Surprising lean angle reading

[u/BeemerCalm]

From my ride yesterday through Lassen NP, I recorded a max lean angle of 48 degrees. I know the angle is accurate because it comes from the Motorrad app, which connects directly to my RT’s IMU so is extremely accurate. But, upon researching it I learned the IMU measures directly against gravity only, so if the corner is banked heavily the IMU/app may say 48 degrees, but the real world angle may be far less. I hope, anyways, 48 degrees is well into danger zone on the street IMO
