I am looking at a GSX 550 for the wife for next winter. I'm looking to trade off the ZR so I can go back to riding my F5 and get the wife something different. She is not a hard rider. She needs something with electric start and smooth ride mainly. She likes the looks of them, the standard reverse and mirrors are nice features. They had a 2009 model at the show in Fargo this week that we checked out.
The local dealer has a 2007 GSX 550 with about 900 miles. How do they compare vs a new Twin Spar F5 for ride quality? How are they holding up for everyone? Any other advice??

Thanks
