Default Does this look right?

Good morning,
Does the RPM and speed look normal for my GS 300?
I do not have owner's manual and I'm just looking to see if the RPM is matching the speed seems kind of high but I don't know the shift points or if this is a normal range for the speed.
Thanks

Yes, that looks right. Should be knocking on the door of 3k at 80mph.

An 2005 GS 300 had 225/55/16 tires that turn 784 revolutions per minute at 60 MPH. (784 revolutions per mile / 60 miles per hour)
The rear axle ratio was 3.916 to 1 so the drive shaft will be turning 3070 RPM.
The transmission ratio in 5th gear is .753 so the engine should show an indicated 2311...give or take

ThomasGS4's (and my) usual speed of 80 MPH would be 1.33 times faster so would dial up to 3073 RPM
