Homelite Super XP1020 & XP1020... bar max length?

[Den]

Went to Mike Acres site and researched the Homelite Super XP 1020, and it is said to accept a maximum of 60" bar.

On the other hand, the Homelite XP 1020 is said to accept a 30" maximum bar.

Seems to me the regular XP 1020 should accept at least a 36" or 42" bar, since the Super XP 1020 and the XP 1020 are both 100 cc chainsaws. Am I right?

Why the disparity in bar lengths between two 100cc saws that are seemingly identical?

Both the XP1020 and Super XP1020 are direct drive 100cc saws, but in that same series is the 1130G.
The 1130G is a gear reduction drive and can pull a 60" bar, due to the lower chain speed and higher torque.
I can bury the 48" bar on my 1130G and pull up with both hands and still can't the saw to loose RPM.
I'm guessing that the max bar length for the 1130G was used for the Super XP1020.

I think 36 to 42 inch would be max with .404 chain on those old 6 cube direct drive Homies & Macs. As John said, the big geardrives will pull 60". I had an xp1000 and it was the same 6 cube power as a 1050 from what I could gather, yet it was rated for a smaller. The7-29 was rated for a 72" bar yet the 8-29, (same saw, different starter) is only rated for 60". Why?

So the question remains: Why does a Super XP 1020 run a 60" max bar, and a XP 1020 run a 30" max bar ? (As shown on Mike Acres site.)

They are both direct drive, both 100 cc chainsaws.

Probably a misprint somwhere.

I have had 4 Super 1050's and every one that has run one says, "this thing wants more bar!" That's with the 36". I haven't done any research, but if the older of the two says 60" and the newer of the two says 30", maybe they had a lot of failures with the 60"? If it's the other way around, or they were concurrent, I have no idea.

The 7 29 and 8 29 have different gear on drive belt. That's why the bar size differnce

It was my understanding that the belt pitch was the difference, not the ratio.
