The Suzuki RG250 Gamma was a two-cylinder parallel,
In its five years of production the model underwent three major changes:
Mk1 (1983–1984): 45-46 hp and 38 Nm torque. Very first bikes had a single
Mk2 (1985): Revised front fairings, mudguard and colour scheme and a slightly shorter wheelbase (from 1385 mm to 1360 mm)
Mk3 (1986–1987): Introduction of Suzuki's AEC system (Automatic Exhaust Control). This gave the bike a higher (around 49-50+hp) power rating.
(AEC system: Same idea as the now standard power valve design, but using a 'butterfly flap' to open and close an addition chamber on the cylinder head (open @ low RPM, closed at higher). This effectively expands the exhaust system at low RPM, to allow the exhaust to be tuned for high RPM. The AEC system opens at around 7500 RPM)
Mk4: (1987): There was also a very short-lived Mk4 version created for the Japanese home market, which had larger front discs, thicker tyres and larger diameter front forks. This model was never exported.
The RG250 Gamma was replaced by the RGV250 Gamma (V-Twin) in 1988.[3]
