Not sure which other continents you've ridden in, but assuming at least some of your trips were in developing countries with poor road and traffic conditions, and so you know what type of riding you are likely to encounter and what kind of bike you want to do that on. I haven't ridden the ktm but that's also probably what i think is one of the more interesting bikes available there. I agree the Himalayan is heavy and slow, but on the good side the suspension geometry works quite well absorbing broken pavement, and potholes, and it does off-road work decently albeit not in an exciting way. Enfield also have released a couple of 650cc twin cylinder bikes that also look worthy of consideration. I think those should definitely be looked at as well. I haven't ridden the dominar (400cc Bajaj), but the 200NS, and 180 dtsi Pulsars are pretty decent bikes, in my opinion.Especially for the price. I did a great tour through the Himalayas on the 180 and was pretty content with it. That was before the Himalayan had been released so I was comparing it to the Enfield Bullits and Yezdis which are problematic, heavy and slower than the Himalayan so it wasn't a tough choice. You can manage to ride through snow, an dirt and mud. Not in an enduro style but you can get across safely and reasonably quickly. They are light and well balanced, good disk brakes, and FI. But they are more road biased and possibly still not powerful enough for you. I found build quality to be quite decent and aftermarket and OEM spares are available. Just remembering now you said you are 6'5 so they may be way to small for you. I managed at 6'1 but you would have to check out the marketplace to see what is available and what will suit you best. If you want a western style level of power and performance it's probably going to cost you excessively in terms of time and money, spare parts and repairs can also get complicated. I think in Kathmandu there was someone renting or selling older Japanese dual sports and I am pretty sure in both India and Nepal I have seen the odd tour operator renting out bigger BMW's and stuff like that, but that's likely going to be cost prohibitive. I think the BMW 310GS is probably also worth looking at, but most likely the KTM 390 will suit you more. In Delhi and most major cities there are rental agencies where you could go and probably get a chance to try a few of these different bikes to get some idea of what they are like and if you would be happy with them. Outside of the himalayas (which is also probably one of the best areas to ride) most of the roads I have been on are pretty congested and in poor condition, with a lot of dust, noise, and pollution not to mention wandering animals, broken down vehicles and buses and lorries overtaking aggressively and with very little forethought. There is lots of exploring to do and you can get to some pretty interesting places. Just not likely to manage to do that tearing it up on an Enduro. I am pretty sure there are a couple of more street orientated bikes in the 250-400cc range as well. I dont remember the models but pretty have seen some Indian production models that are sort of cheap imitation super bikes as well as possibly some of the Yamaha, Suzuki, Honda dealers being able to order the more expensive models at a much higher cost than you would pay in Europe or North America
