I believe they opted for the odd transition section to be able to place it directly on top of the original location of the speedo so that it is easy to install and would be compatible with both the Vit and Svart 701s. Since it bolts directly atop, it can go on both bikes.
Also, like someone else said, their original was designed integrated with a new top triple clamp, and that would have added lots of $$ to the price and would not have been compatible with the Svart.
I'm on the fence, but I purchased one. I almost certainly will modify the old location and design and 3D print a new holder. This design, while functional, is ugly. It is literally sitting on top of the face of the old speedo location. The plastic parts that hold the speedo are really cheap <$20, so to modify is no big deal.
I was hoping for more on the screen than what I'm seeing here - a simple circle with kph in the center? I hope there are other setup options . . . .
Regardless, I'm in.
