Welcome. We can't get the official TW250 in the USA but we would probably all have them if we could. My suggestion would be to get the 250 with some platform riding boots. The TW200 would probably be great for your size since you are on the smaller side. The suspension would probably do you good and the engine would be much stronger than for us who are over 200 lbs. I love my TW200 as a scoot around town because it is so maneuverable and narrow. I have only ridden light trails and it has done everything I needed it to. Others will have more about its off road capabilities even though it only depends on what you are actually doing with it. Mine has been very reliable and I am happy with it.
