I have done 2-up a few times with a total weight over 400lb (mostly me) and had 0 problem. Had plenty of power. If your doing a LOT of 2 up on the slab, consider getting the 1K. Its got a bit more grunt and has better gearing for highway speeds.
Also, consider this. The wee WILL do 2 up just fine. But if your going cross country, and plan on loading up big panners and a big trunk with lots of gear, thats a LOT of added weight and drag, and may be too much for the wee. Thats 1K territory.
