If you are liter bike type of rider, you will likely want the 1000. The 650 handles a little better and is much easier to ride, but it doesn't have the liter bike kick or low end torque. The 1000 is a better highway bike, although the 650 will do it just fine- just a little doggy at high speeds. I have a 1 tooth larger front sprocket on mine to give in a little longer legs... makes it feel less frantic and is better at highway speeds and above. Just keep in mind that 65 horsepower is just 65 horsepower. The flat torque curve makes it a very useable 65hp, but it's not going to charge out of corners like a more powerful bike. It's strange how different the two bikes feel (1000 and 650). The weight difference feels quite significant at slow speeds, and fast switchbacks. I like the lighter feel of the 650 better, and find it has enough motor for any riding I do. It's not as sharp a tool for twisties as my Triumph, of course, but it's VERY capable if you are a good rider; feels very planted (although some suspension work really makes it much better- fork brace, cartridge emulators), but takes more effort to turn in than a true sport bike. I have surprised quite a few people with what should have been much faster bikes. I took it to a track day at Beaverrun in PA, and in the beginner class I was constantly being held up in turns by guys on real sport bikes (that couldn't ride, obviously). The problem was, I could easily pass them in the tight areas, and they would blow by me on the straights, so I had to get around them again on each turn. The experience did not shame the bike at all in the handling department. I laid it over hanging off until the pegs were grinding hard, and it was as stable as could be... a lot of fun, too. I really don't think you will go wrong with either DL for what you are looking to do. If you want to sacrifice a little comfort and versatility, the SV is a great bike as well. The DL is a better do-it-all. If I had to give up one of my bikes, it would be the Speed Triple. I love it, but I love the DL more, if that tells you anything.
