TanyUK Battery for a 750 Breva.

Someone on here recommended a TanyaUK battery for my BReva 750.
I think after 4.5 years mine is on its way out but I cannot find the listing.
Does anyone know it?

I’ve just had a look at the TanyaUK site again and they list Moto Guzzi plus the 750 Breva so no problems , £85.00 inc if I need one,
£21.00 a year.
