Triggered!

You don’t mean ‘stiffness’ you mean either preload or compression damping one presumes? You should never go to maximum on any of them unless you’ve eliminated other handling issues.


maximum preload then.
i thought id try that, then try minimum, just to see what difference the two extremes make.
the bike is a bit harsh at the back end over uneven surfaces.


Set the rider sag. You need to have it so the suspension sits at the top of the bottom 2/3rds of travel (or the bottom of the top 3rd, whichever way you prefer) with you sitting on the bike. It'll make a huge difference.

Then if the suspension feels too 'harsh' I'd say back off a click or two of compression damping.

I've attached a zip file with a PDF of a magazine article that explains suspension setup. It doesn't include high and low speed damping, but most bikes don't have this anyway.

thanks MarJay.
the suspension on my bike is very basic. the only adjustment available is the preload on the rear shocks.
id have to splash out on aftermarket stuff if i wanted any more adjustment.

I've learned that, annoyingly, the safety sensors (side-stand and/or dropped bike) will still allow the Aprilia to fire up for a few seconds => minute before cutting out.

Thus confusing the ignorant... (me Neutral ).
