Poor Trampas Parker never had the luck in the GP's. Had the skill for sure but he had the brad lacky syndrome (all but brads last part). USA riders never seemed to have the luck in the GPs
ca.1989 From Racer X-- "Trampas Parker went on to become the first American to win a 125cc world title that year; two years later he added the 250cc world title, making him the first American in GP history to ever take two world championships. And a few years after that, he won a 500cc GP, making him the only rider in U.S. MX history to do that. He should and will be in the Hall of Fame soon." That guy got me interested in KTMs along with the Enduro racers. the article http://racerxonline.com/2006/06/23/where-are-they-now-trampas-parker
I was talking about the 500's (hence the brad reference) A GP in 500's is not the title and hence the trifecta eluded him
There was a lot of great racing that year in the 500 class. I bought the whole series review video in some shop in Italy years ago. Unfortunately it's a VHS tape and they are formatted different and won't play in a US VHS player. All the commentary was in Italian...but it was pretty funny, after one of Parker's DNF's (I think the front end broke off his KTM) they stuck the camera in his face when he was walking off the track and he is just cussing up a storm in English...called his KTM an effin piece you know what.....!
