I'm leaning towards getting a 250cc bike. Something along the lines of a Honda CBR250R or Kawasaki Ninja. I am not interested in carrying a pillion and would prefer the space to be made available for luggage. Also by turning it into a 1 seater would save around $300 a year on rego. At a guess (or professional estimation) what would the cost be to get the second seat removed and replaced with a basic metal rack?
