No information there but 65cc might be possible as the TS400 was that size.

I guess the TS400 65cc example doesn't mean anything as the TS500i was only 72 cc.
The MS500i is 80cc.

It could quite possibly turn out as a fuel injected "i", or a variety of options. Rumor mill from the same source says new 880 or 881.

stihlguy just told me this =   I saw a prototype of this unit while at training at STIHL. It was used for straight gas seizure training and at that time it had a ceramic coated, magnesium piston. There wasn't any real benefit to the ceramic coating apparently, so now it's solely magnesium.
It wasn't clear if it would replace or stand along side the 362, but it does utilize many of the 362 components.

Man if those specs hold true and she rips. That 400 going to be a winner.

12.8lbs PHO  66.8cc  5.4bhp seems like a winner. What I thought of was the ole husky 266 66.7cc almost 12oz more PHO.

Guy I know from racing days. He is in the FB chainsaw repair group in the thread. = The one I tested had a 25 on it. Didn't have any issues falling medium sized oak and hickory. I'm calling it the 362 Super as it shares majority of the parts. It does spool quicker and recover revs faster than a 362.

Some info from a guy from Norway running the 400 881. 70" plus bar on 881 === I have used the 400 and it is a stonking saw. Really aggressive and pretty light. I thought it was more of a replacement to the 362. A little bit heavier but considerably more poke.
Also used the 500i and the 881. The 500 has been out a while in Norway, seems a good saw but I wonder how long it would last in a logging scenario.
The 881 we used for a bit of milling. Seems to be a good saw but hard to tell what it would be like. We had a 70+” bar on it and a Panther chainsaw mill. It was pretty heavy.

I just use the website to store info from the chainsaw repair group FB I created.
Everything went social media and forums are just dead anymore IMO.

I wonder if any truth to this? So cool if no smearing. Copy paste =

(((((The Mag piston isn’t for weight reduction as much as it’s for warranty issues. That info is coming form a licensed Stihl dealer and tech who attended the dealership meetings at Stihl USA.

It seems that Mag won’t stick to Nikasil like aluminum will. So any overheating/straight gas/other user issues result in a scored piston with no meaningful cylinder damage at all. Another piston can be popped in and the saw can be run again.

Again, that’s info I got from a very reputable source.)))))

I find it hard to believe since the MS400 was just released for sale here not long ago .
But rumor is the Stihl 400i version suppose to be out there getting tested.  Suppose to be some in US too.

 IMO they are trying to go the route cars did. To slow up the shade tree mechanics from working on everything so you have to pay the big bucks to get looked at.

Pic just for attention.

STIHL manufactures handheld outdoor power equipment. Its equipment is tested extensively, including the testing of prototypes before series production models are built and released to the public. Such prototypes are not approved for general public use or sale. Equipment and prototypes are collectively referred to in this agreement as “UNITS.” The under-signed has agreed to test UNITS provided by STIHL, personally or by his employees (collectively “USER”). In consideration for USER’S opportunity to test the UNITS free of charge, USER agrees to the following:

1 USER will perform testing without any charge or fees to STIHL.

2 The UNITS will remain the sole property of STIHL, and are provided on loan to USER. USER will not share UNITS with any third party without the prior agreement of STIHL. Any approved third party will be required to sign an agreement similar to this one.

3 The fact that USER is testing UNITS, as well as the technical details and appearance of the UNITS, must be kept confidential –even after the end of this agreement. Additionally:

      o USER must securely use and store UNITS to protect against loss, destruction or damage, especially by third parties. This includes storing and locking the UNITS when not in use.

       o USER must NOT publicly exhibit UNITS or use them at public events.

       o USER must not make or allow others to make photographs, videos or other forms of media unless specifically requested by STIHL.

       o USER must NOT open, dismantle or repair UNITS unless agreed upon or authorized by STIHL.

       o USER will not intentionally or negligently damage any UNITS.

4 USER will only use the UNITS as instructed by STIHL and STIHL field testing personnel. STIHL will provide instruction manuals for series models, and instruction manuals for similar products in the event a prototype is being tested. For any additional features on a prototype, STIHL will give more specific instructions.

5 After completing the testing, USER must return all UNITS, along with any provided documentation as may be specified by STIHL.

6 USER will be liable for breaching any of its agreements in this document.
I agree to the above Terms and Conditions.

Guess I havent been keeping the info updated here.  Seems there is lot of issues.

Older info on CRG FB.

Newest today.

5 saws 2 months to under a year of use.

RLee
The ring stop on intake side of piston is centered with intake port on the jug. Top ring breaks right at the stop. After some wear on cylinder wall and the rings it’s letting that ring come out far enough that it catches on the intake port and snaps it. I’ve got 5 engines in my shop from rebuilds that all look identical.
