removing helmet holder

so here we go. probably the dumbest question ever asked on this thread.

I need to remove the rear helmet holder but it has that special screw with the star shape (sorry don't know the name in english)


does anybody know what size I need to buy for it to fit? Don't have the correct screw driver and don't want to buy a whole pack so would like just the correct size.

if anybody can help it would be great

thanks

Just checked and it's a T30 Torx

Not sure about anyone else, but mine was on there pretty damn tight, so I'd suggest either a T-handle style or a screwdriver, as those little 'L' shaped keys might be tough to get the torque on it you need to make it budge.

Yamaha gets pretty happy with the red loc-tite on bolts like that. Mine came off easy but def make sure you have the right size bit.
