If you have a way to "punish the misbehaving motorcycle riders" while allowing or even welcoming the rest, please share.

We've researched this. It's a European wide issue that's discussed, researched, tested and so on, throughout many communities and places. So far, there's no way to prohibit only the bad actors.

Part of the "infrastructure" changes would be things like speed bumps. Where it pays off to ride below the speed limit, and hard to ride above it. But that then makes some misbehaving drivers use their "0-100 in 8 sec" that their motorbike builder once promised. Going through four gears on a 500m stretch. The disturbance and noise gets worse then.

It gets harder because many solutions will harm all the other legitimate usage too, or harm them worse. Speed bumps and farmers' harvesting with large tractors are terrible for our houses that then literally shake on their foundation.

If, like us, you look at "motorcycle riders" as a community, it makes sense to point at that community and say: solve the danger and disturbance that those few amongst your community clearly pose to others. Because the alternative is that we'll have to "punish" your entire community.

New people will always be popping up to misbehave. Addressing the problem at the infrastructure level is the only way to ensure it's permanently solved.

Kind of like "why would you want to build a pedestrian bridge instead of just jailing the driver who hit someone at that intersection." The odds that it'll be the last time are basically zero.
