Hey Yaminator - I did a 4 day 700 mile trip around France and Belgium on my MT07 in November. It was bladdy awesome, despite being freezing cold and wet!!
Here are my tips:-
1. Decide what kind of trip it is. If you plan on doing a a bit of sightseeing, consider leaving the 1pc leather suit at home unless you know it's comfortable enough to walk around in. Also think about whether you intend to be riding at night to/from dinner etc and whether you'll want to be in full leathers or whether a pair of kevlar jeans might come in handy. Pack a leightweight rain suit too!
2. Accommodation - you can often reserve rooms on booking.com with free cancellation up until the day of arrival. Consider doing this to give you the flexibility to cancel should you decide to ride that bit further or have a longer stop elsewhere.
3. Tools - pack a reasonable toolkit in case of emergencies, including puncture plugs and mini air canisters. My battery went flat in Brugge and it was a nightmare trying to find somewhere to bump-start it. I'll be packing leads for my next trip! That said, there are some things a tool kit just can't fix, such as the blown head gasket my mates KTM suffered back in Dover, but that's another story!! I guess what I'm saying is, pack some essentials, but don't go overboard!
4. Look at getting specialist travel insurance. Most standard policies wont cover you for riding a bike above 125cc so if the worst were to happen and you needed to be, say, air lifted, it wouldn't be covered and you could be looking at a hefty bill. I got cover from Navigator Travel Insurance for £13. Also make sure you have an European Health Insurance Card (EHIC) which you can get for free. Also think about getting a European breakdown policy.
5. As bobh said above, make sure you have all relevant paperwork with you. You will need to read the rules for each country but it's likely to include your V5 (I took a copy of mine), insurance, licence and the little card I got with my SC Project exhaust which confirms it conforms to EU standards. This might be especially important for Germany who I hear can be quite strict. For France, I took spare bulbs and a breathalyser. I bought reflective stickers for my helmet but didn't put them on (figured I could apologise and put them on if stopped!). France are also very strict about speed cam warning alerts on Sat Navs and can impose hefty fines. We didn't get stopped at all and had absolutely no bother what so ever.
6. Again, as bobh says, give your bike a good going over before you leave. Check your tyres have enough tread, check their pressure, clean and lube your chain, check chain slack and adjust if necessary, check oil, coolant and brake fluid levels and it wouldn't hurt to give all the nuts and fixings a once over to make sure everything is on nice and tight.
Other than the flat battery, the MT handled the trip amazingly well. My bum was perfectly fine on the stock seat without a gel pad but I average around 1000 miles a month so my derriere might just be adjusted by now!
