Many many bikes have trouble with their battery terminals and the reason most people don't look at them is if it were in a car it would not start with bad terminals but on a bike it will fire up fine but give trouble later in the ride.
I'm with V-Tom, they are easy to check and a good place to start when fault finding, but really they should be checked long before a problem shows up, DO IT NOW why not.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
