Mick Doohan's Motocoaster Dreamworld.

(Film link)

From roller-coaster.com.au:

"Mick Doohan's Motocoaster takes riders from 0-72km/hr in a few short seconds by way of a hydraulic system that powers 46 rubber tyres along the launch track, the second of its kind in the world. Designed for enjoyment by families as well as thrill seekers, the coaster is best described as an enjoyable experience rather than an adrenalin-pumping thrill ride. Dreamworld has been emphasising that the ride is above all safe and well-suited to families.

It is the first motorcycle roller coaster to come from Swiss manufacturer Intamin, featuring full-sized replica 500CC bikes, as well as two sidecar seats at the rear of each of the two trains that allow riders as short as 110cm (44") tall to ride with supervision. Riders must be 130cm (51") to ride in the other 14 motorcycle seats.

The 605m coaster is the first of its kind in the country. Other motorcycle coasters built by other roller coaster companies such as Vekoma exist overseas."
