Alright, to those sitting on the edges of your seats, the total cost of repair (including £25 to rescue the thing from my driveway) was £313.00. I'm too pleased at having my scoot back to be too annoyed, although it's a chunk of change I certainly hadn't budgeted for when buying! I covered more than 500 miles on it this weekend, everything from motorway riding, to trundling around country lanes with my feet up, to tearing through oxfordshire in Sport mode chasing Honda Fireblades. I've also dropped it twice (once on each side for symmetry), which is the same number of times I've dropped my other motorcycles in the last 8 years of riding. It is very tall, but fortunately I was stationary at the time and damage was limited to very light scratches and scuffing.
Full disclosure, I did look at the Kymco, and if there were a dealer in this half of the country I would've considered them more seriously. They looked great when I saw them at EICMA, but seem to have the same UK presence as chinese scooters - zero dealers, zero support. A bent wire could happen to anyone, and I'm pleased that Yamaha have enough dealers that I was able to get it taken care of locally. I'm not going to comment on the Kymco because I've not ridden it, although I did read that the recall for the drive belt on the T-Max earlier this year was to change it to a thicker/wider/tougher one - possibly as a response to some of the issues you guys mentioned!
I did look at the Burgman 650 as well, but the weight and the lack of cruise control pushed me to the Yamaha. If you can find a Kymco to test-ride, I certainly wouldn't discourage it, but for now I'm back to very much enjoying my new (to me!) T-Max DX.
