Motorcycle Speed from Gear
The basic technique of "Speed from Gear" is the same for any vehicle when you can get or estimate RPM, a total gear ratio between the engine and drive wheel(s), and the wheel diameter. You just take the Engine revs per minute, convert that with the primary gearing X transmission gearing X final drive (rear end) gearing to get Wheel Revs per minute, then find tire circumference and you've got Feet per minute, convert that to your favorite units (usually ft/s or mph for me).

One drawback with motorcycles is that the engine speed can range by a factor of 10 (say, 1,400 RPM chugging away, but 14,000RPM for sporty 4-cylinders at full-song). But if you can pin down the RPM, the technique is good. This enthusiastic rider thought by covering the MPH reading on the screen, he was protecting himself. I think this is a BMW S1000RR, showing their "Race Pro 1" screen mode. The video is here: https://www.facebook.com/share/v/19293gBtXF/

We see he's at about 10K in 2nd gear, then shifts to 3rd and lands at about 9k a few seconds later.

You can do the math by hand pretty easily, but the Gearing Commander website lets you pick the bike and year and auto-fills all the gearing specs. Be sure to confirm those for any analysis that really matters, right? That spits back a speed in third at 9k approaching 90mph. 45° and 80+mph is a combination few riders see.

Peace. -W
