Arrived really quickly by a proper carrier RedEx. Seems to work fine and such a good price. Only downside is that I no longer get a percentage battery state shown on the dashboard on the bike. It only shows the bars. Once down to one bar you can't tell how close you are to running flat.
Looks the same as my standard battery but fitting to a factory fitted battery it quite difficult to change over as The brackets are different and U have to solder the two wires. But I did it successfully and are happy with the result.
