Wondering what speed the mt hits redline. I've tried to catch it in videos but haven't been successful. Can any new manual owner stay in second and let us know what speed you are at when hitting redline? I'm in the US so mph is preferred but no worries if you test in kph.

If my math is right, it should be ~69 MPH (nice) @ red line in 2nd gear on the MT.

Assumptions:
  • 7000 RPM red line
  • 26.7" tire diameter
  • 3.46:1 final drive (MT only)
  • 2.315:1 2nd gear ratio (MT only)

Speed vs RPM is a linear relationship. If you know the RPM and speed at any point in 2nd gear you can easily calculate what the speed will be at redline.

This is correct. I just looked at my WOT in second gear haha.

I was going to say, just do the math. Fun part about that is you can see how your gearing changes based on tire changes.
