The DT-175G was the second last
in a long line of enduro motorcycles that can be traced back to the CT-1 of
the late 1960's. Its demise in North America came in 1981 due to emmission
laws south of the border, but continued and evolved in other parts of the
world.
For North America, the 175cc
Yamaha series went through four evolutionary phases. The original bike was
born in the late 1960's and modeled on the DT-1 250CC, known as the CT-1.
These bikes were the first purpose built, dual purpose, motorcycles to come
out of Japan, and were very sucessful. They were dirt bikes with enough
lighting and instrumentation to make them stree legal. Most of them were
stripped of this equipment and used off road. With modifications they were
used in all types of off road sport, and were absolutely reliable, right to
the end of production.
The original CT-1 was a piston
port, two stroke, oil injected, five speed. It came with a low set front
fender more akin to a trials bike, and trials tires, most of which got
swapped for knobbies. When the model codes changed in 1974, the bike became
known as the DT-175. Other changes included engine upgrades including a reed
valve, a different fuel tank, a 21" front wheel, thermoflow shocks, and
basically a complete restyle, but a subtle one. This model run continued
until 1976 and when the 1977 models were introduced, the big changes were
revealed. 1977 brought the mono shock rear suspension into the fold, along
with a completely restyled bike, a radial cylinder head, redesigned engine,
and the whole package was a bit lighter than previous models.
These motorcycles were near
indestructable and were among the best to come out of Japan. When our
elected officials decided to close the door on these motorcycles, we lost
ten fold. In my case, i was in the market for a 175, and one night i saw an
add for one, a mono shock version. It was a cold saturday in january when i
went for a look. It was a complete, running bike and most importantly, it
hadn't been monkeyed with. So, i took it for a drive on the ice, and then
bought it. Spring came along with the realization that although it hadn't
been fooled with, it also never got maintained so well, and some replacement
parts were in order.
