Came in quick. Easy install, though time consuming because of the lead behind the inner rear fender. Nice chrome finish.

Could not ask for a better deal and the part is working like a charm! Saved a lot compared to the Harley version of the same part. Looking forward to purchasing more accessories for the bike!
