I successfully raced MX through high school in the 80's and a bit after. Started on 125's, ended on 250's. My last MX bike was a 1989 RM250. Sold it in 1991 and entirely distanced myself from the sport. Have owned and ridden a DRZ400S as a backcountry tour machine since 2006 with no interest in getting the rubber off the ground. I've seen plenty of MX bikes around though... and noticed how many 4 strokes MX bikes there are. Then, about a month ago, I began watching Youtube videos of MX racing. Boy, have things changed!
So many questions. First, why did 4 strokes catch on to the extent they did? Do many people race 2 strokes any more? Are there pro 2 stroke races? Do they mix 2 and 4 strokes together in races? What are the advantages and disadvantages of 4 strokes compared to two strokes?
Watching the Youtube vids has me reminiscing about the old days...has me wondering if at 50 yrs of age, I could still ride decently. These new MX machines look to be so smooth and agile. I'm guessing they are light years better now than my ol' 1989 RM250, yes?
Tell me all that you care to tell!
