We have just received word that the ACU Motocross Committee has decided – after lengthy deliberation – that the current youth age groups and capacity allowance will be amended for 2017.

The ACU said the agreed proposal will bring the Youth class more in line with FIM Europe. The Motocross Committee feel that this is a practical rule change and does not create any safety issues.

The Youth Motocross Classes will include a new class 125cc two-stroke class:


13 years – 17 years — Youth 125cc — Minimum 120cc two-stroke maximum 125cc two-stroke Manual clutch, 19 inch rear, 21 inch front wheel.

In reality, it is allowing a rider of 13 years of age the opportunity to race a 125cc machine with riders up to the maximum age of 17 years.

This is an option for a 13-year-old and not compulsory as they can remain on a Big Wheel 85cc for a further 2 years if desired.

“I feel this is a positive move and the MX Committee have considered this from all aspects, said ACU Chairman, Brian Higgins. “It is quite a large step from an 85cc to a 250F machine and this optional class will allow for a year on the bigger frame machine which obviously handles differently.”
