Those aren't really a true top handle like a Stihl 200T or a Husky 235 .I've got three of them and the balance is all off .Back in the day they sold probably more of them for firewood saws than they did to tree trimmers although on that they were the best.They really aren't bad firewood saws .
Fact when I sold firewood for about three years an S-25 was all I had until I got a larger saw .For their size those things have a lot of power .
