Cars with plastic-covered handlebars (PK XL2, T5, Cosa) still need M8 spacer nuts for mounting (see accessories). As one of the few mirror holders also suitable for the Vespa V50 models with round handlebars!
Fits for mirror mounting left and right.
Hole for mirror thread rod= Ø10mm
Note: The holder is not ground and polished on both sides.
If it is mounted on the left handlebar side, the unpolished adapter side looks upwards.
