The rider involved in the serious motorcycle crash at Warners Bay has died in hospital about 8.40am today (Monday 26 January 2015).

About 12.15am, a 29-year-old man was riding a Honda CBR250R motorcycle along King Street at Warners Bay.

As the motorcycle passed the intersection with Myall Street it has struck a kerb, mounted the footpath and travelled some distance before striking a sign post.

The driver was thrown from the machine onto the roadway and was discovered by other motorists who contacted police.

Officers from Lake Macquarie Local Area Command attended along with Ambulance Paramedics who conveyed the rider to John Hunter Hospital in a critical condition.

Investigators believe that alcohol and speed may have been factors in the crash and that the man was not licensed to ride motorcycles.

Inquiries into the incident continue and police have urged anyone that might have witnessed the incident to come forward.

A report is being prepared for the Coroner.
