Not to worry, QWP; your BMW K1300GT's engine won't break or wear out before its time due to its unusually low gearing. As long as te engine is properly maintained and used with at least some degree of sanity, it should enjoy the same lifespan as it would if equipped with the BMW K1200GT's gearing.
At 128 my bike is turning about 7500 yes it is a bit like ridding a chainsaw but I wouldn't worry about 5000. I just worked out that my 1967 Mini Cooper S would have been turning 5500 at 128 kph or 80 mph.!

Officially the BMW K1300GT was recently in the BMW lineup replaced by the K1600GT which is currently sold for around 1.3 million THB. In Thailand you can still buy a K1300S, which is what we can call a sports-tourer and costs around 1 million THB.
I recently bought a new BMW K1300GT, previous I had a BMW K1200GT.
The gearing is much shorter on the K1300GT than it was on my K1200GT, so the engine speeds are much higher at comparable road speeds. For example, at 128 km/h, the K1300GT is running at around 5,000rpm, much like a sportsbike would. In spite of the bike having vastly more power and a larger displacement though, the fuel consumption has been excellent, around 18 kilometers per liter in varied riding conditions. Obviously, BMW had its reasons for doing this, and I can't say that I mind. But will this affect the longevity of the engine? I haven't heard of any such issues, but it sometimes pays to ask to comfort one's own paranoia.
