What’s wrong with it?
The notice gives no hazard in a field of its own.
ON THE INVOLVED VEHICLES, ONE OR BOTH OF THE FRONT BRAKE CALIPER BOLTS MAY BREAK.
THIS COULD ALLOW THE BROKEN PORTION OF THE BOLT TO DRIFT INTO THE ADJACENT ROTATING WHEEL SPOKES.
SHOULD BOTH CALIPER BOLTS BREAK, THE INNER CALIPER HALF MAY BECOME DETACHED FROM THE MOTORCYCLE.

- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.

- How many have been returned or fixed isn’t in the notice.
