Got here a pair of HONDA XL MIRRORS that l purchased to install on my 86 XR600. When riding up at Hollister, l would tell the son to once in awhile, to hit that little button there by his left thumb, known as the horn button to let me know he is still behind me riding, and didnt crash, was the reason l installed these onto a 100% dirtbike. Parting out the bike now, so can sell these separately. The right mirror just simply threads into all XR600 front brake master cylinders, now for the clutch side, l went and purchased a XL perch that does indeed, hold a mirror onto. Then the slot / groove was too thin for a XR600 clutch lever to fit into, l had to file down the clutch lever to fit into this XL perch!! Want to install these mirrors into your XR, you will need to find a perch on EBAY for a XL600 like l did............. perch went away on the bars l recently sold.
