did you note down the voltages and if so what were they?

Nope

Felt and sounded laboured and reluctant, a couple of times it didn't start at all.(This is a bike I ride every day but only happening recently) Since changing the battery it's been literally razor sharp on the button every single time.

For reference the old battery of questionable age is a Yuasa YB9B 9.5AH 115CCA the new one is a BS Battery BTX12 10.5AH 180CCA

**I do believe having consulted the mighty google, that the standard pointy battery should be a YTX12-BS,12V,10AH with a CCA of 180

i'm concerned about the high voltages. it should not be that high. this will kill your battery. i'm leaning towards your RR being dodgy.

BTW even with nothing 'on' with my gizmo the gizmo is 'on'. when you turn the ignition on the gizmo comes on. for a laugh disconnect the gizmo even though it should not matter.

Whilst you are doing these jobs take the Starter Motor off and strip and clean it and bare the areas where it grounds to the engine making sure there's no corrosion,paint or grease there and the Positive pole connection is good and clean.

It's an often overlooked service point but can pay big dividend on engine starting.

Replacement R/R tested and fitted this afternoon. Voltages back to well within healthy ranges, chucking out a lovely 14.5v @5000RPM.

Static and idle voltages in the 12.8 - 13v region and just over 12 on ignition. Luvverly
