the 2011's are not as good as the 2012 and up. (hope I don't start an argument with someone for saying this).
2012 they made a few changes that made a big difference.
You can get a 2012 NEW (not demo) for around 12k. I've seen it somewhere here in California. Can't remember where.
15k is a rip off. First of all, it's 2 years old, USED.
Regardless of them saying it's NEW, it's used. It's been ridden. The breakin period has probably not been done properly on that bike.
I don't know you, but i'd hate to see you make a big mistake like this. PLEASE DONT BUY IT.
PM me if you would like I can help you find a 2012 with 3 miles (NEW) for around 12k... I'll dig around for you and help you if you are serious.
OK - i'm looking around. Can't find the 12k S1000rr I saw about 2 weeks ago.
But just to make a point. Brand new 2012
for less than 15k
