How do youTake the seat off on a 2001 BMW k1200LS motorcycle?

There is no such BMW motorcycle as a "K1200LS." There is a K1200LT and a K1200RS. Is it one of those?

The bike is a R1100

There are 4 or 5 R1100's. The R1100R,RS,RT,S,GS. All are R1100's but have very different seat removal procedures.
