sorry.
