Hi, there.
That's almost same case as mine.
With GZ on Full Coverage, it's about $18 a month at the G internet company.
Asked them for my new bike Yami FZ6, they put over 2000.
It was ridiculous for it, new one is street bike not sports bike class.
I shop around and found P company, and it lows 1/3 of the G company's with full coverage.
I included all the options even though I don't needed it for the law requirements.
Still 1/3 of the G company quoted me, and changed it to P company, canceled G company.
I don't know why G company put that much money on it.... still don't understand.
I suggest you research more..
And good luck!
