1994 R1100GS towed in w/ a locked rear wheel. The bike could roll about 2 feet front or rear, the engine ran fine but disengaging the clutch stalled the engine. Further dis-assembly revealed a broken front universal joint @ only 42,000 miles!!! Since the driveshaft is $700 and I would suggest replacing the clutch @ this time, this will probably not be an inexpensive repair.
