Maybe this will bring the thread back on topic. Stand in front of a Strom with conventional forks, preferably on a centre stand, and wedge a foot on either side to lock the wheel straight ahead. Then wiggle the handlebars. Look down and watch the tip of the mudguard over the tyre. Without a fork brace, you'll see the tip wander back and forth over the tread pattern. With a fork brace, not so much.
I rarely pushed a bike in turns or rode on gnarly surfaces enough to really feel the effect of a fork brace when riding. However, I felt the difference in wind gusts and I think a fork brace might have saved me when I chopped the throttle at a ridiculous speed on a Wee and created a tank slapper. That inexpensive addition could have saved a totaled bike, a hospital stay and pain I feel to this day. Of course, riding smart every minute instead of just taking a few minutes to see how fast the bike would go would have done that too.
