I owned an R1200S for about 2.5 years. I own an S1000 now.
The R12S is a great bike. It is easy to ride very fast, it is more bike than you will be able to use on the track. You can also ride it 500 mile days if you choose to do so, I rode mine Seattle - Las Vegas and back.
They are a little goofy looking, no shortage on character. They didn't make many, they didn't sell many. I think the issue with sales was the price, they were very, very expensive new.
I recommend them!
