best practical 250 to get would be the VTR250 in NSW, doesnt look too bad, if you drop it no fairings to break, great on fuel and rego is sweet too, good resale value too like the cbr's. dont get an rvf400 because it looks horn, they are a nice bike, but rego'ing the thing is the same price as a 600cc not worth it in my opinion close to 1g, save yourself $500 and invest in some good gear.

also servicing the vfr/rvf 400's cost a bit, the plugs are quite rare and need some special tool to remove them, looking at about $15 a plug, and i dont think their iridium from memory.

i myself ride a NSR250, its light, has power and makes alot of noise so dick head drivers can hear you and not lane change in to you

also note, in NSW you can ride in bus lanes what ever the time and lane split whilst traffic is stationary.

safe riding!
