I recently Upgraded from a 2007 c50-T with a 1400 rear end to a 2013 c90T BOSS. I liked my c50 but ride the freeway 30 miles each way to work. The more i Ride the C-90T the more i like it. I is a quite different experience from the C-50. I have ordered the GMAN bully fuel controller as the newer bikes are setup to run really lean so run hotter. The weigh is not an issue after a couple of days riding. I also goes like the wind but is not geared very well for city riding.
