Meguro 170cc : DA Ranger

Meguro 170cc: DA Ranger, which debuted in July 1960.
This model, 125cc: CA Cadet The specification and positioning of the bore of the engine 
and frame were essentially common.
Production planning was based on 300 units per month, 2432 units have been produced by 
July 1963, considered about 3,000 units were produced around the year '64.
Originally planned as a sports model with an air that, when presented at the 1959 Tokyo 
Motor Show was the prototype of the specification called scrambler type.
When mass production, however, is changing the concept seeks to provide a small bike for 
the price of the 250cc, 250cc performance at prices that are close to what was 125cc.
Engine type DAH, a single-cylinder OHV 4-cycle 164cc.
As above, but may be seen from the engine specification and CAH bore up of the CA, which 
has its own characteristics in detail.
To improve instruction by the dynamo in the cell CA, but you have been equipped with a 
manual decompression mechanism, the support of the expansion of emissions due to 
compression resistance, improved startup time operation (for manual in CA , is said to be 
difficult and the timing of cell operation), so start as soon as new cells in DA, Meguro 
developed to act automatically decompression, decompression with the mechanism adopted by 
electromagnetic actuation.
"Magnetic valve lifters' unique patented mechanism called Meguro, start the motor load 
current value of the cell (100A in DA) and detected by the circuit during lifter relay, 
the relay will operate in excess value.
Solenoid circuit is configured to actuate the mechanism by which decompression.
The launch of the solenoid, the engine was equipped with decompression lever head 
(removing the compression pressure in the combustion chamber exhaust valve push down forcibly. 
From existing CA) was pulling a cable wire work.
Cell load is reduced because the motor if the engine starts, lower than the specified load 
current value, starting circuit of the solenoid to release the relay will operate the lifter 
to OFF, the decompression will be automatically canceled.
The mechanism of this cell will start with simple decompression, the idea was to reduce the 
load on the battery can also start with a cell simultaneously.
This equipment has been adopted as the S7 features had been improved at the same time our 
main product is installed according to the cell with the electric motor and 12v-DC.
After the AT, S-8 SGT and to SG, that is installed as standard equipment on models equipped 
with the motor cells.
However, the utility is questionable how much I was effective.
OHV Originally started in poor compared with OHC, is a burden on the motor as big as a large 
load on the battery by working beyond expectation decompression solenoid mechanism, many also 
work well because of the complexity or defect. 
Users actually called to make the less.
The thought that many users Meguro enough kick start even the 500cc class, may have been 
unnecessary and excessive equipment.
The difference between CA and elsewhere, a different perspective for the operation of the 
wire cable that connects to a decompression lever.
CA is a manual, and the wire is drawn upward from the engine head with a lever handle. 
Also, since the wire is fixed to the status of the head, that is actually moving the 
decompression lever to the cable outer wire.
In DA, it is placed below the engine decompression solenoid to operate the mechanism, 
the cable wires are drawn from the bottom of the engine head.
From a common head is fixed to the outer stay in DA, the original operating system has 
become a decompression lever to move the wire.
Differences in appearance, the CA is an S7 Leitrim in light cases, with a collar is like S3 
and S-8 in the DA.
Common in the fuel tank, but for the CA domed forms kneepad, the DA triangular type (there 
is a slight angle) are changed in subtle but.
Also, in a thicker rear tire size 3.00x17-4, which may improve the driving surface. 
This was a common specification is feedback to the CA.
Doubt that there is a difference in the change pedal.
Have become popular with the general change pedal lever back without stepping forward with 
a Advance 4 step rotary in CA, why transformation is an expression in a seesaw DA.
In stepping back heel is in the ankle area, not on impressions by magazines of the time 
"not use pedals," which is attached with harsh criticism. 
DA is very noticeable that there in no Meguro, evaluation of the bike easy to handle and 
surprisingly well-balanced performance, articles in magazines of the time impression. 
Is considered to have potential applications that can leverage business applications to sports, 
in March 1962 survey on the bike equipped fitness for purpose of the SDF, was chosen along with 
the Honda 150cc bike, the samples were delivered to the agency that. 
This was not adopted, was a military toehold in the motorcycle since the first of a 500cc: Z97 
commercial Meguro Motorcycles. 
The DA is allowed versatile units have been exported overseas, following the CA. 
In 1960 after the sale has produced 119 units, 113 units have been exported and the units of 
which 76 are distant from Japan over to Pakistan. 
DA seems to have been an aspect of a car exports enabled. 
The existing bike, still less.
