KX was a rocker arm  as with Suzuki's Full Floater, first true rising rate linkage rear suspension was on the 82 Cobas MR-1. The works RM/KX 125's used in the All Japan Championships had rocker arm rear ends in 1980. CR 125 had the Pro-Link in 81

So first Uni-Trak & full floater are eligible for EVO then if they are non linkage ;)

Anything that doesn't directly connect one end of the shock to the swing arm, and the other end of the shock to the frame, surely has to be considered a linkage?

Vincent was just a mono, well they had two shocks under seat really. No linkage.

Definitely not a twin shock.
