So, that means the 063 bars weigh more...? at least the solid bars like ES.

Was that solid or laminated bars?Mike Maas said:
It fits what I thought would be the case with laminated ones, as the side laminates are the same, the center one beeing according to gauge.

Can somebody measure the width of a 3/8s and an 063 chain?

They were both 3/8's solid Stihl bars.SawTroll said:

OK, then I think it is pretty safe to conclude that both solid and laminated Stihl bars are .013 wider, and necessarily a hair heavier, in .063 than in .050.

Ok. I was searching for comments on difference in 0.050 and 0.063 chain and found this thread. It appears that there were some unanswered questions regarding weight and bar thickness. Here is some data I collected.
Chain#1 72 link, 3/8, 0.063, RS (sharpened once by file), weight = 365g
Chain#2 72 link, 3/8, 0.050, RS (never sharpened), Weight = 359g.
As you can see, the weight difference is insignificant (1.7% to be exact). I don't believe this difference would be measurable in chain acceleration as the chain/bar friction would be much more of a factor IMO.
I also measured two bars I use, one an E and the other an ES.
Bar#1 20" Rollomatic ES #3003 000 9421, 0.063
Overall bar thickness = 0.175"
Weight = 1235g (2lb - 11.6oz)
Bar#2 20" Rollomatic E #3003 000 8921, 0.050
Overall bar thickness = 0.175"
Weight = 1063g (2lb - 5.4 oz)
I guess we are not comparing apples to apples here, but it is worth pointing out that the ES bars are quite a bit heavier, 16% by weight in this case. One last point, I use these bars on an 034 and I can tell the difference in the balance/center of gravity with the ES vs. the E. Running the ES bar the saw gets ever so slightly nose heavy.

One thing I don't see mentioned here is sprocket life. Would it be correct to say that if .063 has a wider bar groove then it follows that you also have a wider drive surface on the sprocket and therefore longer sprocket life?

Default guage on 14" MS180C in USA is 0.043 and in UK is 0.050 (I may have these the wrong way round). I suspect maybe its Stihl trying to guess what kind of trees you might live near from the region you purchase the saw.

You have it around the right way. The .043 chain is type PMN 3/8. It's a low profile narrow kerf chain and cuts like butter - about 20-30% better then the .050 chain. It's part of what makes the MS180 work so well.
Interestingly, the 200T can take the same 0.043 bar and PMN chain, but the chain is not "rated" for use on this saw. I know a couple of guys that cut with it and they are sold... and the most interesting part - if you look at the 200T side cover, it doesn't fit correctly - there is a small gap at the top near the front. Put a 0.043 bar on, and the gap dissappears... hmmm, wonder what bar the saw was actually designed for.

No real surprices there, but it is nice to have it confirmed. I am pretty sure that the weight difference has a lot more to do with ES vs. E, than with .063 vs. .050.v8titan said:
I have weighted a few laminated bars, and I have found that the Rollomatic E is notisably lighter than the Oregon Pro-Lite also (15-18" bars).
