Welcome to the forum and congrats on your new Bobber. Regarding GT85, everything Iíve read about it is from bicycling, not moto mags and even they admit that while itís a good all around product for many things, suggest that there are specific products that are far better for individual uses. So, for example, there are better chain lunes, overall cleaners, etc. One thing they all say is not to get that stuff anywhere near your brake pads. I would decide what it is you want to clean and protect and then look for reviews of products designed for that. Iíd make some suggestions but, donít know the Aussie market well enough. Iíll bet your moto store will, though.
