The ERX narrow bubble is a full coverage fairing optimally designed for long wheelbase bikes. The fairing works with beautifully crafted hardware (sold separately) that allows custom adjustment of the fairing to suit your preferences. The hardware includes rubber isolating mounts, which help cut down on reflected noise and protect the fairing mounting holes from long term cracking. If you are thinking of eventually adding a Body Sok to your bike, you would use the larger WERX fairing, which is 2 inches wider than the 19 inch ERX fairing. To determine if this is the right fairing for your bike please see the fit chart.
