That is very true. Right now we have a HUGE group of aging baby boomers that manufacturers will need to consider though. It may be that a lot of potential buyers for the new GS want easier maintenance and more simplicity. If someone comes out with that product it may be a success just based on who the largest chunk of buyers may be. I've done maintenance on motorcycles in parking lots in 3rd world countries. Ease of maintenance and being able to easily carry the tools that I need to do it are a big deal for me, as I suspect it is for others. Can you imagine the difficulty in getting the right size shim to adjust your valves in some parts of the world? Some dealers don't even carry all of the possible sizes. There are dealers like South Sound BMW that are well versed in getting parts shipped to about anyplace in the world. I've had them ship parts all over the place and eventually almost always got them. Delays weren't their fault, it can take time for even small parts to clear customs and actually get to you. A real shocker is that comparatively speaking the US postal service is pretty good, there can and will be times that you never do get the parts and need to order them again because they will become lost in some 3rd world countries "system". On a bike like a Super Tenere with 26k mile valve adjustment intervals it's probably not quite as big of a deal. Unless a new liquid cooled boxer has much longer valve adjustment intervals though it will probably still be an issue for some folks. In my humble opinion, my 07 GSA makes enough power and gets good enough fuel economy. If I couldn't own a GS of that generation I'd be a lot more likely to go with an older version than one of the newer ones.
