I'm an engineer also and there is something missing.... the rear fender. That was the whole idea, it's just a look. These fender eliminators are offered with just about any sport bike. You'll see a lot of them out there on the road like this. I ride this bike pretty much back and forth to work and short trips on the curvy roads we have in this area. I avoid the rain, a big baby I guess.
This type of thing may not be practical for long cross country rides or the daily rain or shine rider. I must admit I thought the kit contained a whole new rear fender assembly that I could save the old one in case I sell some day. By the time I received the kit in the mail I was at the point of no return. But it's what I wanted so it works for me.
