A council spokeswoman said it would endorse an urgent upgrade of the road surface and an audit of road signs in an attempt to cut crash rates.

A young woman remains in hospital with serious head injuries following a crash on Sir Bertram Stevens Drive on May 13.

It is believed the woman lost control of her motorcycle while riding over a pothole, causing her bike to flip over several times.

Readers bombarded the Leader website with comments following a story published in Thursday's edition that revealed 40percent of crashes in the Royal National Park last year involved motorcycles.

Most blamed the statistics on motorcyclists who used it as a ``speedway''.

Readers called for speed cameras and speed humps to be installed to slow down riders.

One reader said he was appalled by the attitude of most motorcyclists in the park.

``They overtake on blind corners, exceed the speed limit and have a blatant disregard for other road users,'' he said.

While some readers said reducing the speed limits in the park would save lives, others said fixing the roads would help accident rates drop.

``The problem is with the road condition,'' one reader said.

``Lowering speed limits will not help when the loss of traction is either leaves or a hard-to-see pothole.''

RTA crash statistics show there were 45 accidents in the park along Farnell Avenue, Audley Road, Sir Bertram Stevens Drive and McKell Avenue in 2007.

Out of those 45 crashes, 18 involved motorcycles.

Senior Sergeant Michael Simpson from the Sutherland Highway Patrol said police were aware of high number of motorcycle crashes in the park.

He said the area was heavily patrolled by police every Saturday and Sunday, when most of the accidents occurred.

``It's been an area high on the priority list for speed enforcement since 1998,'' he said.
