Like Able say's mate, looks like you've bought the wrong bike.
The bike you have is basically a motocrosser ie you can only ride on MX tracks or private land if you have any. And clearly you don't.
My suggestion would be to sell it on and by a road legal enduro cost you about a grand for a semi decent one. You can then go where you like.
Green laning
MX tracks
Enduro's
Or just hooon about doing all three and even on the road.
Ofcourse the down side is Tax, Insurance and keeping it road legal. But thats a small price to pay for the fun you'll have.
Cheers
Jim.
