Im twenty from the blue mountains near sydney... i would not know what to suggest but u will want a couple of grand on mods too get yourself started in racing... ive had the cbr250rb for 2 months now i find the throttle to be nice and crisp but is lacking in the top end, to minorly erect it you will want to change your your final gearing, get yourself a programmable ECU remap it and maybe chip it, and of course u will know to change that ugly and dissapointing stock exhaust... that is all i can suggest
