These sequential indicators are fantastic but were difficult to fit on a 1260S Grand Tour. My advice is to strap up the rear underparts with a bungee before you take out 6 bolts, remove number plate and hanger, then remove the rear seat and take out four bolts. This drops the rear light into your bungee. Three torx bolts release the rear light so you can get at the indicators. I had to file some width off the top and bottom plastic halves to snugly fit these evotech performance indicators into place so the clam shells closed properly. Button it all back up in reverse order and don’t forget to blue thread lock each bolt. Then enjoy just how cool these indicators look. They are so cool.
