Q: Is this bike right for me?
A: Only an aged, bearded mystic could begin to answer that question without knowing more, but I'll try: no. Read on.
Q: Am I going to be comfortable on this bike?
A: Again, this depends on you. One way to find out is to sit on one. A better way is to ride one. But I'll try: no. These are not cruisers. Nor are they passenger cars. Sitting on the back of a small motorbike in a rainstorm, trying to keep an eye out for distracted, texting teenagers in oversized SUVs with one eye while watching for snarling dogs and car doors with the other is by no means "comfortable." It's actually the furthest thing from comfort. Sitting in the back of a Crown Vic with your wrists bound in sturdy bracelets, contemplating the upcoming 12 hour booking process while blood oozes from your lower lip is more comfortable than riding a TW200 in traffic, in the rain, after dusk.
Q: What about sitting while getting to the trails?
A: Wrong bike. This is why I think this might not be the bike for you. If you picturing yourself standing in the pegs, spending over half your time airborne, you are in the wrong part of the showroom and will be sorely disappointed when you get to "the hills."
Also, to get to your concerns about your height vs. seat height, let me assure you that yes you will look ridiculous. I am 6'2" and am glad I am already married, because I wouldn't be out bird-dogging chicks on a TW. The kind of woman who would jump on the back is the type you should avoid anyway, as her acne medication would doubtlessly ruin your jacket, and her substantial girth would bottom out your suspension. Your milage, as they say, may vary.
There is a reason why a KTM 650 is more expensive than a TW200, and it's not because everyone who buys one is an idiot. It's more bike. Here's a quick litmus test: If you picture yourself (or want pictures of yourself) on your bike with air under both tires, look elsewhere. You might enjoy the TW for a while, but will soon yearn for something bigger and faster.
