I have a GPR damper originally for a 600rr , mounting kit altered to feat a 636 , for sale !
It was used on my stunt bike for a year only while doing fast endos or 1 handed endos so really it was used a couple of times a week.
It is in mint condition , black in color and V1 version , older FAT ones.
works GREAT !

250 with or without the kit

they sell for 495 on site or 440-480 on ebay.
