Aprilia Accessories Tall Windscreen (w/DOT Stamp) - 2S001622
This screen is essentially identical to 2S001576 (sold elsewhere on this site) except that this screen carries the DOT regulatory stamp for riders in states where that is required.
An official accessory windscreen that will prove to be a godsend for reduced buffeting for long distance riders or to give larger track riders who are not GP jockey sized something to tuck in behind on the straights.
