Not really a new smart mod but I was looking at adding a solar trickle charger to my bike after some problems with the battery. What I did find while investigating the power inputs and outputs on a S2R800 was the AUX power coming off the battery. One of my problems is on longer rides the last up to a week, I was finding it hard to keep my GPS, ipod and phone charged all the time. So my solution was $50 at Jaycar and 20min time, I have built a small black box with a water proof USB port that is connected to a car USB charger meant for a cigarette light 12v port. I have added a switch as the USB converter is always pulling a small amount of current, even if there is nothing plunged in. So the finished product is attached to the side of the bike inside the naked frame with velcro so it can be removed at any time. The on/off button lights up when the converter is powered on and the whole thing is water tight. If anyone is interested I will post pictures later. Its not a big mod but one of my first, so thought I better share.
