Purchase advice: Used travel enduro for big people wanted (max. 8.000 €)

Hello together, as a photographer I am a lot on the road (and out of passion) in the Nordic countries like Iceland and Norway and after the last years with off-road cars and also ATV/Quad got more and more craving for a motorcycle and last summer then finally catch up with the driver’s license (A unlimited). I am now looking for a machine for 75% road and 25% terrain. In Iceland it is often coarser gravel roads. Hardcore terrain is not really (with me) present . The focus is clearly on long and comfortable travel and a lot of luggage should also be included. Therefore, I fit well into the scheme of the travel duos. However, I grew at 2 meters rather large, which is not sooo problematic in the category of motorcycles, as I thought. The GS 800 (without a low seat) was very suitable and drove nicely. However, I do not know whether this is sufficient for me in the long term. Therefore, the 1200 would perhaps already be a nice number. 1200 GS Adventure was a bit too “thick”, looking for something slimmer. I will put the thing in Iceland often in the dirt … I know the slopes and their pitfalls (sand!) now well enough… Now the question arises to me, what is there besides the BMW GS universe still for brands and model that could fit for a large Viking? I am not very demanding in terms of design. My budget without accessories is 8,000 EUR and I am looking for something z Uverlässige and with the most important safety features and definitely ABS. I’m not necessarily the screwdriver – the machine should therefore not be too exotic. Thank you in advance! Greetings Jan
