There is no doubt there are difficulties getting stuff in remote locations, but with a bit of forward planning and creativity this can all be sorted out. Which parts not required for routine maintenance are really required on a bike? Your current situation is representative to that of people on a trip, but not having a network of friends locally, it's more difficult (not impossible) to arrange for things to get sent out.

Having read Horizons threads before I started doing my own bike trips I can't help but feel the reliability argument is over stated. As is the blend in, old is better, or old means being able to get local parts argument. That's not my experience at all. I've been fortunate enough to not need to search for parts, but every part that I needed was not locally available, and that was on an old bike.
I'm six feet, blue eyed and blond. Including facial hair. The Pakistanis thought that was piss funny. I've got no hope blending in. Luggage doesn't help either. But I think remote communities would roll out to see what rolled in regardless who you are. You are a foreigner to their community, not just their country. Being dirty can help.

The tools required on BM's and I guess Euro bikes in general are ridiculous, I agree. It's a breath of fresh air, having moved to a WRR from a F650, to see how simple things are done on the other side of the world. Even with a higher level of technology used. My tool and spares kit is tiny now. A motion pro tool kit takes care of just about anything. I hope CCM take this into consideration.

The fun factor is different for everyone. Generally, most people on this forum, myself included, start off with no or nearly no off road experience. So a 'get by on anything and enjoy the smell of the flowers' approach is more common. The more you do these adventure rides, locally or abroad, you tend to get better at it. With that comes a divide in interest. Some stick to the old recipe, others enjoy the off roading and push the boundaries of themselves and/or equipment. Either by going nuts across the Simpson desert on a posty (CT110) for charity every year to test their endurance, or deck out the best of the best equipment to enjoy the riding and performance. This thread falls under the latter interest.

I've got to say that the improvement in equipment is massively noticeable. Both for enjoyment but mainly safety. Good gear saved my life in plenty occasions. I'm still suffering a fractures humerus (since November) after a front wheel wash out, at low speed (20-40km) not pushing it, on an old TTR. I ripped the rear hose out of the rear brake banjo with a bunch of vines stuck in the rear wheel on my WRR the day before. I was shitting my pants that whole day on that TTR. Felt more safe on the WRR without having a rear break on a trail ride half a day. And I'm convinced I wouldn't have crashed on it.

From this I'm further convinced that good gear is a prerequisite for going out, particularly remote bush, if you do decide to go there. Friends who have done those posty rides reckon they've never felt on the edge as much. And that's compare to race events. Just for a bit of background information, I didn't get choppered out. Instead having to sit in a bouncy car with either end of the bone playing chop sticks with each other. Luckily we trailered into the bush this time, so there at least there was a car. Glad I don't ride alone.
