I would love an adventure bike again... My bikes in my younger years were more dirt bike than road bike but were used on the road, The likes of the XR600's. Good fun bikes but I have got used to electric start these days and would use my DRZ400 on the road if I could...just for fun but rule its off road only (paperwork issues, never registered from new)
If I had the money a new KTM 1290 would be fun.... the lighter, smaller africa twin is a great bike though so I don't know which I would get, A good friend has the Africa twin and loves it, has done some pretty out of the way roads/tracks on it. My Brother has the DL1000 (Vstrom) and while he thinks its OK he only has it because was cheap, not even close to the other two mentioned on bad roads/dirt tracks, he has taken the KTM 1190 on this across country trip Link below and the 1290R is supposed to be a step up from that

So Africa twin is a likely contender...If I had the money

It is a shame I can't road register my dirt bike... 400 is a bit small but it would do for now, may just swap it for a 650 for now.. better gearing on the 650 for road use but the 400 goes as hard


More KTM adventure riding, the 2017 North Island ride..... One day I must do one of these
