Btw Grzegorz, I also have that very same Drag Specialties tachometer attached to my handlebars and with the Speedy's risers like you have there. However, I've found there's sufficient room between the top of tank console and the handlebars to attached that tach so that its bracket sits "upside-down" and thus sits lower and below the line of the handlebars and so that it doesn't block your line-of-sight to the speedometer.
You might try experimenting with this and seeing if you'd end up liking this arrangement better, also.
