Folks Don here at F4 Customs. I thought it might be appropriate as a sponsor and manufacture to try and give an opinion on what our findings have been concerning vents and windshield selection.
We often get calls and asked "what is the best way to improve my ride and what windshield do I need"? This is surely based on your riding style, height, inseam, and those types of factors. Maybe this will help.
Width: In our findings the best way to improve your ride on the RT is by going wider and vented. Here is why: The stock windshield is 25" tall and the width does not take the air out and around your shoulders like most riders want. The F4 is 2.5" wider on each side giving you more wind protection and more comfort on those long rides.
Vent: The vent is used to reduce the back pressure, move in fresh air, and also get air to the rider when desired. The OEM shield had openings in the windshield about the second year they were making the RT for just this reason. Our philosophy was not to have cut outs but to add a GL1800 Vent so that the rider has control of the air flow in all riding conditions.
Height: We offer 3 different heights 22", 25", and 28". The 22" and 25" can be purchased in standard width or the wide version. We normally advise the wide for the reasons I suggest above but sometimes riders say I like what I have but I want tint or a vent so we offer the standard width as well.
Clear or Tint: This is a factor of your riding style. If you ride mostly during the day then tint is a nice option to cut down on some of the glare from the sun. If you ride a lot at night and look through the shield we recommend the clear just for clarity sake. The tint is a light tint and some folks prefer it to cut down on the on brightness of the on coming traffic but I prefer the Clear for night time riding.
Number 1 seller; The best seller is the SRT-PLS3-V-W. This is the shield that is 28" tall and is wide with a vent. This comes in clear and tint also. The reports we get state that folks that are riding with a co rider and want the best wind protection have found this to be the best option for them.
Material: F4 Customs produces all of their windshields from Highest Grade Polycarbonate and we bake in our proprietary coatings which gives you these results:
Absolutely clear with no distortion.
Extreme Scratch Resistance even when rubbed with steel wool
Rain Shedding is fantastic light Rain X on steroids
Chemically Sealed so just clean them with paper towels and any glass cleaner and ride.
I know this comment was long but I hope it helps in your decision of what is the best shield for you and your co rider.
Feel free to contact me if I can offer any more information.
