Hayabusa vs H2R Top Acceleration & Speed

Suzuki GSX1300R Hayabusa vs Kawasaki H2R Acceleration And Top Speed

Suzuki GSX1300R Hayabusa vs Kawasaki H2R. Comparing top speed and acceleration data through the gears accompanied with Dyno curve and thrust curve graphs.

Hayabusa vs H2R Dyno Curve

– H2R – Hayabusa

The Suzuki GSX1300R Hayabusa makes 180 horsepower at the rear wheel produced at 9500 rpm.

Peak torque is very impressive 107 ft/lb at 7500 rpm while Kawasaki’s H2R stomps it on the dyno with 246 horsepower at 13000 rpm and matches the Hayabusa’s 107 ft/lb though produced at a higher rpm of 11500 rpm.

The Hayabusa dominates below 10000 rpm on the dyno and is a more usable and flexible engine but on the actual road, it is only stronger below approximately 6000 rpm in-gear which you can see in the below thrust acceleration curve. The H2R is much more explosive in the top end and makes the Hayabusa feel flat.

Hayabusa vs H2R in-gear Acceleration Curve

– H2R – Hayabusa

The above graph shows each motorcycle’s torque curve when translated through the gears. It’s the actual acceleration available to the rider in each gear and it is plotted against speed.

Due to producing more power and torque in the lower rpm range, the Hayabusa has more acceleration available in the first half of each gear.

This advantage could be more but the Hayabusa is geared much higher than the H2R so its bottom and midrange torque advantage is not as high as it could be if the Suzuki ran with lower or the same gearing as the H2R.

The H2R on the other hand offers much more thrust and acceleration in the second half of each of its six gears as clearly demonstrated above.

Despite the Hayabusa running longer gear ratios the H2R actually has higher top speeds in each gear, and this is simply due to the H2R being able to rev to 14000 rpm against the Hayabusa 11200 rpm.

Hayabusa vs H2R Acceleration through the gears

– H2R – Hayabusa

The GSX1300R Hayabusa and Kawasaki H2R are evenly matched from the dig, with the Hayabusa having the advantage. It is only when halfway through third gear and at around 120 mph which is where the H2R is able to translate its extra 60 horsepower much more effectively.

Though the Hayabusa has the H2R beat from 0-60 mph with a time of 2.77 seconds with the H2R trailing at 2.93.  The Hayabusa also beats the H2R to 100 mph dipping under 5 seconds at 4.95 seconds to the H2R’s 5.12 seconds.

The Quarter Mile time for the Hayabusa is 9.91@150 mph which is only a fraction behind the H2R’s 9.76 seconds though the H2R is hitting a terminal speed of 164 mph and really getting into its stride.

The H2R then goes on to achieve 0-180 mph time in only 11.77 seconds with the Hayabusa trailing by a little over 5 seconds at 16.81 seconds.
