■Notes on images
*Images are for illustration purposes only. Includes products with different sizes and colors. Product designs and specifications may change without notice. Please understand.

Precautions
*The master cylinder piston diameter of the compatible models listed above is 11mm. This product is a 12.7mm (1/2) type, so if you have normal calipers, the feel will change. Compared to normal where the feel was originally poor, it will be improved.
*It can be combined with the commonly known Yamanbo opposed 2-pot and Brembo 4-pot.
*For installation on the above scooters, the mirror is fixed to the switch box, so there is no problem with installation, but please check if you use the master cylinder's screw hole.
*The screw hole diameter for the rearview mirror is 8mm reverse thread.
