Or buy the 3M film that is almost 3/32" thick. I did that on the ST1100 after I found a used headlight. I did my FZ1 and the better half's PC800. I may look at that option as you do not have to remove it to clean behind it. But, I know of at least one person who burned a spot in theirs after running the high beams for an extended time. Moby feel free to correct me if I got that wrong.
I think that's probably okay if you are just touring.. but if you plan on doing any off road stuff I feel - just my opinion for what that's worth - that going through woods and hitting branches or riding behind someone that might throw up a rock it's better to have a thick Plexiglas along with some space between the headlight to absorb more of an impact..
Even for touring, I've seen enough bolts in the road that I don't think the film will help with...
Of course, I've put 50k miles on my ST1300 in the past 3 years and have only very small dings in the headlight you can barely tell so maybe it's just a crap shoot to begin with.
If I figure out how to make something with plexiglas I'll post what I did with some how-to's.. Gotta have the bike first of course.. LOL
