This is the exact same thing i'm planning and coincidentally on the same bike however mine is not restricted.
That bike will be great for a road trip however on the motorways you will be in the slower lane or alternatively take the windy roads (more fun).
Remember its not an endurance test! He he.
You will need to check your insurance and break down cover to make sure before you go anywhere and you will need a an EHIC card (European Health Insurance card) which you can get from the post office.
Also I am telling to go and buy this months issue of RiDE bike magazine as it gives you tips for going to europe on 55 euros a day!!!
I got it and its great!!
Have an awesome time!!
Good luck!
