Actually ended up going and looking at a 2011 model yesterday. Took it for a ride, just in a flat paddock, by man that was nice to ride, honestly just felt so light and would just go where you wanted it. Having owned Suzuki's which always handled nice, I have to say, I think the 150sx felt sharper than both of the yellow bikes I have owned.
This bike had 35 hours, and motor has never been opened. How long are most people getting out of a top end, and also bottom end. Considering making an offer, but want to try get it down a bit in price so I can at least do the top end for my own piece of mind.
I have to say though, considering that the top end is 35hrs old, it still had a surprising amount of power, so nice and snappy as well, boy I have missed that two stroke feel!
