I carry most of the tools that I might need, including a small socket set that includes some small spanners. I also carry a long series socket and wrench for the rear spindle nut as this is not included in the standard kit and as a minimum you would need to adjust the chain. Chain oil, WD40, gaffer tape, cable ties, spare connectors and a few terminal connectors, fuses bulbs, hand cleaner and disposible gloves. A Pucture repair cannister and spare specs!!!!!!!!!!!!!!!
