I don't ride a motorbike, but visit the Insta homepage. For example, there is the "Motorcycle U-Bolt Mount".
I just know that I have to tinker with my bike. Otherwise the bolts come loose. And that is very unpleasant.

If you search for "selfie stick" on the Galaxus website, you'll find a wide range of models at all prices and for all uses. INSTA360 offers several models, in metal or carbon, with lengths ranging from around 70 cm to 3 metres. Be careful, however, with sturdiness, as the selfie stick can be caught in the wind when travelling on a motorbike, even if it is not vertical. Use on a motorbike should not affect the safety of the rider or other road users. It's a good idea to choose quality accessories, such as those from INSTA360 or RAM MOUNT. This is the way to maximise the chances of still having the camera in place at the end of the shoot. Even at low speeds, the more the selfie stick is deployed, the greater the swaying movements will be and the INSTA360 software will not be able to compensate for them. If the speed is increased further, the selfie stick could simply break. INSTA360 offers packs for different uses, including motorcycling. A small tripod can also be used to attach the camera, with or without the selfie stick, for beautiful, stable images as the motorbike passes or during stops. Enjoy the ride.

Hello, we don't know because we don't have a motorbike!
