THE SOUND IS COMING FROM THE STORAGE COMPARTMENT.IT`S SO SPACIOUS THAT IT ACTS LIKE A LOUD SPEAKER FOR THE ENGINE.ACTUALLY I ENJOY IT,.IT SOUNDS GREAT WITH A GPR EXHAUST I RECENTLY PUT ON.NOTHING TO WORRY ABOUT.IF YOU HAVE 20/24CM NUMBER PLATE IT ALSO ´CRACKLES´,BUT CAN BE FIXXED BY PUTTING 2CM THICK ADHESIVE PAD OR TAPE BETWEEN THE PLATE AND THE FENDER.WORKED ON MINE.TIP!TO IMPROVE YOUR FRONT BRAKE CHANGE THE STANDARD TUBING WITH HIGH PRESSURE ONES.BETTER FEELING WITHOUT RISKING BLOCKING OF THE WHEEL.
