I have a 2019 Ryker 600 ACE.
...saw an air deflector on Amazon ("Goldfire Universal Adjustable Wind Deflector") and have been trying it with the factory windscreen. It costs $22.99.
I always wear a full-face helmet and any wind blast/noise previous to trying the deflector has been a present but not huge issue.
On recent rides this cheap deflector pushed away enough wind so I wasn't bothering to lower the helmet face shield, and noise was reduced. I think the item is worth the price.
Still playing with tilt angles on the deflector and trying to get used to the look.
