I am debating on which on to get! i like the 500r because it has pleanty of power,i love the price and the MPG. i like the 650r because its more power.
if i get one of these bikes, i might be taking up to a 2 hour ride to places( MAYBE) even less then that. i want a bike that is a nice ride and that wont kill me being slouched for that long. also the bike that has less vibration is the one i would love.
