Wife used to commute on her 640 Adv (later converted to a 640E front fairing for that dirtbike on 'roids feel) for years. Can't image the 690 is less sophisticated ; > She now runs an F800R, but same commute though - app. 90km 1-way if highway (rarely) and 110km if takes twisty 2-lane (99.99% of time).
The 690 is certainly better offroad than any drz. I've done OBCDR for 8 days on it carrying everything, with 3 other riders, 2 of which also bought 690's (and also amateur racers), the other was a retired pro that picked an rxv. We all found it the perfect long distance light adventure bike. It does ride tall which is a turn off for shorter riders.
Something that's not mentioned much is the rather narrow turn radius. Being a short rider (5'5") and the 690 being heavy compared to other dirt bikes I definitely struggle in the tight stuff. show shallow steering angle doesn't help much but most stuff is still doable but you'll be working harder than other guys.
We went to great length to discover and fashion the best touring mods and short rider adventure touring hacks. KTM 690 Enduro R Short rider hacks are a must. In my opinion it is the best lightweight adventure motorcycle option on the market but it's tall. While KTM adventure touring is usually a phrase reserved for the larger brothers and sisters of the KTM 690 I have discovered the 690
XKWd.
