I found these settings work for me:
1, Wind preload nuts (14mm spanner) fully anti clockwise to set the springs at their softest setting.
2, Wind the rebound damping screws fully clockwise and then back them off anti clockwise 1 or 2 clicks.
These settings reflect the fact that the front springs seem too hard, and the rebound damping too weak. The logic being that the softer spring setting allows the spring to ride the bumps and the rebound damping is near max to stop the spring returning to its
normal postion. This stops the harsh feeling from the front end.
1, Wind preload hand wheel fully clockwise and then back off 5 clicks anti clockwise for solo and 3 clicks two up (1-2 clicks with full luggage etc).
2. With a very stubby flat blade screw driver, screw the rebound adjuster screw fully clockwise. then back off by 3/4 of a turn anti clockwise.
All this takes about 10 minutes.
These settings make the back end of the bike sit up and slightly and transforms the handling in all situations.
It is so easy to change these settings and you can easily put things back to stock (the settings are in the handbook).
If I hadn't adjusted mine I might well have been buying an aftermarket solution - as it is, they will do me.
Have fun! Enjoy your new bike
