The little and spicy member of the Gamma-family
In March 1983 Suzuki presented the RG250 Gamma to show who's
the king of the road track and a couple of years later the RG125
Gamma was introduced to give a match to the Italian 125cc racers.
RG125 Gamma was introduced in Europe at IFMA '84, the International
Bike Show in Cologne, West-Germany, in late 1984 (see the picture
above). The bike at the show had only a 80cc engine and the
125cc version was to be introduced later. There's nearly no
market at all for 125cc motorcycles in West-Germany but the
80cc bikes sold very well.
The RG125 Gamma borrowed a lot from its bigger brothers, RG250
and RG500 Gamma but the single cylinder RG125 was very narrow,
making it almost impossible for the sides of the motorcycle
to touch the tarmac when leaning the bike in corners. The maximum
leaning angle is whole 55 degrees! The first model had only
105 kg (231 lbs) dry mass. Its steel frame was almost fragile
but it worked well. The brakes were good at the time and had
a great feeling.
Riding a RG125 Gamma is quite unpleasant experience for the
taller riders. The small dimensions of the bike gives a great
racing feeling but it certainly isn't a bike for touring.
The water-cooled two-stroke engine vibrates a lot and the rear
mirrors are blurry at all speeds. It delivers a lot of power,
though (25 hp, 19 Nm). For more powerful mid-range the engine
has a system called AEC, that opens an extra exhaust chamber.
Only cosmetic changes were made to the RG125 Gamma between 1985
and 1991. The 1992 year's RG125 Gamma was totally redigned.
The frame, the suspension and everything of the bike were better.
The engine was upgraded to deliver 33 hp at 11.250 rpm. The
new RG125 Gamma borrowed a lot from the RGV250. The engine can
be described a s a RGV250 engine with a single cylinder instead
of two. Even the 125cc engine got an electric starter and balance
axel to reduce vibrations.
A naked version called RG125U
Wolf was also introduced in 1992.
Note: The different measurements below may be caused by differencies
between different countries. For instance, the version sold on the Japanese
home ground had the engine peak power limited to 22 hp.

1985 Suzuki year
code: F
A model with a white fuel tank anf fairing was sold in some countries
besides the blue-white models. There were some problems in getting
started with the mass production of the RG125 Gamma, as it was
for the RG500 Gamma. The first bikes arrived to Sweden in late
1985 and were sold as 1986 year's model.
The RG125 Gamma models up to 1991 were sold in Japan without the
lower fairing (option) in Japan.

1986 Suzuki year
code: G
Because of the late start in mass production of the RG125 Gamma,
no new model for 1986 was presented in Japan. In many countries,
as in Sweden, 1986 was the first model year for the RG125 Gamma.
There are small differencies in the specs between model sold on
different markets. The wheelbase and tyhe mechanics are still
the same.
