I am going to do my best to translate some news items from Motorrad magazine on-line web pages.
Re: The drive shaft inspection recall. As GS and GSAs have much more suspension movement and are often used in wetter/muddier conditions, they are move likely to accumulate water in the shaft housing leading to wear. Authority RTs are reckoned to have a similar heavy duty cycle as they are often driven straight on and off kerbs. Such a failure is not considered likely on civilian RTs. The wheel is removed and a measuring disc is inserted in its place - test are run over various shaft angles and motor revs. If everything is within spec no action is required. If not then a detailed inspection of various parts is undertaken. If required, the fix is to drill a hole for a one-way vent near a CV joint to allow moisture and water to escape.
Re: Gearbox input shaft recall. Machines that undergo violent variations between engine and rear wheel speed can occassionaly experience a gearbox input shaft breakage. This would happen after long off-road/enduro type jumps on the GS or driving on and off a kerb on an authority RT when the rear wheel leaves the ground. The fix will be a software update to the anti-slip (ASC/DTC) regulator to prevent large discrepancies in speed before the rear wheel touches down again.
Hopefully this will be sufficient information for most...
