Bought two K75's one is an 1993 K75RT. The other is a 1995 K75. The previous owner took parts from the RT to make a fairing for the 95 K75 that didn't have a fairing. The title on the 1995 says it is a K75. How can I determine if the 95 K75 is a plain K75 or a K75S? BMW shop says they can't determine anything with the VIN. The 95 does not have ABS.
