All of the front parts of the two frames look identical
side by side, dirtier frame is the B2.
The only difference is in the rear part of the frame where the seat, taillights
and rear cowl (tailpiece) all mount up. B2 is in the front in this picture
and you can see that it doesn't have the stubs where the taillights on an A2
mount as the frame in the rear does and the brackets where the seat and
tailpiece mount on an A2 are in different positions. On a B2, the seat is
in two pieces and it has no rear tailpiece. The saddlebag brackets mount
to the rear of the frame instead.
A2 in front. An A1-A5 frame should all be the same, A1 = 1979, A2 = 1980,
A3 = 1981, A4 = 1982, A5 = 1983, and I assume that the Z1300 frames are the same
as ours all the way up to 1983. However, starting in 84', the ZG1300
frames are most likely different from all other 1300 models even though they
basically look like a Z or KZ because these bikes had fuel injection. I
suppose they must have a different arrangement of mounting tabs welded on to
support the components that go along with that setup.
Here's a list of items mentioned by Gary G. that are different between the bikes:
Rear section of frame is different as shown
above, (no mounts for tailpiece or rear turn signals)
Gas tank is larger (uses the European spec tank, but all 1300 tanks are
physically interchangeable)
Stock B2 handlebars are longer, pull farther back ( unique to the B2)
Front brake master cylinder is unique to the B2 (angled more because of the
handlebar shape)
Throttle cables are about 1" longer (unique to the B2 to accommodate the
taller handlebars)
Front fender is shaped different (unique to the B2)
Does not have headlight ears to mount a headlight (these are usually hard and or
fairly expensive to find)
Seat is different as it's a two piece seat instead of a one piece (rear seat
mounting brackets interfere with one piece seat if installed and must be cut off
for seat to close all the way)
Badges on side covers say 'Touring' ( unique to the B2)
Does not have stalk type turn signals or a place to mount them in the rear (signals are in the fairing
on the front and saddlebags in the rear. Signals mount to fork ears in the
front which you also won't have on a B2)
NOTE: On these newer browsers I've noticed that they don't always display my large images in full size when you open an image from the thumbnails. Once you click the thumbnail and open the larger image, if you 'mouse over' the image you should see a " + " symbol or some other indicator like a box with arrows usually on the bottom right edge of the image. If you click on the indicator, then the image will expand to it's full size which displays full screen on computers that use a 800 x 600 resolution setting for the monitor. If you click the indicator again it will go back to the smaller image. Some people use a resolution setting of 1024 x 768 or higher on their monitors and for those users the images will appear smaller than full screen in size. You can change your monitor settings easily enough if you desire. Also, the indicator I've noticed is slow to appear even after the image appears to of completely loaded. The indicator in Netscape seems to be a lot faster to display than the one in Internet Explorer.
