Well, let me list down the essentials.
A tube, extension cable, 2person tent, clutch and race cables, rope, 9x12ft tarpaal/nylon sheet, chargers and a soft cusion for the seat.
Other than that, my DSLR hardly came to use as the bag was mostly packed under the waterproofing during bike rides so mobile came in handy., Tripod, clothes, (warm inners, a jacket, warm cap, etc) other than summer clothes. Panadol,Brixen and Flagyl tablets.
What we did not take: Airpump, puncture kit. I personally think that is waste because in case of such incident, one can easily take help from any passing truck/Suzuki to take a drop till nearest petrol station. That sounds risky, but is actually very easy solution.
