Jenny Morgan did what I'm doing right now cross country + TAT on a Rallyraid equiped CB500X.
The Rallyraid-kitted CB500X is a cool bike, for sure:

... 487lbs as tested ...
Jenny Morgan's kitted CB500X tested
along with a late-model KLR in the Santa Barbara mountains:

(I will say that Jenny is trying to sell CB500X rally kits, so I'd
have to see that 440lb claim to believe it, even though
I'd love for it to be true ... that's why I tend to post
weights for race bikes, as being more reliable/believable ... if Yamaha USA
does not bring in the F7, I'd say it will be due--in part--
to the their belief that potential USA buyers will be too disappointed
in the F7's final real-world-weight ... the USA is living in a golden-age
of plated-dirt-bikes, and that has lead to unrealistic expectations of
what two-cylinder Adventure bikes can/should weigh ...

)
... having said all that

I'll be disappointed (and I'll bet
you a nickel I'll be disappointed) if the F7
weighs more than 450 lbs ...
not that I'm in the market for
a five-figure new bike ...
see you around
the campfire,
