Wow the tide is starting to turn slowly. Just need them to include pro racing now. Come on ACU you know it makes sense !

For the 2018 season the machine capacities for MX1 and MX2 will be as follows; MX2 120cc to 250cc two stroke or 175cc to 250cc four stroke.

MX1 Over 175cc to 500cc two stroke or 251cc to 450cc four stroke. Electric machines with a maximum output of 16kw are only allowed in the MX2 class.

16KW for electric is not a lot. The alta puts out 40 HP - which must be in the 30's for KW.

500 two strokes ok ?

I have no idea on the electric side but I did raise an eyebrow at the 500cc limit for MX1, is this a first or can you race one in OZ/Canada?

Be interesting too see how many opt for a 300.

Awesome to see this, as far as I know there is no sort of production rule in the British Champs so might see a 500AF or two.
Good that electric bikes are being included as well, even if some tweaking is required.

Check the one proviso :

" “Therefore, we decided to introduce the changes detailed below into the MX standing regulations, which allow organisers to take advantage at all levels with the exception of the Maxxis British Championship."

The Maxxis British Championship is the British National series, to my knowledge. So, it's still the same as say, the US Nationals . So, there's No equivalency in the Pro National Championships.

Norway also went through with this rule change a couple weeks ago. :-) Exciting times for next season!
