Without a side by side comparison yet, I 've noted three different things already,...
The handlebar over seat heigth I haven't been able to find anymore. and
Two more new differences I've noted...
TRC 547.323.d states "A stoplamp shall emit a red or amber light, or a color between red and amber, that
is:
(1) visible in normal sunlight at a distance of at least 300 feet from the rear of the
vehicle; and
(2) displayed when the vehicle service brake is applied.
(f) A stoplamp may be included as a part of another rear lamp
TRC 547.324 d states "(d) A turn signal lamp shall emit:
(1) a white or amber light, or a color between white and amber, if the lamp is mounted
on the front of the vehicle; or
(2) a red or amber light, or a color between red and amber, if the lamp is mounted on the rear of the vehicle.
Note the glowing entries above....
These color additions mean that you can now legaly use your rear amber turn signal as a brakelight in addition to the turn signal function, And allows the use of white turn signals, which should make you more visible, and a amber brake light can now be used, which MAY be brighter than the red, but I think I'll wire my turnsignals to come on (I'll switch the 1156 assy. to 1157 assy.,with two functions, turn and brake) in addition to the brake light in the T/S housing. Just switch some front t/s housings out to the rear.
The first three main changes I've noted.
