The DL1000 is discontinued. Aside from adding ABS, the DL650 hasn't really had a major change, well, since it was introduced. And don't get me wrong; I love my '09 DL650A. But sometimes I could use a little more power. Not as much as a 1000 - let's split the difference.
Hey, Suzuki – Why not a DL800(A)? Both BMW and Triumph have jumped into this segment, and they're selling some motorcycles. Imagine the same displacement in the bulletproof (well, bullet-resistant) V-Strom engine. Add an inch or two in ground clearance if you can, but otherwise keep the ergonomics pretty much the same. The bigger engine would allow for a bigger generator, too - a popular request. And if you could put out a model that's already "off-road-ready," like the new Tiger 800XC, but a couple grand cheaper...
Sorry if this has already been discussed, but it seems like such an obvious idea to me... Hopefully, Suzuki is studying the Beemer and the Tiger, scribbling notes and murmuring in Japanese... "Yes... we can do this better, and cheaper..."
