1986 Suzuki RG250 Gamma WW

By the late 1960s, two-stroke Japanese motorcycles were beginning to die out, yet Suzuki remained, continuing to manufacture new and larger two-stroke machines. It wasn’t until the late 1970s that Suzuki made the change and started making four-stroke machines on a larger scale. However, the two-stroke engines stayed alive on small and cheap machines, especially on the racing track. In the early 1980s, when Yamaha presented its RZ250R, a battle in the 250 cc class was on. The first strike was drawn by Honda, presenting the VT250F (1982), followed by the ambitious work of the V3-engined MVX250F. Yamaha and Honda were in the lead, although Suzuki knew their time was coming. Then came 1983, when Suzuki presented the legendary RG250 Gamma, which made people ask, who was the king of the hill now?

Many motorcycles have been called road-legal racers, but the RG250 Gamma was the first mass-produced motorcycle with a lightweight aluminium frame and racing-type aerodynamic fairing, starting a new trend that would become common in the industry. It was fast and handled very well, called “The Portable Racing Game” by critics. Suzuki had used all its experiences from the race track and its knowledge in designing 2-stroke engines to create something special and unique. The RG250 was a real road-legal racer and gained popularity in racing circuits. It’s not a bike for the faint of heart or commuters, but made for a track! The model was manufactured between 1983 and 1986 and was finally replaced by the V-twin-engined RGV250 in 1987.

The fourth model version of the RG250 was called the GJ21B, and it was released at the beginning of 1986. This version was largely the same as the GJ21A, with the only new addition being Suzuki’s new AEC System (Automatic Exhaust Control). This improvement allows a conventional two-stroke engine to reach a higher power output over a wider RPM range. This gave the bike an increase in its power rating (45 to 49hp).
