I might sell one of my two MXs, depends how much you want to spend. I'm pretty local to you, in Corona. I have upgraded suspension and a few minor tweaks to make it faster. One BIG advantage of buying from me is that I can fix just about anything that can break on the Alta; mechanical, battery or electronics, and I'd stand behind my bikes. But right now it's a sellers market. If you want to pay less than 8-11 grand for any good used Alta I suggest you wait for a couple years.
