i know when i have done track days that i dont give a crap what my guages read. i know my rpm based on noise and the as the only thing i care about guage-wise when riding on a track. any other visual information could definately be distracting i would think. maybe for racing there would be some use with lap timing and that sort of thing. for on hiway/street riding it would definately be pretty cool.
I had this idea years ago. Would have patented it but I don't know a damn thing about electronics... Now this guys going to make all the money..
Your idea is good Rama, but bluetooth has a pretty limited range. It would be better to have a transmitter capable of being picked up by others as well.. like if you're on the track and your crew (like any of us have one).. could monitor your bike and see the same info you are. If it tied in with the central CPU on the bike you could get all the info you wanted. I think I'd rather save a few bucks and skip the gps.. go with just the bike info on the heads-up.
