OK, here we go.
2004 ST1300, 18k, new to me last October. I have NO IDEA whether the shocks have ever been touched or modified.
What I “feel” is that they’re stiff in the sense that I feel minor road imperfections as controlled bouncing in the front.
Not a problem and the bike behaves well on the road and at speed.
This morning, I measured static and dynamic sag
Static sag, from shock unloaded to carrying just the weight of the bike = 1.4375 (1 7/16”) = 36.5mm
Dynamic sag, with my 200lb carcass and after bouncing and letting it settle, 1.75in = 44.5mm
static sag % of travel = 36.6 / 117 = 31.2%
Dynamic sag % = 44.5 / 117 = 38.0%
The old (SS+DS)/2 /travel is (36.5+44.5)/2 = 40.5 / 117 = 34.6%
Does this seem reasonable?
PRE-ANSWER caveats - I am NOT INTERESTED in “take everything apart and rebuild it yourself to get to know your bike.” I am interested in others’ readings and the % of total fork travel that seems to be normal.
