A few years ago, I rode my 2004 Kawasaki Concours home from work with a non-working clutch due to the same problem. I started it in neutral and with the help of a slight downgrade got it moving, then kicked it down to first. After that, it was easy to match the engine rpm with the gears and change gears while riding. There were 4 stop signs on the way home, but I was lucky and was able to roll through all of them without stopping, just had to downshift. A little risky but achievable. If I had to stop, I would have choked off the engine by braking and hopefully repeated the process. That bike weighed about 675 lbs, so it was no light weight. And it is the most top heavy bike on the road I'm sure with that 7.5 gallon gas tank up top.
