250 two-strokes in MX1 AND MX2!

Two-strokes 250s will be allowed to race in either MX1 or MX2 classes next year as part of a shake-up by the ACU. The only exception is the Maxxis British championship, where current rules which allow 250 two-strokes into the MX1 championship will stand.

The changes come after consultation Between the ACU and multiple interested parties for many months, including several foreign Federations including Holland, Canada and Australia who have all trialled this change recently. Steve McCauley, Motocross Committee Chairma, said: “After much discussion and feedback from the numerous Federations as well as Teams and the Industry here in the UK, it was decided not to go ‘carte blanche’ with this change. As a Committee we will always factor in important feedback from our championship partners and never bring changes in on a knee-jerk reaction.

“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. By doing this we feel we are moving forward but in a controlled and correct manner. This option means we can offer flexibility and diversity whilst monitoring these changes in order to plan for 2019. We have also incorporated a ground-breaking first, by allowing the 250 two-stroke to remain in MX1 as well as now adding them to MX2, resulting in greater flexibility and choices for our licence holders.  Once again the ACU lead the way with innovative and measured changes.”

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.
