I started riding / racing in the early 70's. When I moved up and purchased a Honda Ellsinore 74 CR250M, I was on top of the world. I was pretty competitive at the MX scene, but as time went on, I could not keep up with the long travel suspended bikes. The motor the Else, was not much different of modern smokers, it was just trying to keep the rear wheel on the ground. As time went on the jumps got bigger, and the long suspended bikes would just pull away.
Long story short, I loved the bike so much, that when I took a 25 year hiatus from riding, I just parked the bike.... I took her out of storage, drained the fuel, put fresh fuel in.... and she fired after 10 kicks... yes it barely ran with plugged jets, but it still ran... I cleaned her up and rode it for a few years before selling her to a vintage racer, and moved up to modern bike.
The power of the 99 KX250 I purchased was equal to or maybe a little less the the Else, but the suspenders.... wow what a difference.
Here is a pic of my beloved Elsie, when I sold it in 2005, it still had the original front tire, and I still had the original exhaust system.
