Introduction to the Honda CG125
The CG125 model first appeared in the UK in June 1976. It
can be regarded in many ways as a utility version of the popular
CB1 25 with which it shares many features. The basic difference
between the two models is the CG125's use of pushrod
operated overhead valves in place of the more popular overhead
camshaft arrangement. The unit provides surprisingly brisk
performance coupled with good fuel economy. The machine in
general is functional and sensibly equipped, and does not suffer
the surfeit of gadgetry so often found on its contemporaries. Its
inherent simplicity makes it an ideal learner's or commuter's
mount, both in terms of ease of riding and in its ease of
maintenance. A noteworthy feature is the adoption of a full rear
chain enclosure. Although this is by no means a new idea,
having appeared and disappeared many times over the years
with the changing dictates of fashion, it is, nevertheless, an
eminently sensible feature, greatly extending chain life.
Despite remaining basically unchanged, the CG125 has
received several modifications and has been altered slightly in
appearance to keep up with its rivals. Five distinct versions have
appeared, with differences of varying significance, which are
identified (where applicable) in this Manual by their Honda
model code suffixes. Identification details, as available, are
given below with the approximate dates of import; note that the
latter need not necessarily coincide with the machine's date of
registration.
The CG125 model (no identifying suffix) has the frame
numbers CG125-1023061 to 1111090. Engine numbers are
not available. Identified by its shrouded, external spring, front
forks, this model Was imported from June 1976 to May 1978.
The CG125K1 model has the frame numbers
CG125-1114636 to 1162518. Engine numbers not available.
It differed most noticeably from the CG125 model in having
front forks with internal springs and exposed stanchions, and
was imported from May 1978 to March 1981.
The CG125-B model has the frame numbers
CG125-1202755 to 1223689; its engine numbers start at
CG125E-1374586. It can be distinguished from the K1 model
only by its different paintwork and graphics and was imported
from March 1981 to March 1982.
The CG125-C model has the frame numbers
CG125-1272831 to 1286692; its engine numbers start at
CG125E-1513928 on. Fitted with revised tail lamp, flashing
indicator lamps, handlebar switches and the usual detail
changes to paintwork and graphics. This model is also fitted
with a higher compression engine and the (T)PFC carburettor
for greater fuel economy. Note also that the ignition switch is
combined in a new warning lamp cluster, mounted next to the
speedometer. Imported from March 1982 to November 1984.
The CG125-E model has the frame number
CG 125-1288790 to 1293380 and the engine numbers
CG125E-1689761 to 1694851. Identical to the C model
except for detail changes to the graphics, this model was
imported from November 1984 to April 1985.
All the aforementioned models are of Japanese
manufacture and are covered in Chapters 1 to 6. Later models
were manufactured in Brazil and known as the CG125(BR)
models; refer to Chapter 7 for further information.
