Sad news and I'm sure everyone here would say sorry hear about the families loss!
However, when will tourists coming to Asia ever learn? Riding a motor bike, no helment, no protection etc, etc, etc. Likely not a motor bike rider at home. Maybe tourists will never learn, they think being on holiday and in a different counry they are made of steel.
RIP young man, another life wasted that very possibly could have been avoided.
