I'm sure you've found the 690 is a monster compared to the klr. But it's still not a very good street bike. And it's really too heavy to be a good dirtbike. What you really needed was a 450EXC or 530EXC and a Versys.
The Versys does street exceedingly well. It's fast and light, plenty of power, and it's cheap to buy and run. Lots of accessories for it to make it do exactly what you want.
I would really like to have more of an adventure bike, but none of them make a very good dirtbike. I was really tempted with the 690, and the new Husky TE630. Niether one is a very good streetbike. And unfortunately in any one ride one might find conditions suited better to either end of the spectrum. In other words, it's easy for people to say 'just get a good dirtbike' or just get a good street bike that will go in the dirt. But if you're on your good dirtbike they are horrible for any long distance hiway running. And any bike that weighs 400 pounds or more is horrible for offroading. BMW thinks they've captured the ideal in the GS...gee, a 550lb dirtbike??? Not for me. Or Ducati - the ideal adventure bike (mulitstrada) but again, who would take a fancy $20K streetbike into the woods?
So, everything is a tradeoff. Each rider has to decide what his priorities are and then buy or build to suit. The Versys has a loyal following as it does what it was desinged for and does it very well.
The KLR? Well, the people that like those things are just not into performance. Which is fine. Some of the hard core adventure crowd are not into getting anywhere in a big hurry, they just want to get there eventually. For most of the rest of the riders they are looking for performance and fun, as well as being able to 'get there' eventually.
If you like the adventure part of the KLR/690 perhaps you need to be considering the new Tiger 800 or a F800GS. Both will do street pretty good, and be able to venture offroad on mild trails. They are both more well suited for the latter than the Versys - it's really a 'standard' street bike, nothing more. Yes, some have modified them to be better for off-pavement, but they are the first to admit they are not a dirtbike, and all those mods make them perform less on-road. More compomises there.
If you're keeping your 690 and want a streetbike, the Versys is excellent. After a year of ownership I would do it all over again, it's that good. Eventually I will probably replace my KTM250 with a plated 450. I'll have the best of all worlds then, in my opinion.
