The bike being too small for you or not is a very personal thing. It's all a matter of matching the bike to your riding style, ability, and the terrain you like. If the DR works for you - go with it!
Absolutely true. I REALLY like my 250, for a number of different reasons, the biggest one being that it's the right amount of bike for me at the stage I'm at. I don't ride the interestate, so I don't need more than 55mph. I don't have a ton of dirt experience, so when I drop it, I can pick it up by myself even when it's loaded, and it sips gas. I know plenty of guys that honestly need/can use more than a 250, but I'm not one of those guys yet... and I may never be. Honestly, the only time that I ever think I need/want a bigger bike is when I'm not on the thing, especially if I'm talking to other people. I'm slower than my friends on DRzs, but when we swap bikes, I get only marginally faster and still am barely keeping up with them. It's obviously me, not the bike, that is holding me back.
That said, I expect I'll be getting a DL650 in the next year or so, but the 250 will still be my bike of choice for anything more than FS roads. I just think that the DL would make a great tourer when riding with my more street oriented buddies.
To many great adventures! :sombrero:
