    2015 ECU retains error codes?

    Hi, I'm looking at bike that had sat for while. Most likely battery has died. Does the ECU store error codes in non-volatile memory? Or are all codes erased when battery dies? I'm interested in any faults that this bike may have had before it was stored. Thanks!

    Winter Storage

    If I leave my RC stored over winter with no battery will the display information be lost e.g mileage, service interval etc or is the internal memory fitted with a sufficient back up battery? Thanks Andy

    WPS battery question

    Does anyone on here have experience with the WPS Li battery? I like the idea that it is stock size so no spacer is needed. Have been checking things off my list and a Li battery needs to be checked.
