sell the KDX ?

Ride what you like. I do ride the occasional MX track, in fact my practice riding area on my property in a light-duty MX track. I prefer to ride snotty trails so the KDX is a good choice for me.

I like the way the KDX delivers its power to the ground. No, it can’t keep up with a true MX bike but at 40 years old I’m not sure that I want to keep up. A friend of mine has a YZ250 that I love riding, but it does wear me out.

The truth is one bike just isn’t enough! This winter I’m sure that I’ll be rebuilding a KX or YZ 250 basket case that has yet to be found. New bikes are nice but my philosophy is to spend less on my bikes but own more of them.

If the KDX is letting you down, you might want to try and upgrade the suspension and exhaust system. It will make a huge difference in the bike, however it will NEVER be a MX bike. Do you need a great MX bike or just a very good one?

Yes, I have about 500 hours on it.

There are plenty of them on the used market. Good examples sell for around $70,000 to $80,000. An older (5 years and older) RV6 can be had for $50,000 to $60,000.

Without a doubt, the RV series of aircraft are the best flying aircraft in the sky. Once you fly one its hard to go back to anything else.

On the original note, Keep the KDX and buy a lightly used MX bike. You can probably get a 2000 KX125 for $2000 if you shop arond a little. You can spend all the money in the world on the KDX trying to make it a MX bike, but its just not the right tool for the job.
