Is the 16" bare tool identical to the 14" bare tool, with the exception of chain and bar length? For example... are there any differences in motor size and speed, safety features, housing, chain break, etc.

Summary: Ego lists the same RPM, but HomeDepot lists different chain speeds (mps)

Previously, Ego listed two different speeds between the 14" and 16" saws (it was something like 6300 rpm and 6800 rpm). However, Ego appears to have updated that information on their website (have not checked if they updated the manuals) as both saws now list the speed at 6800 rpm.

The HomeDepot site also specifies a chain speed (mps, which is probably meters per second):

16" = 30.214" = 26.9

However, that still doesn't quite make sense to me... the formula to calculate chainsaw chain speed is : Formula for Chain Speed Calculation

- Take chain pitch and multiply x two.
- Multiply above number by number of teeth on sprocket of saw.
- Multiply that number by saw RPM. The number you get will be chain speed in inches per minute. To convert to feet divide by 12. To convert to feet per second divide by 720.

- 3/8 x 2=3/4 or 0.75
- 0.75 x 7 (number of teeth on sprocket) = 5.25.
- 5.25 x 12,000 (saw RPM) = 63,000 inches per minute.
- 63,000 divided by 12 = 5,250 feet per minute, 63,000 divided by 720 = 87.50 feet per second.

The other difference is the kit. The 14" comes with the smaller battery while the 16" comes with the 5Ah battery. The larger battery allows the saw to perform a little better as it provides more power.
