Mason, a close friend of the world's fastest man Usain Bolt, crashed along the Palisadoes main road in Kingston on Thursday morning.
Reports claim Mason, who partied with Bolt in London in August 2016, had been on a night out before the crash.
He was 34 years old.
The Jamaica Constabulary Force (JCF) confirmed Mason's death on its Twitter page.
The JCF said in a statement that Mason apparently lost control of his Honda motorcyle and died on the spot.
Prime Minister Andrew Holness tweeted: "Our sincere condolences to the entire sporting fraternity."
Mason set a Jamaican record of 2.34 metres to win the Pan American Games gold in 2003.
He won silver and bronze medals at the World Junior Championships in 2000 and 2002 respectively, the latter event held in his hometown of Kingston.
Mason, in 2006, switched allegiance to Great Britain based on his father's nationality and went on to win silver in the high jump at the 2008 Beijing Olympic Games.
The former Wolmer’s Boys' High School student, in 2004, cleared 2.25 metres to win bronze at the 2004 IAAF World Indoor Championships.
