Hi
I have caught the long distance ride mania (Bike)

I have a TVS Victor GL bike which has clocked around 30,000 km
I have also done a few solo 100 km runs oneway
Now I plan to do longer runs
Can someone guide me , what all things do I need to check and carry with me from a bike's point of view during long runs.
and what things I am likely to face during such trips
Ps: Is it a good thing to fit my TVS Victor with thicker tyres ?
thanks
