It can. I have picked out a supercap module to add to each of our bikes to help the battery. It would be added in parallel with the battery to aid restarts when the engine is hot. A hot start really loads the battery hard and these batteries are pretty small. Most are 10AH so are 1/10th of a car battery. When hot the metal expands and tolerances are very tight. Many people get a 'clunk' when trying to do a 'hot start'. A supercap by itself would not be a good idea and would cause many electrical problems in the future.
