Cycleworld dynamometer measures the maximum power output of Suzuki’s legendary 750cc in-line 4-cylinder.

The GSX-R750 from Suzuki has long been a track day weapon for racers and enthusiasts around the world. The GSX-R750 was first introduced in his 1985 and revolutionized the development of sport bikes. Now, the mid-range inline 4-cylinder sports bike has given way to a new wave of parallel twins like the Aprilia RS 660 and the Yamaha YZF-R7. However, the legendary GSX-R750 is still considered a good option when it comes to buying a sportbike.

The liquid-cooled 750cc DOHC inline 4 engine has long been a favorite in the cycle world because it can rev up like a 600cc engine, yet offer a bottom end as accessible as a liter bike. The Suzuki GSX-R750 hasn’t been updated since his 2011, but to see just how much this legendary Japanese sportbike can perform 11 years after his in-house, his Dynojet I wanted to run 4 cars in series with the 250i dynamo.

When the 2022 Suzuki GSX-R750 rolled off the autoscale with a curb weight of 428 pounds, it made 121.5 horsepower at 12,560 rpm and 53.0 lb-ft. Torque is 10,840rpm. The linear power delivery and relatively flat torque curve make the Suzuki GSX-R750 a very competitive track bike from club level to world supersport competition.
