Well after searching around with no luck for a different bottom bracket, i am selling this great WP yamaha race shock, its a three way shock, reb, comp and hig speed compression, adjustable shock length, 200 lbs spring i believe, thats what i was told when i got it, no leaks, no damage, shows little signs of use, it just wont mount up to my ninja 250r race bike project, it was from a 99-2002 yamaha r6 so it has two eyelet mounts, i believe some of the r1 shocks are the same, please check for fitment on your own, length, 300 -approx 312mm eye to eye. Asking $325 Thanks ross
