I ride a 1982 Suzuki GS650G and I have to say it’s a great machine.

It’s got five gears, shaft drive, a fuel gauge (not fuel light), standard upright seating, turn signals, triple disc brakes, an oil tight four cylinder engine, four Mikuni carbs that never leave their balance, reliable electrics, single oil type and plug for both transmission and engine, electronic ignition, dash gear indicator, 4 way adjustable rear damping, front air shocks, under 500 lbs. weight and over 70 hp. Unlike other shaft bikes of the 1970s and early 1980s, the GS650G has a plain bearing crank, and direct drive 5th gear eliminating the drive slop, making a tight connection from the throttle grip to the rear wheel.
Now, what if Suzuki launched this bike in 1971, instead of 1981? My feeling is this would have taken some of the market amazement and business from Honda’s brand new and revolutionary CB750. There’s nothing on the GS650G that couldn’t be offered in 1971. We just need Suzuki not to put all its eggs into 2 strokes.
