I put one on my GL1500 and got to say it was the best investment on that bike ever. Had it on for 6 to 7 years and 70K miles, washed the windshield every day I rode. With just very few minor scratches caused by me hitting something, that F4 never scratched or hazed. Wished I would have looked there first before I bought my Slipstream Bagger, it's already getting small scratches (only had it for 4 months ridding time) and i'm very cautious when cleaning windshields. I got spoiled on the F4 on my 1500. Should have bought that instead, will replace this with an F4.
