I've had one every bike I have had an they have been excellent but on thee GS I have a few problems with it:-
1. The harness does dot enclose the front of the tank completely and road crap gets inside it so it has to be removed to clean under it regularly something I did not need to do on the other bikes.
2. Try as I did I could not get the filler and badge openings to all line up at the same time.
3. The badge clear panels are almost constantly misted with condensation, you can cut them out but more road dirt gets in.
Having said thet it is an excellent way to mount a tank bag or map holder.
