I believe that Husky got it right with the 610 (for that time) the 630 was a plus and minus improvement. It was heavier, however both are not low maintenance machines. The 650 was imho not a real DS in the vein of the 610/630. The Japanese offerings are dated, heavy and uninspiring albeit they go forever. KTM's 690 is the best of the bunch and as Duggoey said, slight improvements to the stock seat, slighlty softer suspension and stock carry racks and it is exactly what Husky should produce.
+1 to ghte and duggoey. The 610 hit a sweetspot IMHO, and the 630/650 moved away from that. For my purposes I'd rather have less weight and less power than the 690 offers. That said, the 690 is the best now available. It is $$$, though. And orange. And it has a few of its own maintenance quirks, a tail that needs reinforcing to carry luggage, expensive parts, and limited fuel tank options. My friend owns a 690 and he was impressed by the the 701 concept's larger-looking tank. Here's wondering what the future holds.
