does the 600 have a motor plate? im not seeing how the 858 is lighter otherwise, i get that necked down jugs weigh more than pistons but the jugs and rods are longer on the 858 right..
they say the 858 sits lower so must be in the mounting system no?
Correct, the 858 has the mount provisions cast into the lower case half and mounts directly to the chassis.

It would be really cool if the belt pitch is the same as the Gates/Mitsuboshi (sp) and aftermarket could just supply new top pulleys for whatever ratios we thought we needed.

Engine mounting, new simplified power valve system, different recoil cover, and it looks like efforts were made on the casting designs to keep them light on the 858 too. I'm sure it all adds up.

If my memory is still working those belts are a 8 mm pitch there are options but 8mm is a standard for this application.

OK, and how about the exhaust? thought i heard the pipe is lighter too. reports are that exhaust isnt shown on display 858s yet.

AC has been holding their cards pretty close to their chests on this sled with good reasons. I think the exhaust is either not production finished or there is something they don't want the competition to see yet. I was also told the exhaust is lighter. The display 858 is an engineering test sled so who knows? What I do know is these sleds are light with a low COG and I haven't been this excited about a new sled in a long time. These sleds are going to be awesome!

Sounds like same belt (or close to it) as my C3 belt drive on my 2013. Length is same. Bit wider by look of it though.
The Cat belt appears to be the same size belt as the TKI kit uses. The limitations will be the largers size gear that can fit in the case and how small the top gear can go without stripping teeth.

Looks like material can be removed and a big sprocket could fit. One would have to see in person. Good forward thinking!

Items of note for those of you that break stuff:

$442 - replacement 146 tunnel is pretty reasonable. Way cheaper than the $1700 I paid for a mountain cat tunnel for my 2014!
$48 - plastic running board replacement and another $70 if you bend the main edge support.
$1035 - front chassis clip.
$83 - Upper A-arm
$118 - Lower A-arm
$191 - Spindle
$170 - Belt Drive belt. (2.625 ratio by the way with 24/63 gears) Don't see any accessory gear part numbers in that particular window.
$86 - Main hood top piece.
Upper and lower half of the intake show unavailable and no price yet. This would be the part you'd break in a head-on with a tree.
$118/125 for side panels w/o decals.
$985 - 146 x 2.6 track
$1077 - 165 x 3.0 track (under the old M8000)
$3.50 - Track clip This is way better than the $9/clip they were charging for those of us who fully clip the tracks!
$525 - 146 rail

2.625 is extremely slow ratio. Do they use 3,5" pitch drivers or 3"?
Same gear ratio Cat currently uses on all their mountain sleds. The 3" paddle tracks are 7T 3.5 pitch. The 2.6" lug tracks are 2.86 pitch with 8T drivers I believe. So they aren't real small dia drivers.
