if these kids ( can't really call them adults based on your description ) are razzing your for wearing leathers and a helmet on a motorcycle ride I don't see that any of the bicyclist based suggestions from the denizens of the forum are going to be really on point. I don't wear spandex myself and my version of high viz wear is a yellow road workers vest from Home Depot ( $15 for a much better vest than my LBS had at $25 ). If you really feel like you need to count some coup on these bozos you might do some math on what it cost the average F150 super cab diesel to drive to work this week and then make a point of letting them know what it cost you to drive/ride to work this MONTH. Personally I think the real daring do's are the ones with a millimeter of fabric between their skin and the asphalt rather than three feet of steel to cushion their delicate, wimpy hides but thats just me.
