Ok, so it is one of my fave youtube overland channels, and is more 4wd than bike based, but there is a ttr 250 on the holland track, this is part one, well worth a look, awesome production values showing one of Australia's roughest tracks.
'Overlanding in the outback, it's everyone's four wheel drive dream. We tackle the historic Holland Track in a convoy of 6 including a Landcruiser 200, Landrover Discovery, Toyota Prado, Nissan GU and GQ Patrols, and Yamaha TTR 250 trail bike!'
