What they said.
I like the versatility of mine. With the 18L tank & my lil homemade windscreen its a capable tourer & functionally not much different to an Adv. (I'm gunna get a comfort seat too, they're cheap)
For the dirt it's off with the windscreen & mirrors, on with the 12L tank & knobblies (& 14T front sprocket if the going is tight) & it's a capable, if slightly heavy, dirtbike.
A lighter end can & a rejet to suit is nice to have & gives a bit more pep, but for the average rider there aren't any
essential mods that have to be done.
Here's some of our recent travels:
