The DR can be made a hell of a lot "snappier" pretty easily too. Just open up the intake and exhaust, then swap in a flat-slide pumper carb...like an FCR39 or a TM40. Gear it with 1-3 more teeth on the back sprocket when it's time for new cogs. It'll be considerably peppier than stock.
If you want to go even more drastic, you can add a big-bore or hi-comp piston, big-valve head, port and polish, and a stage 2 cam. 50+ WHP is getting more and more common on DR builds. Tuning the suspension can make the bike more responsive too.
Another plus...It's nice having the same model of bike on trips. You only really need 1 set of tools, and some spares don't have to be doubled either. You can also troubleshoot with a ready supply of known functioning parts.
