After 85 miles ride (US ones
) with the wife on the bike, she was pleased telling me that 1"1/4 makes a difference (added thickness to pillion.... what are you thinking about men
).
I added 20 clicks on preload from max anti-clockwise, and I could have added 25. It was ok for small bumps. Today her back is still OK.
Preload is adjustable to our weight which is great but, compression and rebound cannot be set to softer position at it is at max from factory settings.
