Carrying a basic motorcycle toolkit can help you avoid small problems turning into big ones. This is the suggested list of essential tools that you should carry at all times on your bike.
Providing your motorcycle is relatively new and more importantly well maintained, and if it’s not an old clunker that’s on it’s last leg, these tools will take care of most situations.
However, the biggest issue you’re going to face is finding the space on a bike to carrying a few essentials you may need. Most modern bikes have a very limited toolkit – normally found under the seat. Chances are that kit is not going to be complete or that useful if you ever find yourself stranded at the roadside.
