2021 Sidewinder inner suspension wheels?

Do the new Yamaha sleds have wheels inside the rails where the rear shock attaches to? Reason I asked is I have a new Cat 137 ZR and it DOES NOT have 4 inner idler wheels only two.. I was surprised to see no wheels only a cross shaft where rear shock attaches? Not so sure I like this idea. Going to effect studding effectiveness and traction for sure.

21’s are the same like previous years, only inside wheels are the ones at the front.
On my 20 the two inner wheels are about to kick the bucket, rubber is starting to come off in chunks.. I ordered the JT wheels but they haven’t showed up yet.

Wait what? Previous years. My 17 has 4 wheels inside the rails in the middle of suspension. I must have missed the change.
Thanks for reply Fabio.

I just checked and it looks like they changed in 2019 to the inside 2 wheels and 4 on the outside.
