Hi, I dont know about the os55 or ys 56 but I have a BNIB TT Redline 53 which I know will fit the Extreme 50. PM me if you would be interested in having it.

They should all fit fine. When you decide which one, choose a pipe for that.

hi thanks, i was not sure on the novarossi 57 as i like the look off is but do not really no much about it, i have heard the os 55 still has bearing issues, i just do not want to buy one and it does not fit
