One of the most desirable sportbikes of the 1980s, the Suzuki RG500Γ was in a class of basically two with the Yamaha RZ500. Powered by a two-stroke square four it shared with no other bike in Suzuki's lineup, the Gamma was intended to evoke their Grand Prix racebikes, which led to an interesting dilemma: two-strokes were still king in the racing world, but their smoky emissions and poor fuel-consumption were dooming them to irrelevance in the real world. And while quarter-liter two-strokes continued well into the 1990s, "big" 500cc two-stroke fours from Suzuki and Yamaha lasted for just a couple years.
The Gamma's 400lbs and 100hp weren't cutting-edge numbers even in their day, but the relatively light weight and 500cc power meant that, although there were faster bikes in a straight-line, the Gamma had that magical combination of agility and top-end hit that two-stroke fans find so addictive. Or maybe burnt two-stroke oil has some sort of narcotic effect? Sure, yesterday's Triumph Daytona would probably kill it in any quantifiable measure of performance, but what would you expect from a thirty year-old motorcycle?
Today's example is very sharp-looking and has been modified to use wider 17" wheels front and rear. Purists might balk, but finding sticky [and safe] modern rubber to fit those very skinny [120 wide at the rear!] stock items might be difficult and I think it improves the look of the bike, although aesthetics are certainly subjective.
