Spending my free time when the road is nice on the bike of course the thoughts of a motorcycle app is never far from my mind.
I always check the app store to see something social for motorcycle enthusiasts more in tune with the ADVrider crowd and less attention seeker crowd.
Going through the iOS user guide lines concepts like this are some what attainable.
This app concept is basically an achievement based system for your bike similar to Xbox/PSN achievements with a social hook. Willing members join up and just try to get more points that others based on distanced traveled, maintenance done and modifications completed.
