Sydney man dies after crashing speeding motorbike

The moment a speeding motor bike rider dies in a tragic crash on a suburban Sydney street has been captured on CCTV.

Marios Constantinou, 36, was on his Harley Davidson for the first time in two years on Wednesday when he lost control and slammed into the back of a ute on Old Kent Road in Greenacre.

The sickening moment was caught on a nearby property’s CCTV camera as children played in the yard.

Footage shows one resident dropping everything and running to the man’s aid, but it was too late.

‘Heard a massive loud bang, just ran out straight away, seen the guy,’ one witness told 7 News.

Paramedics arrived soon after but were unable to revive the man.

‘There was no pulse, we all tried, tried to help him but there was nothing we could do,’ a bystander said.

The speed limit on the quiet street is 50 km/h but residents believe the man was doing more than double that.

They are now pleading with road users to consider the dangers of speeding.
