http://m.dailytelegraph.com.au/news...ls-risk-disaster/story-fni0cx12-1226766423881 EVERY weekend - sometimes in the dead of night - groups of motorcycle riders meet secretly to organise "time trials'' that they film and post on websites, pushing themselves, their speedometers and the road toll to the limit. Police are aware of the groups, which have closed websites, and believe they are an increasing problem - and a factor behind a rise in NSW motorcycle deaths this year. "We take very seriously reports of riders purposely exceeding the speed limit on organised rides, and recording this behaviour on cameras attached to their helmets. They run a great risk not only to themselves but also other road users,'' NSW Police Traffic and Highway Patrol commander, Assistant Commissioner John Hartley, said. "Even more worrying, we are seeing cases where groups are posting this footage on social media - sometimes on our own Facebook site - in an attempt to popularise their behaviour. "Police will continue to review and investigate such poor riding behaviour, including the footage we're seeing online, and do everything in our power to prosecute those involved. Many group rides are undertaken in an organised, orderly and law-abiding fashion, but we're well aware of those who choose to break the law." There have been 64 motorcyclists killed this year on NSW roads, 10 more than last year. Earlier this month a 19-year-old man filmed his own death while wearing a Go-Pro camera on his helmet when he crashed in the Royal National Park. The Park is referred to as the "nasho'' run and is popular ride south of Sydney. The old Pacific Highway in the north and Wiseman's Ferry and Putty Rd in the west are also popular for organised weekend rides - and the sites of many fatal bike accidents. Some biker groups have regular "meet-ups'' in and around the city during the week. One group, called the Sydney Riders, congregates on Thursday nights and ride in a pack of anywhere from 20 to 50 all over the city. The Bike Club, SydneyMotorcyclists is another group and does regular night rides. NSW Motor Cycle Council spokesman Chris Burns condemned the behaviour of some groups, saying they did not represent the majority.
