Excellent point! I am with you 100%
A few years back GS and BMW forum groups were full of posts from riders in the line of "Why can't I reach top speed in the 6. gear?" Or, remember the O/D gear of the V-S DL1000? The very same complaint.
It must be my miss, I don't understand why someone needs to reach top speed in the 6. gear. Nobody ever gave a logical reason. In my world, if an engine is well capable of living with 5 gears - and the GS as well as the V-S 1000 engine are to a 100% - the 6. gear can positively be used for lowering touring / cruising rpm.
Unfortunately BMW gave in to stupidity. Billion flies like shit, so it should taste good ... Sorry for being so harsh, just my frank opinion.
