I have been unable to obtain any information from manufacturer on the Tmax 500 for 2006. The information I have found here has cemented the fact that I am going to trade the cruiser for one. The testcride on the weekend was awesome. Quick, comfortable, manoeverable, and so easy to ride! Can I confirm that Tmax 500 2006 series i nAustralia has a 16 litre tank? Yours in scootering.
