I mostly ride a street bike on the street, but my plated XR does see some pavement. I can ride out of my garage and it's 4.8 miles to some legal dirt (drinkwater). I can do 20 miles of pavement and hit the dirt in the Antelope valley.
It's come in VERY handy to be able to hit the pavement and head into town for some gas, etc. I've also done rides where the trail was very difficult and it ends at the pavement. It's either ride the street or double back over tough terrain.
Food and drink accessible from OHV is limited. Not so with a plate.
