Hi and welcome vx!
I bought mine a year ago, and quickly became bored with the torque curve; fast, but utterly predictable (like a big electric engine). Putting on a full exhaust system (which gets rid of the cat) made the bike a lot more enjoyable/aggressive, partnered with extensive dynotuning. Sounds nuts, too.
I put on an aftermarket quickshifter and launch control/race unit which increases the fun again, but I'd recommend talking to Todd Spiers on this site; he's one of the best flashers for this bike in the world, and is over in NZ. Don't get a power commander, as the ECU flash is much more effective and allows quickshifter functionality too.
I raced my bike last weekend around the track in Adelaide, and was keeping up with fully race-prepped bikes; Bkings are amazing when livened-up!
One side note: the bike's suspension is set hideously soft from the factory, set for about a 70 KG rider. Spend the $50 and get your local race bike shop to set the suspension for you (and levers etc at the same time, if you're not wrenchie).
but learn from the fast black bking riders (
