That said, the headlight does shimmy more with use of the Marllin then without. I believe this is happening because the Marlin is attached to the headlight bracket assembly, which as SportsterDoc notes, is rubber mounted to reduce shock, and the Marlin catching wind is inducing the vibration.
What I can say is this -- before the Marlin I observed very little movement in the headlight when at speed, with the Marlin I observe a fair bit of headlight shimmy at speed. This is only noticeable when riding in the dark so it may not matter to you. For me, I find it distracting, but not enough to remove the Marlin.
Do the 2017 Dart brackets move the headlight bucket further forward than stock, as SportsterDoc mentioned about his 2014 Dart brackets, and if so by approximately how much? I went out in the garage last night after reading SportsterDocs post and did a light push on brackets of my stock 2017 set up. I saw the slight flex caused by the rubber mounts, just as SportsterDoc said. Reminds me of the rubber headlight mounting on my previous bike, a Harley CVO with Springer front forks. My riding buddies said they knew it was me coming toward them from a distance, because they could see my headlight ( in daylight ) bouncing around LOL. With that in mind, the headlight shimmy is not necessarily concerning to me, as I rarely ride at night. What would be of concern is what I can see in the daytime that might be distracting. So, my question is whether or not enough shimmy is transferred to the screen to make it distracting, or not.
