We still have this daft thing with >600cc paying more but we're down to sub-Arab-prince levels once again: $426 instead of $745, up from $252 so still nearly double. 50cc scooters, probably the most environmentally friendly form of transport that doesn't involve some fat bloke shoving his arse against yours, are still getting it in the face with the rate going from $59 to $129. Yeah, more than double.

The >600cc thing is daft. There are, out there, plenty of 650 singles (adventure bikes, generally) generating perhaps 40hp max. There are also loads of 620 v-twins in Ducati Monsters (60hp) and the 650 parallel twin used in the ER-6 and Versys (70hp) will also attract the higher tax rate. In the cheaper bracket you can still get a Yamaha R6 - 120hp odd and a machine designed entirely to go very very fast. So as a way of discriminating it doesn't work very well and is clearly the work of some daft pencil pusher. FWIW I'm 675 and probably about 95hp.

Hate it. But I can live with it. Still won't be voting for National.
