Part # 43956301-302
Wunderlich Marathon Screen
Available in: Clear or Tinted

The stock windscreen is bad. I took mine off and rode it in a semi naked style. After much research outside of the United States, I went with this one. While I was very worried about dropping near $300 on a $10 worth of Lexan. It is well worth it. Trust me Wunderlich did there job in the aerodynamics department. Like everyone says it is so much smoother and makes the ride enjoyable. Also drop the wind noise down to a much more appreciated level. I ride with it in the upper holes and lower position. Gives me good amount of tucked protection or nice breeze if I sit up not the Class 5 hurricane the factory one created. I am 6 Foot and 36 waistline. The windscreen has not negatively affected my MPG or top speed if anyone worried about Aero Drag.

I rode with this in both the lower mounting holes and upper ones. In the lower ones it's simply better than stock. Similar airflow but totally smoother. In the upper holes the low position gives you airflow across your lower chin area but is still decently smooth. In the upper position there is vitally no pressure on you at all BUT, interestingly enough, there is increased airflow at your sleeves compared to either position in the lower holes. Great when it's hot but could be a problem when cold. I'm thinking I'll be keeping it in the upper mounting holes but may consider switching to lower holes if really hot. The windshield does vibrate a bit compared to stock but the airflow is again way nicer so I can put up with it. For size reference I'm 5'11" with a 30" inseam riding on the standard seat.
