A new heads-up display kit is now on the market from Motion Research. The display allows you to get your important bike information without having to look down at your gauges. The diplay shows RPM, gear, and speed, everything you need to know to perform as best as you can on those twisties.
the unit simply mounts to the top of your helmet and displays the info through your visor. No pricing info available yet, but I imagine you will see these things in your local dealer soon enough.
