Question asked from: http://www.carandbike.com/

The R15 gets a perimeter frame and with an engine which offers decent performance, there is little to find fault with its handling as a sport bike. The perimeter frame makes it one of the best handling bikes in its segment. You could also look at the Suzuki Gixxer SF is budget is a constraint.
