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. 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
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.
