11) What is the life cycle of quad bikes in Australia? For example, on average how long do consumers use quad bikes before the vehicle is retired? How long might it take before the current stock of 380,000 quad bikes is replaced by new stock that satisfies requirements of a safety standard, if imposed?
Some bikes will be 20 years old and still going strong, so for 380,000 to be replaced with new models, could take some time!
A start would be to introduce a basic 'warrant of fitness' system, and any bike that is serviced by a dealer needs to pass this once a year - this could purge out a lot of older bikes and turn them into spare parts (features such as faulty brakes, rusty frames, damaged plastics etc etc that wouldn't be worth fixing, would 'write off' the bike as such)
