1200S Battery and plugs

Hi
My battery is problably on it's last legs despite showing 13 V. What type is it? I'd rather not take it ou just to check.
Another question, is there any special trick to removing the lower plugs? At 23k kms it might be a good idea to replace them or is it too early for that? The bike runs very well.Thanks

Can't help with the battery but you will need a long socket for the plugs. There is a tool for the cap but i used a screwdriver and it was easy. I was getting a small missfire and now and again Iit was only running on one cylinder after a good run and starting again after a short stop. That was 19k miles. Plug change fixed it.

I watched this video so that I knew how. Ain't YouTube great.

The battery's the same as my ST - YTX14BS, amongst other type numbers.

I fitted a Motobatt MBYZ16H, rated at 16.5 AH, CCA 240, which was the highest-rated one I could find...and reasonably priced at around £50. It has 4 terminals too, the 'spare' ones are very handy for any extras you might want to connect, rather than having to fit everything onto the usual 2.

Thanks for that. I very much need four terminals.
FWIW, if anyone else is interested; Tanya don't appear to keep that four terminal Motobatt any more but M&P do

If it matters to you, mine was black when it arrived....so much classier than that loud yellow they do...!

Yes. When I saw the pic I did imagine it on the bike and question their colour choice. I have since found it in black. Might call beforehand though just to make sure
