Any sports bike 600cc and up will kill virtually any car on the road. And for the rare car where the owner has more money than sense sunk into his pride and joy, well a bike can just lose him in the traffic by lane splitting. I have yet to see a car that can beat my bike. I'm not saying that they don't exist, it's just that they are so rare that I've never seen one in over 3 years of riding. And even if I do eventually see one, he's still going to be stuck behind other cars as I lane split on up the road
Oh, note I said "sports bike" above. Harleys are usually 1000-1500cc, and yet they are absolute slugs. You could beat one in a V8 Commodore in both 0-100 and in top speed. So even if you have a mild GTS-t, give a Harley a go and you will probably win. They are also too fat to lane split through traffic
