Years ago, before there were four stoke motocross bikes, I had heard that the 125 class made better lap times than the 250 (two stroke) class.
It might have just been the amateure class.
Does anyone have any facts or comments on this?
Your responses remind me of watching the races at Englishtown, NJ. The 125s would come screaming by. The 250s almost as much. But the racers in the open class would barely touch the throttle by comparison and it seemed like they were going much slower.
I was reading a Dirt Bike Magazine from 1979 and it had thehorsepower ratings in their tests. The125s were around 21 and the 250s were around 31. I used to race the 125 and 250 amateur classin the early 1980s. After a seriousaccident, I stopped riding for 25 years. I got back into it about 5 years ago, just as a fun hobby with my kidsso I bought a 2007 CR125. From what Iread, this bike has around 32 horsepower. It’s been a long time since I rode a 250 two stroke (1981 KX250) so I really can’t remember how much power my old250s had, but ... could that be right… a 125now has the hp of a 250 back then?
Someone will know for sure, but I think its very possible. The technology that has been developed in the past 30 years in all types of motors including vehicles is impressive. Just look at the power a V-8 had back then and compare it to those of today, or even the high output V-6 motors in some of the sports cars.
Not a problem... glad you guys furthered the discussion. I've learned a lot.
At the end of the day, I would like to know if my current 2007 CR125 is as fast as my old 1981 KX250... probably because I'm wondering if I am too big (190) and old (47) to be riding a 125.
I really appreciate the feedback.
Mark, I just watched a video of me going off a 5' tall jump and I am bottoming out on the landing. I just went to Motosport and it looks like new springs front and back will run around $250. That's about half what I thought it would be. Looks like I have a winter project.
Coyotekiller, I have a 1982 XR100 that I ride in the backyard when I can't get to the track... it's the most fun you can have on a dirt bike on 1/3 of an acre.
Thanks to both of you!
I can respect that.
It's all a balance in life... mow the lawn vs. go ride.
But sometimes it's about compromises... use the XR to mow the lawn :-)
