I have been talking with a few of the seat manufacturers about making seats for the sx and rx, Corbin seems like the best opportunity. They need a bike to to use in order to design and shape a seat, they told me the person who lets them use a bike will get a free seat. So we need a volunteer who lives near Hollister California. As we all know the bikes are great but a better seat would be a welcomed addition. Contact Corbin Seats to set up appointment, 800-538-7035.
