I agree with the others too. The bike should do it fine. As long as its in good nick mechanically a puncture is small possibility. So get yourself a tyre pando and make sure your bike has a tool kit. Even if you cannot use it a passer by might be able to check a plug for you or tighten something coming loose. But lets not get carried away with "what if". As long as the bike is ok you should be fine.
The offers from KB'ers are great but if you want to be guaranteed of being able to get someone if you are in trouble in the middle of nowhere. Join the AA, they are pretty good at roadside assistance and you know they will always be available anywhere in the country. Just an idea!
Good luck!
On a Motorcycle you're penetrating distance, right along with the machine!! In a car you're just a spectator, the windshields like a TV!!
