No.....just the back. My g/f keeps sliding fwd, so I figured to try one hole in the back to start. If it doesn't work or ride right, I'll get her a custom rear seat.
If she is sliding forward, then she is riding wrong. When coming to stops, she should put her hands on the gas tank...
A tobin seat is only going to help keep her planted on accels, not decels.
Just put velcro on her ass and be done with it.
