The vstrom is lighter than the 502. Not sure how benelli managed to make the trk that heavy. If Chinese bikes are not out of your shopping list, can consider the CFmoto MT650.

Vstrom looks better, better engine. Bulletproof.

Don't go for the 390 ADV. Unless you are 5'10 you will find the 850mm seat height difficult. The single cyc will buzz your nuts off. Just buy a Dominar and save 70% if the only off road you will ever do is light gravel. Then get something bigger later after some seat time.

Can't go wrong with the CB500x. Prefect bike if you are content to have a bike that won't rip your arms off.

Again, all these ADVs, including the small cb500x, have seat height from 830mm. So unless you are 5'8 and above, it's going to be a tiptoe fest.

Curiously I've been on the highway with both the 390adv and the dominar. The Dominar is actually more stable at speed...less affected by wake from lorries and crosswind.
