That is set for Supermoto(supermotard)
Whichj is both jumps and dirt combined with a street coarse. Then if ya just want dirt, yeah u just change the tires, though suspension is a bit rough for hard jumping in dirt.
VERY bad ass bike and if the suspension is adjustable, which a bike like an aprilia id thin id would be, it may be the best do it all bike u can get.
What size is that?
