Keep the Zuma. I just bought a new 2012 model, and got rid of a crotch rocket at the same time. I am 53 with some medical issues, and am giving up on large tall motorcycles. I have had a number of 650 dual sports, now I can't even get on one. My current dual sport is a Yamaha XT225. I have a 1500 Goldwing, which I am looking to replace with a large scooter. I still have my Vulcan 750 cruiser, and will keep it forever. It's heavy for a 750, but with a very low seat, and a low COG. I can flat foot it easily. I have crossed the country on it many times.
I now have a Zuma 125, a Vino 125, and a Stella 150cc 2 stroke. I intend to wear the 2 Yamahas out, the Stella can be rebuilt forever.
