The 37-year-old is believed to have died after his bike collided with a telegraph pole on the Dungonnell Road in Crumlin on Monday morning.
No other vehicle was involved. It brings the total number of people killed this year on Northern Ireland’s roads to 18.
A statement from the PSNI said: “Police are appealing to witnesses or anyone who noticed the silver Honda motorcycle travelling on the Dungonnell Road, Crumlin to contact them at Antrim on the non emergency number 101.”
