SG,
It’s not a matter of feeling safe. It’s a matter of best practice.
I’ll admit using “wearing a helmet” is an over the top example of cost of avoidance. But it is an example of the point I’m trying to make. The clip ons on all the race bikes I’ve ridden and built had two forms of clamping; two sets of clamp bolts per clip on. The below the top clamp-S clip ons follow this principle; one pinch bolt and one anti rotation screw. The top-mounted clip ons with one pinch bolt and an anti rotation key are also an example of the two forms of safety though I’m not crazy about it. BMW has been making motorcycles a long time, I tend to trust their judgement on safety of operation.
In my career of designing, technical writing for, maintaining of and operating gas turbines, “jet engines” the rule of two forms of safety on critical assemblies was always followed. Torque and lock nut or torque and lock wire were examples of the principle. Multiple fasteners were required on control systems. Handle bars fall into that category.
