I am a fair-weather rider. No issues for me whatsoever. Even if I rode in harsher conditions with more exposure to sun, moisture, wind, and dust, I suspect I would report the same. The angle of the instrument panel, materials, and design provide a nice offset to normal wear. I had the same concern you have but took a different approach. I ceramic coated the glass to help prevent minor scratches and swirl marks. I also do not have anything attached to the key itself to prevent an accidental scratch while inserting the key and actuating the ignition. Although my motorcycle has low miles, I have seen fantastic pictures of speedometer milestones from other Forum Members. I have yet to see a noticeable scratch even on motorcycles with 100,000+ miles. David
