How much does a Ten with standard sprockets rev at 100 km/h in fifth gear?

I bought my Ten last year second hand and from day one I felt it was very high geared. At 100 km/h GPS speed the rev counter says around 4000 rev/min in fifth gear. Is that standard ot have the previous owner changed sprockets to less teeth rear and/or more teeth in front?

Compared to other bikes I have owned 4000 revs at 100 km/h seems little.
I have owned a Transalp 600 that reved 4600-4700 at 100 km/h and a Honda Dominator 650 that reved approx the same 4600-4700 at 100 km/h.
Even the Triumph Tiger 955 revved at 4200-4300 at 100 km/h.

How much will changing the front to 14 or the rear to 47 change the rev at for example 100 km/h?
