The CRF230L is probably not the freeway cruiser you would have hoped. 55 to 60-mph, sure. Much more and she is going to run out of steam by comparison to the mighty Yamaha WR 250X.
FI makes for quick starts no matter the temperature or barometric pressure. In addition, if you are one to travel over a wide ranging elevation profile, FI automatically adjusts the F/A mixture for a given pressure or altitude. A carb'ed bike will start to run like "****" w/out a jet change.
As a runabout, the CRF230L is fantastic but Honda raised the price in the middle of the recession to beyond that of the Kawasaki KLX250SF IIRC and that is some tough company to be going up against with a higher price and somewhat out of date technology. Standard fork tubes and not as competitive on the performance front for example.
I would also look at the all-new 2011 Honda CBR250R which includes not only a competitive FI 249 cc engine but available ABS, a first for the segment. It is also available at a much more competitive price tag at $3,999 to start. It will not be as comfortable given the sport form factor by comparison to the Supermotards or Dual sports but I would love to try one out and even add two teeth to the front and maybe drop two in the rear to make it even more fuel efficient.
I hope that helped and Good Luck with whatever bike you decide to buy. There are a lot of good ones in the 250cc realm so take your time and match the bike to suit your needs. Low mileage used ones can be picked up for a song as well
