On the WRT website, they outline the things you need to flash a bike. One is the Bin Definition File. If WRT software doesn't come with your bike's bin definition (which are all Suzukis), you must buy the Bin Definition File to even have a chance of reading or writing the ECU. Let's take x ECU for example.
The Bin Definition File for x1 is permanent. The purchase of the Bin Definition for x1 includes 1 Bin Definition Flash Key. You flash x1, this consumes the BDFK included. If you want flash x2, you must buy another BDFK for x ECUs. Now, after flashing x1 or x2, subsequent flashes do not require a new BDFK. However, you end up with x3 (doesn't matter how) when you go to flash it the software's going to tell you that you have no keys left.
NOTE: I cannot be held accountable for descrepencies on WRT's website.... as far as 1 or 3 keys.
Per the WRT Support Website:
Each Bin File Definition purchased entitles you to three keys to flash three separate bikes/ECU's. If you want to tune more than three bikes, you'll need to buy another key/s.If you're a tuning shop or dealer, and you purchase an annual bin file definition subscription to a particular make of bike, you may flash as many bikes as you like for the period of the subscription.
Note: The Keys do not apply to the free bin file definitions, you can flash these ECU's as many times as you like.

This product comes with 1 Bin File Definition Key allowing you to tune 1 ECU's as many times as you like. Additional Bin File Definition Keys are required for each additional ECU's and can be purchased from within the WRT software.
So maybe I have the price wrong, maybe it's not $100 per key, but it does have to be purchased.

Yeah this I don't know, I'm asking more than I'm telling. I'm not sure if every change requires a flash/reflash or not.
