this is way too big, but it is the bike i’d like to work up to someday:
honestly, get something old, small and slow. a friend of mine just picked up an old honda ascot that is in really nice shape for under a g. he loves it and is learning a ton from it.
BTW, if u get a honda, my sister’s BF works on hondas for a living and fixes them on the side at a very reasonable rate.
