Unfortunately I have not seen any real world reviews. Seems reporters don't go out at night in all conditions, and it depends on their experince of what is 'good' in terms of headlights. An old Australian review of the ST11 said the lights were great..and perhaps they were ok benchmarked against what was around then. As I had decent lighting on my Suzuki at that time, I would given the ST11s light a fail mark.
