The modern KLR has all the power for highway riding, but if you do a lot of it, I would swap chain rings so that your RPM will come down so you can get the most from it's already great MPG. It is also a big thumper, so vibration is present and made my hands go numb constantly. My crash bars vibrated between 3100 rpm and 3400 rpm, to the point that I almost filled them with sand, but that may have been a byproduct of those specific bars. It is also tall, wide, and heavy, like too tall and wide for a short bastard like me (5' 6") to ever really get comfortable on it, and damned heavy. However, it is old school simple and very easy to work on. Diagnosing issues is as easy as the TW. They are work horses, and will give you tens of thousands of trouble free miles if cared for. The few times I rode on dirt, fire roads and canal roads mostly, I always felt overwhelmed as it is tall and top heavy, and I personally wouldn't have tried any of the trails I have ridden on the TW, but that is just me. Unless you are a very experienced rider, or tall and strong enough to muscle the pig around, I would look for something else... unless the bulk of your riding is on pavement and/or you are doing really long distance rides. For the price though, compared to bikes with a similar spec, they are very attractive.
