I test-rode 3 Zeros in 4 years... I liked them but that was all. No 'spark' (pun intended).
I test-rode a LiveWire demo bike last year at a dealer event where I was able to ride it 5 times in one afternoon - other riders shunned it for the trad V-twins - and I loved it. The acceleration is excellent. The finish is superb. It's a Harley game-changer for me - like my '04 Vrod was compared to my 90s' Dyna.
Did I mention before it'll be my first new motorcycle ever (and of course my first new Harley ever). Oh, I did? OK then :-). In 2019 I sold 2 of my other bikes to afford it. Been waiting since then. And keeping lurking-track of lots of info out there.
BTW: there are no Zero dealers and no Zero support in NZ. There are no Energica dealers and no Energica support in NZ either.
With the LiveWire, I get dealer support and a 2 year warranty (yeah, 4 hours' ride away but, hey, at least the dealer's on the same land mass and in the same time zone :-) )
I have read a lot of the feedback (of course) from owners as well as non-owners.
You be you, I'll be me :-)
