What windscreen models are available?
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.
This is an installed Double Bubble:
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:
A Laminar Lip is a bit of plastic that directs the wind higher than your stock windscreen does. Here is Laminar's explanation of how it works. They do make a couple models for the OEM windscreen. If you have one of the taller non-stock windscreens you'll have to get one of the universal Lip models and make it fit.

Opinion: In a word, WOW. Got the 14" cruiser style for my DIY screen. Very pricey at $95 for what is basically just a little chunk of plexiglass. OTOH, the design is brilliant and the difference in wind noise is amazing. In my particular setup, it makes a way bigger difference than earplugs. I put the 14" Cruiser on an 18" wide x 24" tall tombstone-style windscreen I made. The 14" Cruiser is a general size / shape. Though it does have a little more curve than my windshield (the top of my screen is a little flatter) it still works nicely. The 14" looks like it might work with the Duke / Mike style screen as well.
Second opinion: It's easy to attach; just clean your windshield with the supplied wipes, line the thing up (the manufacturer says to place the top of the stock windscreen one-half way up the Laminar Lip) and stick it on. The extra strength Velcro dots are attached to each other, and you just pull off the film to expose the adhesive side of the ones that go on the stock screen. The lip comes with an extra set of dots for you to have an extra mounting position if you need it.
The attached shield stays put at 60-70 mph (one BMW rider says it's fine at 125). It does seem to vibrate a little at higher speeds. I am 5' 10", and I noticed right away that the wind blast was directed to a different place. Instead of hitting me in the chest, the wind is directed up to around the top of my helmet. Before, with the wind hitting me in the chest, a ton of the blast was then directed up under the chin guard of my helmet. I do notice a softer buffeting at speed, and maybe a bit more noise. This is definitely an improvement at speeds over 40. Overall, I'm glad I installed the Laminar Lip.
This is mounted higher than what Laminar recommends. The owner has since moved the Lip down about an inch. He now finds that the air is a bit smoother at helmet height. "It allows me to sit in a neutral position with slipstream pressure mostly on my shoulders. Much improved over the stock screen. I think that for longer distances a taller screen would be the way to go, however. I think one of Mike's screens is in my future."
