I am fortunate to have both a 2012 DL650 (with 68,000 miles) and a 2014 DL1000 which I purchased during a prior year model special sale.
The DL1000 isn't as smooth as the 650, but it has a lot more power and torque. The valve train is also a little noisier. Having said that, I am not complaining about the motor. At highway speeds, it feels a lot smoother and much more confortable (IMHO). I have done a saddle sore ride on each of the bikes and would rather use the bigger bike for those types of rides. Compared to the 650, the DL1000 has better suspension, traction control, a slipper clutch, and better instruments.
Wether the seat is more comfortable or not is a matter of opinion.
The DL1000 requires premium fuel (91 or higher octane). It also has given me 10 to 20 MPG less than the smaller bike.
Of course, this is just one person's opinion. Others may disagree.
