Most RE customers will be riding on more off road than on road.It's lardy because RE haven't spent any money to lighten it. Can't see it bothering most of their customers who won't use it for much resembling off roading where it matters. They'd rather save some money.
Both Himalayans are built for 2nd/3rd world riders. They are do it all vehicles designed to carry kids to school, dad to work and the family to the weekend market (yes all 4 of them). They will also be handed down a generation or 2.
They need to be rugged and robust because the vast majority of owners will not be riding in the Picos but the Himalayas and Andes.
The fact that 1st world riders bought the 411 in such numbers was a bit of a surprise to RE and they have reacted incredibly efficiently but to loose sight of their main market would be a mistake.
