I've got Napoleon bar-ends on my Street, which I love the look of (mean as hell) & give me excellent rear vision. But I didn't like the look of them when I put them on the Scram. I tried a round, CRG type bar-end, & they looked great, but the rear vision was crap. & I DO like to see what's behind me.
So I've gone with the Street's old lollipops. They look a little Mickey Mouse, though not as bad as the originals. & it's nothing I can't happily live with (hell, I had a big ugly Shu-Roo on my bike for 6 months, these are nothing) & the rear vision is panoramic (as it should be)
