Hi all
Thanks everyone, I have learnt a lot from the chat on this thread. I replaced the swingarm at Christmas and have now done a few rides .... and I really like it.
I sourced a 2018 swingarm and required extra bits from France and with airfreight it was cheaper than buying one locally in Australia,,,. The swingarm is 89mm longer, the linkages are the same but the linkage mount on the swingarm is 5mm wider. Beyond a 12 link longer chain the only other adjustment was to wind on 4mm more rear pre-load on my Mupo GT1 shock with 11.5k spring to get a similar rider sag setting.
It tracks through corners better, absobs bumps more easily (our roads are even more shite after record rains) and I can wind on power earlier and hold my line out of corners. It was initially less agile tipping into the corner but that changed when I added the 4th mm of preload and it is now close to what it was with the standard swingarm.
I am now very, very happy with my squat.
Cheers
Stephen
