Here's the speederbike in the repo, the swoop is 3 down from it
Speederbike stats, not the default7/num1 and default10/num2 values
Compared to the swoop ones
iirc num1 contributes towards the max speed, while num2 is the min speed. You can see that the values are slightly higher for the swoop than the speederbike. Let's compare it to the X-31 Landspeeder for a little more contrast.
and you can see the numbers drop for the slower landspeeder
Hope this helps. Turn rate, acceleration etc can also be changed in here.
