Do you use your phone on your bike?
IMO the motorcycle specific GPS has been made obsolete with the latest generation of smart phones. Just got a new LG6 and it is water resistant, at least as much as high end motorcycle specific GPS units, and has amazing battery and charging performance. It also has similar screen dimensions and a sharper screen than the high end GPS units plus it has the capability to function as a great video and still camera off the bike with dual lens. When combined with a bluetooth headset you get GPS voice instructions, music, and of course phone functionality.
Motorcycle manufacturers need to offer blue tooth bike/phone integration with a corresponding app, to allow display of monitored and also easily calculated values (with motion sensors on phone) such as engine tempature, ambient air tempature, error codes, exact rpm, acceleration, braking performance, dyno simulation, lean angle, corning G force, gear selection, etc.. This would be extremely cheap and easy to do with existing technology like $1 blue tooth chips. Some of this is already available such as lean angle reporting without bike connectivity with apps like Pirelli Diablo Super Bike app which is free. They could also offer handle bar controls similar to what cars now offer on their steering wheel to control music selection, phone call control, etc.. How about after market handle bar mounted phone controls?
