It was well said earlier that the preferred bike all depends on the intended riding, but it also depends on what you enjoy riding & seeing parked in your garage. After having a '91 DR650, '88 R100GS, '95 R100GSPD, '01 KTM 640ADV, '04 DRZ400S, & an '07 KTM 525EXC, & currently an '06 HP2 Enduro(chosen over the F800GS) & '05 DR650, I must honestly say my '05 DR650 is the best yet. No sexy European build or components & I've not tried the 'Berg or Husky yet, but...
I would've never
guessed how smooth running, lightweight (300 lbs), agile, reliable, well designed, stable, simple to maintain, & generally capable it is on everything. There's good reason why the DR650 thread in ADVR Thumpers is the largest & guys routinely report 30-40-50K without ever seeing a dealer but for tires. Lately I'm just riding narrow, windy country roads & fire roads, so the DR fits that requirement & it is a blast. If I was slabbing it or doing lots of single track, my requirements would be different, but I'd still keep the DR.
For under $3-4K you can find a very low mileage, clean, '04-'09 & put an IMS 5.2 gal tank, Sargent seat, laminar windscreen, etc (see my posts if interested), & you have a bike that will go anywhere. I'd choose this as an RTW bike over any other NA available bike, hands down. Just my .2 cents worth Gents.
