ZG makes two models that fit the 250, their stock replacement model and the Double Bubble. Both come in a wide range of colors. Below is a comparison of the Double Bubble and OEM screens.

ZGDB Observations
To be honest, the reviews on the Double Bubble are mixed. If you are on the short side, or you often ride in a tucked, or semi-tucked position, this could be a good mod for you. It really isn’t a substitute for a taller touring shield, though. Let’s see what some owners have to say:
- The double bubble on the 250 makes a good bit of difference. Nothing like you're going to get with a Duke screen, but it's a nice change over stock. Instead of the wind hitting me in the chest, the DB moves it up to the helmet, where there is less resistance.
- I got the DB and it definitely makes for nicer tucking; you can stick your head down there and get out of the wind completely. You won't get too much of an improvement besides that. I'm 5'6".
- I have the ZG double bubble windscreen. Although not extremely effective, it is an improvement over OEM for sure! If I were to spend a lot of time on the highway, I would definitely look into a really tall windscreen.
- A double bubble deflects wind in a different pattern. It's noticeable, and it changes with speed. Overall, it feels that it pushes the wind just a bit higher than the stock windscreen, probably 2"-3".
- In my case (6'2") it's a moot point. The results were well below my expectations. I found that I gain a couple of inches of still air, which does not do me much good. For you, this may be exactly what you are looking for.
- I have a double bubble, and I noticed the wind flow moved from my shoulders (with stock) to my ears, which makes for a louder ride. I am 5' 9".
- At 5' 8" with a 33" inseam (a lot of my height is in my legs) from what I can tell I would be giving up a lot aerodynamically and gaining little protection-wise with a larger windscreen
- I have a double bubble and it has changed my life! No more feeling like my arms are going to get torn off at 75MPH. I can actually cruise about 80 on the highway quite comfortably now, but I am 5'6".
- Being a short rider at 5'4", the ZGDB does a great job of moving the airflow from the bottom of my helmet to the top of my helmet while riding upright.
