I had an SR fork, and it was nice, but then I sold it and just had to deal with my stock forks bending occasionally. Now I don't land really sketchy, and now my stock forks don't bend. Was the SR fork worth it? Not really, but I did get lots of compliments on having a good looking scooter. Did a good looking scooter make me a better rider? No.
But on the other hand, if you bend your bars/forks every day and that messes up your riding, then you might want to invest in one piece bars/SR forks. They feel really solid and you can go bigger without worrying if you're going to snap your bars when you land. Having a solid scooter will boost your confidence in a way.
