Tributes have been paid to one of the motorcyclists killed in a collision on a country road in Oldham.
Both bikers suffered fatal injuries in the accident in Delph Road, not far from its junction with Wham Lane, on Saturday afternoon.
One of the victims has been named as 17-year-old Joseph Smith, "a gentle giant" from nearby Middleton.
It remains unclear how the pair came to collide and an investigation is under way. Police appealed for information.
Officers are yet to release the details of the other rider.
Joseph's family said he was a "very quiet, gentle giant who would do anything for anyone".
The former pupil of Middleton Technology School was about to start his second year on a plumbing course at Oldham College.
His mother, Suzanne, said: "I've had my baby robbed off me."
His father, Tom, added: "He meant the world to me, they all do. You never get over something like this.
"There is an emptiness. I will never be the same again."
He leaves his parents, brother Tom, 21, and two sisters, Emma, 23, and 25-year-old Amy.
