Physical Size Standards for ORMs

ORM operators must be at least 7 years of age. They should follow these suggested guidelines for a good rider fit.

• Leg Length: While seated, the thighs should be roughly parallel to the ground, and the knees should be bent at a 45-degree angle.
• Foot Length: When stopped, a rider should be able to reach the ground with one foot while keeping the ORM upright.
• Arm Length: When seated on the machine, a rider’s arms should be long enough to:
  • Turn the handlebars, and maintain a firm grip.
  • Operate the throttle comfortably when the handle is extended fully in a turn.
  • Operate the brake and clutch levers. The first joint of the middle finger should extend beyond the brake and clutch levers when the rider grips the handlebar.
