A few quick things I noticed.

Dragon doesnt have a radiator, but a much larger front tunnel cooler w/ 2 inlets and 2 outlets (looks to be two separate cooling loops)

Piston is a different part number over the old 700 pistons...Now uses the 600 pin bearings that are wider (better choice for a 660 conversion on the 600)

Cylinders now use a 4 bolt exhaust flange, over the 3 bolt style
They have it running 23/39 gearing
64gm weights with a 66/44.46 helix for clutching

Just something to BS about while waiting for snow :beerchug:

where did u get this information from? I wonder why they'd cut the front rad i guess to save weight, I actually liked that feature because last year my rev would over heat on iced over trails while my riding buddys 900 switchback would be running ice cold it was one of the factors that made me make the switch i dont like this surprise at all.

Gonna have to find some loose snow every couple miles and pack the tunnel with it. My Firecat has the same problem running on the lake when there's no snow.

Polaris moved away from Elko as a piston vendor for the Dragon.

just doing some browsing, wanted to mention that the 600 CFI is using a 9 tooth tubular driver, like the other IQ's, except for the RMK's with the long pitch Series 5 tracks that use an 8 tooth driver.
