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 bay only. Inspectors must first collect the proper fee and secure the proper Certificate of Registration, except for motorcycles submitted for inspection displaying temporary plates, dealer plates (as defined in 540 CMR 4.02) or motorcycles that are in the process of the seven day transfer of registration (under the provisions of M.G.L. c. 90, § 2). The following inspection shall then be completed:

(a) The number plate must be undamaged, securely 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 the word "Massachusetts" must be removed from the motorcycle.
 

(b) A Certificate of Rejection shall be issued, after inspection is completed, for any of the following:

1. expired registration,

2. registration number and number plate do not match,

3. description of motorcycle does not fit the motorcycle,

4. vehicle identification numbers on the motorcycle have been removed, altered, or are illegible, or if any of the characters on the vehicle identification plate do not correspond with the Registration Certificate.

(c) A Vehicle Identification Number Correction Form must be given to the operator of any motorcycle rejected due to the identification or registration number.

(3) Brakes.

(a) Brakes must be adequate to stop a motorcycle from a speed of 20 m.p.h. 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. Cotter pins are missing.

3. Pins or clevises are worn more than 25% of the original diameter.

4. The cam operating lever has been repositioned on the shaft as a means of avoiding replacement of worn cam, shoes or lining.

5. Any cables are frayed (two or more broken strands).

6. 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. Hoses or tubing leaks or they are cracked, chafed, flattened, restricted or are improperly fastened.

2. Master cylinder leaks or the reservoir capacity is less than the manufacturer's recommended safe level if known or less than 1/2 total capacity.

3. There is any leakage in the brake system.
4. 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 1/3 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. There is evidence of mechanical damage other than wear.
