My C-7 is in the 80cc class. The C-9 is a little larger close to 85cc.
My C-7 doesn't have as much raw power as my 925. It also doesn't
have the RPM's. What it does is have, for what ever reason; is the
ability to keep its lower RPM with the longer bars when I push on that
saw.
Hard to quantify...if I have a 22-24inch bar, the S-XL925 will out pull and
out cut in every situation. Period. When I get a 30 inch bar on both
saws the 925 cuts really fast but will stall the chain easier if I push.
The C-7 doesn't cut quite as fast when both are on the power band,
but when I really push OR things begin to pinch, its harder to stall the chain
& therefore ulltimatly easier to use on the bigger stuff. The other interesting
characteristic my C-7 has is its WAY easier to start and has very little
vibration.
