Some folks are a little confused on both the schoolboy classes so read more for details.

Sorry for the confussion.

The 122-150cc class is for riders 12-16 years of age, they can ride the following.

86cc-125cc two stroke
75cc-150cc four stroke
Minimum Wheel sizes- 19" front, 16" rear


The 122-250cc class is for riders 14-16 years of age, they can ride the following.

125 two stroke
144 two stroke
250 two stroke
250 four stroke
Minimum wheelbase 53", no mini or Supermini

NO "A" Class Riders are permitted to run Schoolboy classes.

For more see the  AMA RULEBOOK

A Lot of folks last year thought these classes were 2 and 4 stroke specific as in years past but that's not the case.

I hope this cleared things up for everyone.

See yeah at the track.
