    an aftermarket rr might do that, but as I said, on both my bikes with stock rr's it's what I said...and I'm good with that...my 4 cars work the same way..

    We are all on the low side then at 13.5 - 14.3v according to those spec's, even those of us with newish bikes.  :187:

    My 2020 Tiger Sport has the last series 1050 engine with the extra oil gallery for improved stator cooling. From new I fitted a KOSO MINI3 voltmeter with the power pickup lead direct from the battery and the switched on/off lead to the left parking light. Voltage reading has always been between 13,9 - 14,1V.
    On my 2008 Sprint ST 1050 the stator failed twice. The RR 3 times. When the last RR failed voltage spiked up to 18,5V which burned both main beam light bulbs. It also had the KOSO MINI3 fitted.

    LOL - heading that way...

    I think the Tiger Sport models have a different reg/rec than the earlier 1050s, it's definitely a different part number and it's listed on the parts fiches as 'Regulator Rectifier, 50A', with the list of 'bikes this part fits' all relative recent releases.  I don't believe I have read of any failures on Sport models - unless anyone knows different?

    No matter what the RR, chemistry says you are damaging the battery above 2.4V per cell so the high numbers make no sense to me. An optimal lead-acid holding charge (as applied in major transmission and distribution battery banks that last for 20 years) is 2.2 V per cell. They are boosted at 2.4V per cell for short periods to mix the electrolyte. In our AGM case, that's not possible.
