D on RR

I have Scotts damper in a great shape few months old it was on my brothers 929 its complite kit just missing a triple tree nut (left it on a bike when bike was sold) you can get those from Scotts for $16. He never did any stunts on his bike so damper has not been abused.It will work on 954 as well i have same thing on my 954.Looking to get $250 for everything.
