...You also mentioned that your current setup doesn't interfere with the passenger comfort witch is somewhat important to me.
BTW I'm looking at those european Yamaha city bags and I'm thinking to call a n old friend of mine to see for how much will I be able to get them.
Yeah, when I was mocking it up, it was important to keep the pass. pegs usable, since the Givi's take them away. I put my wife on the back, and she said it was comfortable and her calves didn't hit the bags. I still like those 'city bags' as well, but the price I found was in the neighborhood of $700 US. Let me know what you find out.
