Hi All

Eight months into our RTW I'm back to the which bike debate. My F650GS is just a tad too heavy for me so I decided to sell it and get a lighter bike. The GS is great in many ways: hight, comfort..... But I am short and off road, this bike has proven a little heavy to have confidence and fun.
Now in India on a little Indian 220cc toss-around, my suspicions that I'd be having even more fun on a lighter bike, have been confirmed. I CAN ride on the GS, but I'm having twice as much fun on this 120kg bike!
So, a 100-120 kg GS or similar would be great, but I don't know of one (if you do, shout!).
I've been eyeing up the Yamaha TTR 250 (I particularly liked a 1993 model I've seen). Completely new to these bikes, I have a few questions:
- have there bikes changed much over the years, i.e. in seat hight, electronic complexity, carb vs electronic start, weight
- are spare parts (especially for the older models) widely availlable
- what modifications should I think about to get it travel ready (e.g. stronger suspension, frame reinforcement to carry luggage, front suspension, anything prone to break on these ones?
Any advice would be much appreciated!

Thanks!
