Welcome to the forum ST:smile_big:
And yes TR, I do have info and comments on his question but don't have enough real info to offer anything other than generic ideas:smile:
Both of your examples are fantastic means of travel and are great for a not to lengthy or high speed commute but work extremely well and frugally in the City and rural areas.
If you plan to be in a lot of stop and go city traffic, then the fully automatic Burgman 200 is ideal AND AND AND, there is a large storage area under the seat to carry your Laptop, Phone, lunch, raincoat and your weiner dog:wink2:
The TU250 is a great little proven bike but does require you to manually shift the trans. It is also great in the city and rural areas and gets incredible fuel mileage BUT BUT BUT, there is no storage at all for your stuff.
I absolutely love Scooter's and have had lots of them, just for the fun and comfort factor and still have a Burgman 650 in the stable.
Both are about equal in acceleration, cruising ability, fuel mileage and top speed.
Routine maintenance is easy on both, such as oil and filter changes but---the TU250's engine is right out in the open making it super easy to work on if need be.
Hope this helps!
