I've just bought a Husqvarna TE630 (I know, not a proper dirt bike), but mainly on the basis that I was chasing an 'adventure' bike that didn't totally suck offroad. The epically wide ratio 6 speed box and large oil capacity and long service intervals are its main draw cards, though it actually has quite good suspension as well. Downside is its a lard arse for a dirtbike (149kg), but coming from a DRZ400SM, its actually not much heavier so I figure I can live with that. I wanted to be able to do some longer rides to escape Sydney on the weekend without having to go through the process of loading up a trailer and tow car, plus the concept of camping and travelling light still has some appeal to me.

All that said, I do see a cheap little ultralight 2 banger in my future when time, money and space allows; just so I have all spectrums covered.

If your looking at the big bike end and want something more dirt worthy, the Husaberg FE570 is a weapon but the price is up there and the maintenance is fairly intensive (15hr oil changes). Would have loved one, but couldn't justify the extra expense over the Husky for the type of requirements I had.
