There are a few guys who have attached a sidecar to a KLR650. A KLR boasts maybe 35hp, about half of what a GS850 is supposed to put out.
A Ural sidecar rig puts out maybe 40hp. There's a guy I see regularly around Indy who's towing a sidecar with a Honda 600 shadow (also about 40hp).
So I suppose the question is more what your criteria for "enough" speed and power are.
The KLR650 and Ural sidecar rigs are not much fun on an interstate highway at 80mph, and may even not be able to attain 80mph. They seem to work OK everywhere else.
Then again, interstates aren't the least bit of fun on any motorcycle in the first place.
