Sec. 571.123 Standard No. 123; Motorcycle controls and displays.

S1. Scope. This standard specifies requirements for the location,
operation, identification, and illumination of motorcycle controls and
displays, and requirements for motorcycle stands and footrests.
S2. Purpose. The purpose of this standard is to minimize accidents
caused by operator error in responding to the motoring environment, by
standardizing certain motorcycle controls and displays.
S3. Application. This standard applies to motorcycles equipped with
handlebars, except for motorcycles that are designed, and sold
exclusively for use by law enforcement agencies.
S4. Definitions. Clockwise and counterclockwise mean opposing
directions of rotation around the following axes, as applicable.
(a) The operational axis of the ignition control, viewed from in
front of the ignition lock opening;
(b) The axis of the right handlebar on which the twist-grip throttle
is located, viewed from the end of that handlebar;
(c) The axis perpendicular to the center of the speedometer, viewed
from the operator's normal eye position.
S5. Requirements.
S5.1. Each motorcycle shall be equipped with a supplemental engine
stop control, located and operable as specified in Table 1.
S5.2 Each motorcycle to which this standard applies shall meet the
following requirements:
S5.2.1 Control location and operation. If any item of equipment
listed in Table 1, Column 1, is provided, the control for such item
shall be located as specified in Column 2, and operable as specified in
Column 3. Each control located on a right handlebar shall be operable by
the operator's right hand throughout its full range without removal of
the operator's right hand from the throttle. Each control located on a
left handlebar shall be operable by the operator's left hand throughout
its

[[Page 405]]

full range without removal of the operator's left hand from the
handgrip. If a motorcycle with an automatic clutch is equipped with a
supplemental rear brake control, the control shall be located on the
left handlebar. If a motorcycle is equipped with self-proportioning or
antilock braking devices utilizing a single control for front and rear
brakes, the control shall be located and operable in the same manner as
a rear brake control.
S5.2.2 Display illumination and operation. If an item of equipment
listed in Table 2, Column 1, is provided, the display for such item
shall be visible to a seated operator under daylight conditions, shall
illuminate as specified in Column 2, and shall operate as specified in
Column 3.
S5.2.3 Control and display identification. If an item of equipment
in Table 3, Column 1, is provided, the item and its operational function
shall be identified by:
(a) A symbol substantially in the form shown in Column 3; or
(b) Wording shown in both Column 2 and Column 4; or
(c) A symbol substantially in the form shown in Column 3 and wording
shown in both Column 2 and Column 4.
(d) The abbreviations ``M.P.H.'', ``km/h'', ``r/min'', ``Hi'',
``Lo'', ``L'', ``R'', and ``Res'' appearing in Column 2 and Column 4 may
be spelled in full. Symbols and words may be provided for equipment
items where none are shown in Column 2, Column 3, and Column 4. Any
identification provided shall be placed on or adjacent to the control or
display position, and shall appear upright to the operator.
