1. The rear suspension is really good. I mean really good! (I had ridden a '17 Assault this past spring at GunStock Ski Area but wasn't able to adjust the suspension due to lack of time) I ended up with the front skid shock at 2 clicks and the rear at 1 click. Front ski shocks ended up at 2 clicks. The field was rough in spots and had plenty of high speed whoops. The rear skid easily handles this terrain with ease. It feels very much like the R-Motion Doo skid but is a bit firmer.
This new IGX rear skid absolutely crushes my '16 Pro S LE with it's fancy shocks. I've owned 2 Rush style sleds and I'm telling you that neither of them ride as well as this new skid. Yes, the Rush can be set up to handle rough terrain or smooth trails, but not both. This new IGX skid is simply amazing. It's noticeably better right away. I've got a lot of time on the Doo R-Motion(had a 15 Renegade) and this new skid is very much like it.
2. Wow does this sled hook up! I have the Cobra with no studs. Just flat out hooks up. Weight transfer is great. Won't wheelie like the Rush skid but still holds the ski's in the air until about 50 MPH if you're hanging off the back such as in drag racing.
3. Engine starts easier and idles much better. Never saw my temp gauge get above 126 degrees. (outside temps were 25 degrees)
4. Clutching feels spot on. I was seeing 8100 at high speeds. Still in break in mode so I'm sure I'll see more RPMs once it's full broken in. Clutch engagement is around 3000 rpm. Shifts to 7900 then slowly climbs to 8100.
5. Power seems better in break in mode. I know from all the recent dyno posts that it's got a couple degrees of timing pulled out of it but it just feels better than my '16 did out of the box. Feels like top end is going to be much better than the Rush chassis. Rolling resistance is way less than my Rush.
6. It's hard to tell you're driving a sled with a 144" track. Just doesn't feel as long as it is. Very similar to the Doo Renegade in feel. The only time you notice the length is when it's hooking up! I know I wasn't driving on groomed trails but after driving these fields for a while, I was able to pack down a good amount of area and ride normally to just see how it would ride and handle.
7. Very stable at high speed. As I was approaching 98 mph, the sled held it's composure very well, even when the suspension was fully bottomed out on the whoop section.
Time will tell but I believe Polaris has nailed it with this new sled and IGX suspension. Everyone who has purchased an Assault will be happy the 1st time they get to pull the trigger on this animal. We know it goes based on the impromptu drag race against the '17 850 Doo at Gunstock last spring. Let it snow!
