I have MC18 and the shock is blown, can't ride the bike as is. Finding new one has proven difficult so I'm researching the possibility of a swap from another machine or having a custom shock built, I'm sure Ohlins or Penske can do that.

Question for the experts is what is if any the difference between the MC18 and MC21/28 lower linkages?

I have +/-280mm eye to eye length and according to Ohlins website MC21 and MC 28 are 302mm, so If everything else is the same only thing I will have to do is shorten the shock, or order a CB900F shock which is 283mm for same style shock.

Any help appreciated
