I've come a step closer to using the Tiger on my trip. There are two types of tyre available which will fit my bike. One is the Dunlop D616 which is aimed at slightly off road, 75/25. The other is the MT60's I think they're called. They are fitted to the Ducatti Multistrada and I'ver been told, are OK off -road.
I might try these out in Perth first $550 a set.
I'm also planning a trip to Europe this year to check out my bike and make sure all is well. Going over to Germany for a week, looking forward to it.
