Hi friends, I am studying final year Automobile Engineering and I should do a project as a part of academic system. I searched for many things but destined here and my take is "Stop Start system for two wheelers". I had heard that two wheeler giants are working on it.
1)IS this system already present in market?
2)What type of sensors would it require to build a working model?
3)Availability of parts?
4)Cost of this project?

working; The sensor should sense the speed and switch off the engine when the engine attain predefined rpm and starts when it reaches required value.
@#-Link-Snipped-# (It would be nice if you could post the approximate cost of speed sensors.)
Need advice about the feasibility of this project.

Also pour ideas on keyless entry in two wheelers(In my idea, it involves usage of swiping card to access the ignition switch.
