Section 4.06 - Procedures for Inspection of Motorcycles(1)Prior to Beginning Inspection. A visual check of the motorcycle shall be made to determine that under-inflated tires, condition of suspension and other conditions visible to the inspector will not impede or interfere with the proper aiming of headlamps. In order to proceed with inspection, a properly functioning side stand or center stand must be able to support the weight of the motorcycle while wheels, front end and swing arm are examined. Passenger foot rests should be put in an upright stored position, if possible, to prevent interference with the inspection.(2)Inspection of the Motorcycle. 540 CMR 4.06 shall apply to two wheeled motorcycles or two wheeled motorcycles with a side car. All inspections must be performed in accordance with the applicable provisions of 540 CMR 4.00 by certified inspectors in the approved inspection area only. Inspectors must first collect the proper fee and secure the proper Certificate of Registration or the on-line renewal confirmation receipt. The Certificate of Registration shall be inspected and the information contained thereon, including license plate, vehicle description, and vehicle identification number, shall be verified by observation of the subject motorcycle. The information contained on the Certificate of Registration shall also be matched with the vehicle information accessible to the workstation. The data appearing on the Certificate of Registration, the data accessible on the Workstation, the data appearing on the vehicle license plate, and the vehicle identification number and motorcycle description must match in order for the inspection to proceed. As per M.G.L. c. 90, § 11 online renewals do not require a valid plate decal. No fee shall be assessed for an inspection which does not proceed due to a data match failure. The following inspection shall then be completed: (a) The number plate must be undamaged, securely horizontally mounted on the rear of the motorcycle, clean and clearly visible. No accessory mounted on the motorcycle may interfere with a clear view of the number plate. Any decorative number plate or number plate replica not issued by the Registry of Motor Vehicles for the motorcycle being inspected on which appears any jurisdictional name must be removed from the motorcycle.(b) Upon the completion of the inspection and a determination by the inspector that the motorcycle meets all inspection requirements, the inspector shall affix a new Certificate of Inspection to the license plate and provide the operator with all inspection documentation and program literature as required.(c) A motorcycle which is determined by the Inspector not to meet all inspection requirements shall be issued a Certificate of Rejection document in accordance with any regulations, policies or procedures of the Registrar.(3)Brakes. (a) Brakes must be adequate to stop a motorcycle from a speed of 20 MPH in not more than 19 feet. Each motorcycle shall have either a split service brake system or two independently actuated service brake systems which, upon application, act on front and rear wheels. Any motorcycle which has a number plate issued under the provisions M.G.L. c. 90, § 6A (Plates for Antique Motor Cars) which was not manufactured with either a split service brake system or two independently actuated service brake systems shall be required to have one brake system adequate to stop said motorcycle within the aforementioned distances. For more recent model motorcycles observe whether the motorcycle utilizes a brake anti-lock equalizer system which proportionately controls braking pressure to the front and rear wheels.(b)Mechanical Brake System. Inspect the linkage, cables, pivots and bearings for high friction, wear and broken or missing parts. Reject motorcycle if: 1. Brake adjustment changes under any steering or loading.2.

Any brake adjustment mechanism which will not maintain an adjusted position or is adjusted to its maximum extent.7. Front brake cable is routed so as to be pinched between fork and frame.8. There is any roughness, binding, or jamming in levers or pedals.9. Less than 1/3 reserve remains in hand or foot brake when brakes are applied.10. Modifications make the pedal or lever inaccessible for adequate leverage or operation.11. Any portion of the brake hand lever is broken or missing.(c)Hydraulic Brake System. Visually inspect the condition of the hydraulic system. Note: Do Not Remove Wheels. Reject the motorcycle if: 1.

The push rod is improperly adjusted.5. Wheel cylinder or caliper leaks or fails to function.(d)Hydraulic System Tests. Test motorcycle in a standing position. The inspector should be able to maintain brake or hand lever reserve under moderate force (40-60 lbs.) for 15 seconds. Reject the motorcycle if brake reserve cannot be maintained for 15 seconds or if there is less than approximately a of the total available pedal or brake lever travel remains. The brake lever and pedal should exhibit smooth, firm and responsive action. Allow wheels to turn freely when not in the braking mode. Reject the motorcycle if binding occurs and wheels do not turn freely.
(e)Visual Inspection of Brake Pads and Discs. Where pads and discs are visible check and reject if:1. There is any substantial crack extending to the edge of the disc or pad.2.
