I have a K1 and K1S and I bought the black color visor since I wanted to test it out first. To be honest the visor is not bad at all. It's darker than the original black AGV visors. It's definitely more flexible compared to the original and I'm not sure why but on my K1S it has a bit of a gap when I push it down but it fits perfectly on my K1. On the photo I'm with the K1S helmet. I will be purchasing again ^^
