Dialing-in suspension

[Underground]

Changes to the front definately affect the rear,
After fitting intiminators to the Africa Twin alot of problems that I thought were rear problems diminished (although a new shock would be nice )
One interesting improvement was that even two up the rear doesnt crash down into those big hard edged potholes when I hit them at speed nearly as much as it did before

Ok so what's a high pressure for a knobbly ?.

Depends on the definition of knobbly, the bike and the terrain

MX/Enduro tyres, 20psi is pretty high; they are designed to work at more like 14psi but max permissible is low-30s. Spec for my EXC is 14psi fr/rr for off-road, and 22/29psi fr/rr on-road (same tyres, DOT enduros).

Adventure tyres can handle quite a bit more, since it is needed for higher speeds & loads.
