I only said "close to the centerline" because I've read here that it may not be exactly on centerline with the BB shaft.
But I do stand by my point, and that was that it's close enough to not make a difference in belt tension when the swingarm is up or down from ride height.
Sorry Dan wasn't criticising your post, just making a point regarding accuracy of centre line alignment.
It seems likely that MMC did originally intend the BB box to be accurately aligned with swing arm pivots since with a clean design sheet there would be little credence in not doing so. As production changes have been made though, particularly the retro and production isolastic mountings, then maybe a small amount of mis-alignment has crept in, hence Laurens findings.
