I recently needed to purchase a couple of hundred dollars worth of parts for the ST11, My previous parts supplier here in Melbourne has dropped his Honda dealership and switched to Yamaha.
I remembered seeing this thread. (Thanks Alan)
So I came up my my list of parts went online with Partszilla as well as Blue City Motor Cycles in Mount Gambier.
I found that Blue City were around 18% cheaper than Partszilla on a 24 item $US419.44 order. With the currency today making it AUD $541.59.
Blue City supplied it for $441.43 GST inclusive.
