Via MC News:
“Except the new R7 won’t be anything close to a fire-breathing 750cc four-banger. Instead, the CARB filing lists the new YZF-R7’s engine as 689cc – the same size as the current parallel-Twin used in the
MT-07,
XSR700, and
Tenere 700. This all but confirms the new R7 will likely be a fully-faired version of the MT-07 – or at least its engine.”
Motorcycle.com:
“Spotted by the eagle eyes at
Motorcycle.com, the CARB filing tips that the 689cc motorcycle will use the parallel-twin engine found in the
Yamaha MT-07.”
and in CycleWorld;
“In terms of specs, the CARB filings don’t give much away, but the emissions performance of the 689cc parallel twin is identical to that of the latest 2021 MT-07, which means it’s a safe bet that the power and torque levels will also be unchanged. That means we’re looking at a peak of 72.4 hp at 9,000 rpm, with torque maxing out at 49.4 pound-feet at 6,500 rpm.”
I’d say that the CARB filings would suggest nothing except the MT07 mill.
