Old School KTM gear

So i was at a yard sale in my town, and came across a guy selling some old motocross gear. He explained he bought the house years ago and the shed in the back was full of old moto gear. Among it was a set of Alpine Star tech 4's, the red white and blue rick johnson models. There were also a bunch of team honda 81 trophee des nations stickers. lastly were a few jerseys from a Sierrra Works KTM team, these are what i have never seen. i'll post pics when i get home later, but does anyone know any history of this team, i can't seem to find anything.
