Page 242 Rule 4.2 BRAKES
For Youth Competitions, all machines must be fitted with an effective brake on each wheel, with the exception, machines used in the International 125cc and 250cc Four Stroke class competitions where brakes are not allowed. Machines without brakes cannot compete in the same races as machines with brakes.
THIS IS INCORRECT AND NO RULES HAVE BEEN CHANGED THE FOLLOWING IS CORRECT:
Youth machines only require one effective brake fitted on either the front or rear wheel.
For clarification 500cc Sidecar machines DO NOT require brakes.
Page 245 Rule 4.15 SPECIFICATION OF THREE WHEELERS CATEGORY 1
Streamlining – Streamlining is not permitted. Streamlining is defined as any addition to the handlebars or to the frame of the machine, the effect of which is to shield the rider’s arms, legs or body from the air stream.
THIS REFERENCE IS INCORRECT and should be included in section 4.20 Number Plates and refer to solo machines only.
