I bought the gs911 mainly for 2 reasons:
1. I do as much of my own servicing as possible, and this tool ( yes, it is just a tool)
gives me the opportunity to do just that.
2. How good, no, make that great is it to be out in the middle of nowhere, and be able to diagnose and fix a problem on the side of the road, and continue on with your trip, as opposed to calling for the nearest tow truck ( if your phone works )and having your bike taken to the nearest dealer, who is more than likely a million miles away, therefore ruining your trip.
These things are worth their weight in gold if you ask me, and it lives in my toolkit with all of the other essentials you need when out on the road.
For the sake of a few hundred bucks, it sure does give you peace of mind.
