Way back when I used to go out to watch the short circuit racing at Action park in my home town of Maryborough, Qld. I was mainly a trailrider so didn't own a race bike, but when they introduced the trailbike class there I would rock out on my DR250 and have a go. The poor old DR was a bit slow, so I upgraded to a PE250. With this weapon I could almost keep up with the XR and XT500s and other such exotica. I had a ball and it wasn't long before I got me a proper racer, an 82 RM250Z that I raced dirt track with for about 5 years. I have to say I've never really been fond of motocross. I really enjoyed the trailriding and the occasional enduro, but by far the best fun of all was racing dirt track. Going through my old videos the other day and I found a tape of a race meeting at Action Park in about 1984. And of course, there's a couple of trailbike races on it.
So, here's some pretty poor fuzzy video of me and my PE250. Hard to see but I manage to hold down third for most of the race, trailing local A-Grader Danny Fredricksen and actually beating the wildman Stewart McCrae who was nicknamed Magoo for his wide open and failrly 'loose' riding style.
