The tires also looked like a better trail design vs the xct that came on mine , aggressive deeper tread but closer together , my xct's only lasted about 600 miles before the rears were shot riding at HM . I deliberately rode both of ours on a decent little trail by my house 2 days before the trial . The trial was held at an off road park that has heavy sand and rocks (it was on silica sand rd) . I was able to make 2 laps in the 900S and the second lap I really tried to maximize the machine . I would let our leader get a little ahead of me and then really push it in corners and whoops , the 800S bottomed very quickly and hard in the whoop section and I had to let off , I stayed in it until I had to let off for a corner with the 900 and it did bottom but it was a gentle thud , not a teeth rattler. The power/suspension is matched pretty well and felt pretty nimble. Also we had 2+ inches of rain the previous day and I hit a couple deep water holes hard testing the waterproofing - it was , I wasn't ..
