STIHL MS 400.1

[LuckyRookie]

The listed displacement of 62.6cc begs an interesting question in my mind: Has Stihl used the same crank in this new 400cm as they used in the 500i? because the throw on the 500i is 34.6mm and the most straight forward way to get to 62.6cc is that throw with a 48mm piston. This would be a meaningful (and unexpected) change from the OE 400cm with a 34mm throw and 50mm piston... any way to confirm this?

Figure out what the regular carb version of it is and you will have those specs. They say 363 same saw just with tunable carb.

Notice the HH they offer on both 363 400 now too. HC option too.

Also not a new 363 400 in pic they used.

I highly doubt they would use the 500I crank given the weights savings over the standard 400C.

Only other B+S I can come up with to get that smaller cc is 48.4mm x 34mm 62.55cc rounded up 62.6cc

Will the new 400.1 be listed as a pro saw ? The old 400 c-m was listed as larger woodcutting , In the USA.

According to rumors on the German-language Internet, they have abandoned the magnesium piston.

Damn cheapies…. That mag piston was one of the things that made the 400 so attractive. Not just because of less overall weight but less rotating mass… makes an enormous difference in how fast and smooth the saw winds up… (shrug) I suppose if I ever get one of these I can swap it out with a magnesium piston (if they’re the same bore) but ugh what a bummer (shrug)

Just seems odd to negate the benefits of the lighter piston and go to the smaller bore, which would just benefit the rotating assembly more. Really just seems like a bad move on stihls part. The 400 was widely accepted and has a good track record for being a new saw design.

+1 (that’s what I meant to say )
