I am posting first time. I ride Kawasaki ZZR1200. My wife says it is loud and she can tell when I come home by its deep vibrating sound a few minutes before I arrive, although it has stock exhaust and I always try to keep rpm as low as possible when I ride through my neighbourhood. I am wondering how quiet K1200S is with stock exhaust amoparing to ZZR1200 or BMW boxer like R1200ST. I have just stood by a few times R1150RS or R1200L went in a close distance and I felt they were quiet. I have not seen K1200S running so far. I went to the open house of BMW dealer recently but unfortunately weather was very bad and no test riding on that day. I mostly ride early morning in weekend, because this is only time that i have to ride. I do not wnat to bother other people who are enjoying late weekend morning in bed. I would appreciate any input.
