I've been commuting on my SV for the last 3 years and finally started to make some modifications to improve the ride.
First on the agenda.
Givi A760 windscreen.
Pros - takes the wind off your chest on the interstate. I don't feel like I'm doing a constant pull up anymore.
Cons - a little bit of wind buffeting and extra noise. I wear ear plugs anyway so it's a non-issue for me.
The goods out weigh the bads.
My next mod is on order and I am anxiously waiting for its arrival! I have a SW Mototech detachable rack with a set of Givi E21 hard bags in route. The rack is coming in from Germany so I have to wait about 2 months

Hopefully these will add the MUCH needed storage for my daily commute. I've been using a set of Givi soft bags for the last 2 years. While they are good bags, I am ready for something more! I'll post up a few pics when they get in and are installed.
