Speaking of security type bolts, I was mildly amused, but mostly annoyed, that when fitting the upper OEM Yamaha side case mounting brackets that the rear bolt was a T-50 Torx security/anti-tamper type. Stopped me cold on the installation until I could go to the store and purchase the correct bit the next day. The stores were all closed for the evening already when I discovered this. Yamaha should have made some mention of this in their instructions or included the correct bit so that I would not have gotten stuck unable to complete the installation - annoying.
I don't really see the point anyway. First, that bolt is pretty hard to access with the cases in place so unless the thief intends to steal the brackets, the security value is questionable. Second, it was a simple matter to purchase the correct bit at Lowe's or Sears. While on that I also question the value of the T-10 security screws inside the case that retain the locks. If the thief has access to these it's kinda too late right?
