. Probably the tires. On pavement, skinnier and harder tires have less rolling resistance.

so i should find tires like on my old bike and pump up my tires to 75psi?
. If you want to coast as far as possible. It's gonna be a rough ride and not worth a flip in the dirt, though.

how's that?
. The "balloon" tires on a dirt bike help absorb a lot of shock (low pressure) and keep the tire on top of the dirt (wide footprint). A skinny tire will dig in.

not extremely skinny, like griping but not as much.
