In the world of classic
automobiles, the term "proof car" refers to a time-capsule perfect
original that's so utterly unchanged from the way it
existed upon leaving the assembly line that it can be used as
"proof" of what is "factory original" for concours judging
purposes. Dennis sent these shots of his early-production
1969 KO that easily qualifies as a "proof bike".
It's hard to tell from this shot whether you're looking
at a nicely restored bike or a low-mileage survivor. Aside
from the distinctive contour of the original seat, there's
little that appears different from any number of restored
examples we've seen. But first impressions, especially via
photographs can be deceiving.
Here's a classic example of those little "proof"
details. Click on the photo and you'll easily see the tiny
black rubber plugs in threaded holes located between the
seat and RH sidebadge. The pair of threaded holes were used
for a lifting handle on the ST70.
The correct K0
sidebadge, plastic gas cap, short style early tank bracket and
original rubber battery cover are all there. Even the plated
hardware is all factory-new in appearance. Note that only the
engine sidecovers are painted, not the cases. The castings are
so clean that they could easily be mistaken for being
At less than 2
miles per year average, the engine should eb fully broken in
sometime during the 24th century(!) This is what a new
speedometer face looks like without the usual sun fading seen
on 99% of them.
The earliest production bikes had the tail light
wiring routed through a rubber- grommeted hole in the top of
the frame. The hole was relocated to the more familiar spot in
the wheel arch before the end of `69.
Another rarity, black
plastic brake levers. Very few made it into production before
being superceded by the familiar aluminum versions, probably
for good reason. Just one more detail only found on a
museum-quality, early production model.
Another oddity...the early
seat pans had the toolkit holder bolted in place, insterad of

black oxide finish.
OEM tires & shocks.
Note the satin finish aluminum lowers and no plastic tubes
below the springs. The buddy pegs appear to be generic
The earliest bikes
came with Z50 stator covers. Note how rapidly the paint
develops rub spots, just the nature of the
OEM seat cover & foam are almost never duplicated.
The seam spacing is unique as is the foam contour. Seats of
this vintage had latex rubber foam, which is almost impossible
