Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
TSB-2009-007
APRILIA (PIAGGIO USA) MOTORCYCLE: WHILE DRIVING, HOT EXHAUST GASES FROM THE EXHAUST PIPE MAY BLOW DIRECTLY ONTO THE RIGHT REAR TURN SIGNAL. IN SOME CASES THE EXHAUST GASES CAN MELT OR DEFORM THE RIGHT REAR TURN SIGNAL. *PE
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
