1971 A good year for Kawasaki. Some new bikes like the
F6 to F8 Enduro bikes. The last year for some like the A1 and A7 series. Here
they are:
75 - 90
cc Bikes
75 MT-1 Mini
Trail
The smallest Kawasaki this year, the MT-1 It was called Dynamite in some countries, and Mini Trail elsewhere, the last one probably the best name. The bike was made very compact with folding handlebar and the fuel and oil vents could be shut so it could be transported in a cars trunk. Power from the 75cc two stroke was 4.2 Hp, it had three gears, centrifugal clutch and the color was Lime Green. This really nice one was found at BIKEPIC. The MT-1 was in production from 1971 to 1975 with only minor changes. It was replaced by the KV75 in 1976.

GA1A and the GA2A where both updated versions of the 1970 GA1 and GA2. They all got a more modern look, with new seat and front forks, most significant update was the new petrol tank. There were new colors Pearl Candy tone Red and Pearl Candy tone blue.
The GA1A had De Carbon (Sealed-in nitrogen) type rear shocks. Enclosed chain case. It was in production from 1971 to 74
Colour:

10.5 HP @8,000
rpm, and 4 gears. Top speed around 100km/h. Read more about the different gear systems here:
The
GA2A A slightly modified version
of the GA1A, with
five gears,
different
coloring and
chain case. Made
from 1971 to 74.
Output was 10.5 HP @8,000 rpm. The GA2 remained in production to 1974. The GA2A had a top speed of 110 km/h thanks to its 5 gear.
G3SSA
The
G3SSA replace G3SS from 1970 The bike was modified to look like its bigger brother the A7 models. The petrol tank was new so was the side cover seat and chain case. This years color was Light Yellow and Bright Orange. The 90cc rotary valve engine produced 10 horsepower at 7500 rpm and featured a rotary 5-speed gearbox with disc valve induction and stainless steel fenders. The G3SS was produced until 1975 and was replaced by the KT100 in 1976.
GA3 90SSS
Bush Master
The
GA3 or Super
Street Scrambler
90SSS was made
for the Japanese
domestic marked.
The bike was a
scrambler
version of the
G3 above. And it
mostly got the
same updates as
the G3SSA. Have
found very
little
information
about this bike,
so if anyone can
help me out here
it would be very
nice.
Compare this
bike to the
GA3TR below, the
GA3 had low
front fender,
dual clocks,
different side
covers and 10cc
less, otherwise
they where much
the same.

The Coyote was a real mini bike. It started life as a 50ccm 2 stroke in 1969. But the small engine wasn't the best so it was for 1970 replaced with a 134ccm four stroke Bridges and Stratton copy.
You can read more about it at Mini Doodle.

bikes
F6 125
The 125 F6 was
introduced in
Japan late 1970
as the 125 TR
and was given
the name Bobcat.
It was
introduced
worldwide in
1971 as the 125
F6 or 125
Enduro.
The F6 looks
much like its
bigger brothers
the F7 175 , F8
250 or F5 350.
Actually the F6
and F7
shared the same
chassis and
running gear.
The F6 had no
Hatta
fork and a
smaller 18 inch
front wheel. The
engine produced
14.5 hp at 7500
rpm. A good
looking bike.
The F7 175 cc, same bike as the 125 except the 175 got the Hatta front forks like its bigger brothers and a bigger 19 inch front wheel. And the front fender got a nice black flapper. Power was 18 hp at 7500 rpm. (The picture at left says 21.5 hp.....)
Bothe bikes had
dual instruments
with speedometer
and tachometer
with nice rubber
hoods. The gas
tank could
easily be
removed by
removing a
rubber strap. A
forestry
approved spark
arrestor was
standard
equipment. All
off-road bikes
from the F6, F8
to F5 had
two spark plug
holes in the
cylinder head so
you can carry a
spare spark
plug, nice on a
two-stroke. The
rider could
adjust foot pegs
heights. There
is a five way
adjustable rear
shock absorber
and both bikes
have Kawasaki's
Superlube
automatic oil
injection
system.
250 F8
Bison
A new model for 1971. (late 1970) Named F8 Bison and a smaller brother to the F5 350. Its heavily based on the 350 and looks like a copy of the 350. The engine had 23.5 hp at 6800 rpm and 5 gears. One big new feature was the new Hatta front forks. The forks offered three adjustable axel positions and it was possible to raised or lower them around 100mm. And there was a three way spring preload adjuster. All together 27 different settings, not bad for a bike from 1the early 70's. You could also adjust both foot pegs and brake levers. The gear selector could be used on both left or right side sins the gear selector shaft protrudes from both sides of the engine case.
Wheels were made of alloy and the tires had trail pattern. It was a good looking bike! The F8 was produced from 1971 to 72 and was replace by the 250 F11 in 1972 (late 72). Color was Bright Orange/Ivory
All the pictures of the F8 (two different bikes) was found on the Marbles Motors web site. They have restored this bikes to a very high standard. There are more really nice bikes at Marbles Motors, you should take a look, link at right. >
250 F81M
The Motocross version of the F8 was called F81M. Not a real motocross bike, it was to heavy for that, but it still was lighter and the most capable big bore motocross bike from Kawasaki in 1971. It was only produced in 1971, the engine had 27 hp at 6750 rpm. The color was Lime Green
350 F5 Big Horn
The biggest of the F series, the F5 Bighorn 350. In its second and last year of production. It was replaced in 1972 by the F9 350. No changes this year other then new colors and marking.

The front forks got a stiffer spring and stronger return damping. Rear shock absorbers are new with much improved damping. The result is improved high speed stability.
Oil pump cable and left hand side crankshaft oil seal have been modified to archive better reability.
Earlier CDI units had trouble keeping water out ant it casing didn't stand up well to hard use. The new CDI are modified to withstand water and it also got better components and its casing are stronger built. On the drive train the new H1 got a stronger rear chain. And there was a new petrol tank, the color this year was Candy Tone Blue. The model name was H1A

W1SA
More
information
about all the W
bikes here:
The W1S had a rather big update for 1971, becoming the W1SA. The most significant update was the movement of the shift lever from right to left side of the engine. Same place as all bikes today have. This was done with some nice mechanical levels on both side of the engine.
There were new colours, the chrome gas tank was gone and new side engine covers made the bike stand out from earlier versions. Brakes was updated, up front a bigger more advanced drum brake guarantied stopping power. The rear drum was much the same as before, but painted black.
Actually a lot of parts was updated, new instruments, new front and rear lights, new indicators and new rear shocks to mention some.
Sill a popular bike in Japan but the engine configuration was an quite old construction at this time. The W1SA was not exported as the earlier W2SS and TT Read more:
