For Snakeboy
and all others thinking about a 250ccm dual sport bike as an overlander I can tell you the Honda CRF 250 L will be a suitable choice.
I even returned from a 3 month trip around Europe's south-east. My bike is now 11 month old (got it new in feb. 2015) and got ~30 000km on the clock.
It never had any problem, defect or broken part. Its oil consumption is nearly zero. The engine runs smooth and all-time-ready like at is first day.
The maintenance and consumption are on a minimum.
The only mods I did are classics: protectors at the handle bar and a bigger 11.3 Ltr fuel tank (Acerbis) which I purchased via internet in USA. It was simple to install - the stock fuel pump can be reused - and now range increased to 350km. But then its absolutely dry and you walk
I never touched the suspension or the engine. Some think about modifying the suspension but in my eyes that's not really necessary. If you're used to high performance suspension or your weight is very high - go for it.
I am just 76kg, 1,73m tall and used to old bikes far away from a modern KTM character (means my old japanese bikes run well, consume few oil and don't cost a lot at all)
The luggage question is really an issue but hey if you ride a small 250ccm bike why travelling with maximum luggage volume? I reduced camping gear and clothes plus small stuff to just 22kg in one medium sized and one small sized moto bag (both cheap) mounted on the bike's tail where you find 4 extended bolts for hooks/ lashings.
So a luggage rack is not a must-have here. Only if you want sidebags - it doesn't work without due to the non-symmetrical shape of the bike's tail.
In some countries like Romania I went offroad into forests, mud, gravel (once a mining site too) and the bike was a great choice! Because it's everywhere so handy and easy to ride but not uncomfortable on the long distances.
My personal record was 607km at one day in Germany and my butt was still okay afterwards. The next day I tried some easy offroad terrain. The third day I went back home again 607km.
What else?
At 2200m altitude the bike's power lowered as usual but the EFI still made the engine run absolutely normal.
Once in Romania I crashed into a car's back at low speed - nothing broke or bent.
I dropped the bike to each side once - nothing broke or bent.
The exhaust pipe is now super rusty due to the humid climate in northern Germany, my home, and the salted streets in winter time.
Except this there ain't no issues about the quality of this low-priced Honda made in Thailand. Pretty much bike for just 4.900 EURO.
Make your life easy! Ride an japanese lightweight dual sport!
