Riding in Myanmar is dangerous, only 10-15 motorcycle tour groups have ever ridden in there so far (Som might be the first Thai lady to ever ride a big bike in Myanmar, Cheri for Singapore might have been the first female). They are not used to your speed or size, the most dangerous time is around 4-5pm, students on bicycles, people off to buy food and generally running around, it is one of the most dangerous countries ive ever ridden in.
Big, metal pannier boxes are a liability. They are wider than you and will catch on anything that is too close, with their sharp corners they are like fish hooks, you have far more chance of a deflection without them which might save you from crashing. Over the Dawna Mountain Range, judging gaps is much harder and splitting traffic often impossible. For most of the developing countries, I think they are a hindrance and so did the riders with them. The argument that they will protect you when you lay the bike down, I dont think holds merit. The Giant Loop "n" shaped bikes arrangement works excellently here.
Laws are that the bigger vehicle has to look out for the smaller vehicle in ALL circumstances, ALL. A bicycle doing a last second U-turn in front of you without looking, you kill him, it's your fault. RIDE SLOW through villages and towns, 40km/h especially 4-5pm, it will save you having the reaction time to deal with events.
