The photo was taken at the Australian Touratech event? Robin Box, is the Australian Touratech Distributor. He is also the owner of Safari Tanks. He owns a Terra. I presume that's his bike. (His main business is building canoes, so I presume they're his as well.)
If you want to call it that, but if that raft system breaks, it's his personal bike going into the pond, so he's putting his money where his mouth is (And I believe he bankrolled the Australian Touratech Event as well, so he was putting his money on the table first). We are actually quite fortunate in Australia. We have a relatively small population, and therefore a small market for motorcycles to start with, and an even smaller market for adventure bikes, but we are fortunate to have some of the best adventure bike accessory manufacturers there are. Safari building long range tanks, B&B building bullet proof bashplates, Andy Strapz building soft luggage systems and a myriad of other accessories and even a mob who design build and sell complete Rallye conversion kits for KTM690s if that's your weapon of choice. If a bit of product spruiking and self promotion keeps them all in business then let them go for it.
I fully agree, and of course I believe you have some of the best Adventure Biking country in the world, with great information exchange and excellent group cooperation all over OZ.
