I found them great with no need to replace. the mirror shape is teardrop, I’ve seen them inverted (new storm) where the bulge of the teardrop is pointing to the outside. This will give you more handlebar clearance but also a better viewing picture with the bulge on the outside. Easier to lanesplit now, maybe 3 inch gain. Mine was with the bulge to the inside on delivery. will post pic later…
when looking in your mirrors or instrument cluster (Car or bike) you will briefly take your eye off the road, this is normal at least for me. what you do want is the largest/clearest picture, hence the bulge to the outside. hope this helps…
