I have an app that records motorcycle seat vibration and shock. While doing a test run on Yamaha NMax I have observed shock readings from the seat that are inconsistent with the ride quality. The bike seems to ride smoother than the readings suggest.

What would be causing the bike seat to shake/vibrate at +/-1g acceleration? or is it under dampened suspension oscillating?

I suspect worn out engine mounts or thin seat cushioning. What else could be causing seat vibration while riding?

excessive seat vibration

Here’s what smooth readings should look like: enter image description here

  • Have you checked all those mountings - be a good first step.
