When I rode them in Revy last Saturday I was impressed with the calibrations. Fuel and clutching seemed pretty spot on. No bogs or hesitations. Even the Riot 858 I tried was good, despite being told it was underperforming due to low elevation clutching. 1.6 146 track in spring snow didn't rob a whole lot of power. It was the most fun on the trail of course. Handled and rode great. Sno Pro with ATAC suspension needed work. Front felt like it had no give whatsoever and adjustments weren't working. Rear was ok. Was told they were still working on it. Others said the new 5 position shocks were good. Didn't get to try one with those.
