That is a KZ400/KZ440 site standard. Think its called cycloputer.

I've got a Sigma bicycle computer on mine in addition to the regular gauges to show mileage, time on bike, speed, etc.  it was only $30 and I've gotten it up to over 80mph and it still shows the speed accurately compared to the speedo.
