Police have reopened a stretch of Hyde Park Road after a motorcyclist hit a wall.
The 21-year-old man was taken to Leeds General Infirmary with a head injury.
West Yorkshire Police were called at 12.14pm to reports of a man having fallen off his motorcycle.
A green dirt bike remains at the scene.
It was initially thought that the man's injuries could be life-threatening, but a police spokesman said they are now considered non life-threatening.
There were no other vehicles involved.
A stretch of road by Woodhouse Moor was cordoned off while police continue their investigation.
The road reopened just before 3pm.
