Interesting video on Lean Angle

I saw this on another forum and thought others may be interested. I especially like the credit card analogy.

Interesting and pretty amazing.
Thanks for sharing

My kids were asking about lean angle when I first brought home the ST. I showed them this video.

Not a lot on the road when down at 64 degrees.

I would like to see something similar to all of the other degree angles they showed for contact patch area. It is pretty amazing how little rubber can be on the road and how they are able to stay in control.

This just really shows how amazing motorcycles really are. IT TAKES A LOT TO MAKE THEM FALL!!

I would say at those speeds and angles... It's takes a lot (of skill) to keep them from falling

Gives new meaning to "credit card limits".......

Did that video inspire anyone else to create a lean angle sensor with telemetry and logging? Or just me? I was thinking a microcontroller and an IMU would be just the ticket. But a modern smartphone has all that's needed too!

I'm curious to know how far I am leaning. I am not an aggressive rider so I know it's fairly shallow, but it would be interesting to have the data.

Thanks for sharing. Now I have a project to think about!

I have an app for my droid phone that is called Clinometer that measures level and inclination angle. All one would need is a way to properly mount the phone in a Zero position, meaning 0 degrees vertical. It shows the lean or inclination but does not record the data.

You should bring your project to the next step and also log you GPS location too.

There are similar apps for iOS but I don't know of any that record. That would be great. You really don't want to be admiring your lean angle readout while negotiating a turn. A RAM mount for the phone could be zeroed in close enough.

Add a couple of cameras with a view of the road: one on a gimbal and one fixed mount. Then have a video of all three displays. Get real trick and rig the phone mount to add an extra 10? in lean on turns. You know for bench racing purposes.

Not sure about the app you downloaded, but try a test of start/stop and see if it the change of velocity induces lean in the app. The only one I found that accounted for this in the accelerometer readings (I think) was the Pirelli one.
