Nothing wrong with an 80cc on a 25" even a 75cc will pull it. An 85cc will piss a 30" bar
 
Don't know owt about 500i
 
Plenty of people have run a 25" bar on an 044 and it pulls it fine... 

That's my point.
I ran a 440 25" bar buried in oak,
My 461 run a 30" bar,
Why would I run a bigger heavier slower saw on the same bar?

Because it won't be slower, it will be faster.

How? When the 500i hits wood it drops to 10krpm.
Whereas the 461 holds 11-12k in the wood.
On a 25" bar.
I'd like to see them side by side on a 30" bar, the extra torque of the 500 should come in to play.

I agree. Day to day I leave 25 and 28inch bars on a 660 and a 064. They run lovely on them and aren’t unwieldy.

Are you genuinely arguing that on the same sized bar the larger powerhead won't be faster?

 

A 261 or a 441 on a 20" bar?

 

It might not be your cup of tea but there's plenty that prefer a saw that cuts timber quicker and don't mind the extra weight.

My 661 outcuts my 880 on 36" bar
Look at the rpm and torque.
I use big saws every week.

 Good for you. That rule doesn't apply across the range though does it?

 

For your argument to work the chain speed to torque ratio would need to remain constant through the saw ranges. You've simply picked the one example that supports your argument.

Your Chainsaw experience is measured in months ,not years as I understand it?

 

There are contributors to this thread who's experience is measured in decades.

 

Why don't you shut up and listen?

Have you read the advanced chain sharpening thread?
[emoji23][emoji23][emoji23]
Started in 2007 chum.

I run big saws every week.
I've used nearly every modern chainsaw produced by husky and stihl.
And a lot of dinosaws too.
Have a look through my hundreds of posts at my work.
Maybe it's you who isn't grasping the concepts I'm putting forward.

There is a limit to how fast a saw will cut.
I'm on lunch now but I'll put up something later.
