I spoke to them a few days ago. they moved to NC so their number has changed. I ordered a set from Amazon and amazon screwed up and sent me the stanard set vs the metric set. I called Cycra (maker of Hardstreet) and they informed me the only difference was the bolts. He said that he will send out the hardware to me no charge right away to make it right.
His name is Jay and his number is 888-481-7269 so If you have any questions give him a call. He did tell me that they make the Yamaha hardbags also, maybe that's why you guys recognize it?
I will post an update once I receive the hardware and get them installed.
