Thanks for all the replies guys.
Yeah a CBR250RR seems to be the way im leaning, highly recommended.......though most say to go for the Oz delivered version not imported. I'll do some more research on www.cbr250.com
Haven't heard of the other bikes but i'll do some research (google is my friend).
BNR32t...I think the CB250 was what i had to do the stay upright course on, not wrong about it being slow. I may be interested, did you want to PM me details?
Thanks to all.
