De Carbon gas pressurized shock cavitation limit As a sanity check you can figure out the cavitation limit of a basic gas-shock from the gas pressure. With 190 psi on top of the 40 mm shock piston and vacuum on the back side the force on the shock piston is 370 lbf. Push the shock beyond that and the pressure drop across the piston sucks the back side to vacuum and that cavitates the shock. The shocks damping force curve shows the Tenere shock hits that 370 lbf damping force limit at shaft velocities around 30 in/sec. More-or-less inline with the chamber pressure plot showing the shock cavitates at that speed. De Carbon style gas shocks used in the Tenere, V-Strom, DR650 and KLR all suffer from a compression damping limit set by the shocks gas pressure. That 370 lbf compression damping limit happens at about the same point where the shim stack hits the backing washer so the whole thing blows up at the same time. The shock was well designed.
