My 2009 Touring bike does pick up a little bit of a vibration when I sit at a stop light and hold down on the front brake. If I relax the front brake the vibs stop. It is insignificant and not a problem for me. I believe that by engaging the front brake at idle you are just transfering a little of the shake that goes on when a Harley idles. Just for the heck of it, when you are idling at a stop sign and notice the vibration when you engage the front brake, pick up the rpms a little and I will bet the vibration goes away. That is just the way the beast is. I call it character. If you own a Harley, new or old...it has character. The only way to rid your Harley of it's distinctive character would be to trade it in for a, shall I say it...a Honda Goldwing. Goldwings are Harleys that have been neutered. You know, steers. Still,, they are nice, just no character.
