Most bike shops carry the bolts: go to KawasakiPartsNation.com online, look up the Honda parts fische for your bike, find the bolt in the exploded views and write down the length and size. Nowadays, even Ace Hardware is carryin quite a bit of metric stuff than can work OK (heck, just look at all the metric chrome on MCrider's beautiful build: it's all Ace Wardware stuff!).
