Hello

Inspired by all the stories and videos you can find online, i decided to get on a unpaid leave off work in 2019 and the company even said yes
My situation right now is that i am getting my drivers license for motorcycles in Germany and i want to buy a bike in autumn (so within the next 4 months i guess). I don't have the license yet so i can't test some bikes but i just use google searches many many many times and i am simply overwhelmed by the huge selection of motorcycles on the market.
So some basic informations:
I am male, 26 years young and 1,78metres tall so im not really big, which could be a problem for big adventure bikes.
I plan to drive from Germany to Tiflis (Georgia) within 2-3 Months and avoid any highways. I totally expect parts with bad road conditions and offroad parts, i guess an enduro or travelenduro or the newer term "Adventure Bike" is the right thing to get. Anyway if i enjoyed it till there im totally open to go further since nepal is definitely on my bucket list as well as china (which is hard to reach with my own motorcycle due to the strict laws for foreign vehicles there).
I successfully traveled from north vietnam to the south and throu a few islands in Indonesia (Bali and Lombok) with a scooter and i loved it, this time whatsoever i want a real bike
One of the biggest worries i have is the weight, i definitely want a light bike, around 150 to 190KG. And i also am afraid of newer bikes with alot of digital or electronical technologies in it. What i also want is ABS, im not even sure why but i just think it will be a good idea to have it!
I found alot of maybe good bikes, then i find another opinion and think "nah maybe that bike is not good at all".
Im kinda "stuck" to the Honda CRF250 Rally, Honda CB500X, Kawasaki Versys X-300 or even Versys 650, BMW GS800 or Suzuki V-Strom 650.
Those are all newer bikes tho, to avoid the problem with the newer technologies i kinda am worried that a defect can end my trip way 2 early.
Older bikes I've found are the Kawasaki KLR500 (90s) but without ABS, or the KLR650, KLE650 (older Versions), the Honda Transalp and and and.
WHAT are good suggestions? I kinda would like to get it down to 3 or maybe 4 bikes and then just rent the bikes and go on weekend trips with it before the summer ends. I will definitely test the bikes before i buy but i cant test 20 bikes
Any help for a new motorcycle friend?
