You didn't mention what year your Street Triple is. The older Street Triples can take advantage of Tune ECU and get more than Dealer Tool provides. The 2013 and later Street Triples don't like Tune ECU, but they will work with Tune ECU Lite. There are other apps that will do what Dealer Tool does and they cost less.
With all that, I have Dealer Tool. I have had it for several years. It is user friendly so I use it. With Dealer Tool you can do diagnostics. You can use it -- along with hand tools -- to synchronize your throttle bodies. You can clear your little wrench after service. You can check for/ and clear fault codes. And you can use it to bleed ABS brakes during a brake fluid change. It is useful.
Dealer Tool does not let you into the ECU so you can't calibrate your speedometer, turn off injector cutout, turn off SAI, or change your fuel or ignition maps.
When you buy Dealer Tool, it is set up for one bike, but you can buy pass codes for more motorcycles.
