First Ride on a Catalyst! | 2024 Arctic Cat Catalyst ZR RXC 600 | Super Impressive Snowmobile 

I rode 2 858's at the end of March in Gimli Mb. The first one was a Riot 858. The first and most noticeable thing was the engine vibration in the handlebars and the vibration at you feet. The Riot rode like a buckboard, it really kicked back on the bumps and it wouldn't turn at all. I know this possibly the setup. Also the gauge was a little square type probably off the atv line and it was terrible, could hardly see the display at 60 kph. I then jumped on a ZR 129 and it rode way better then the Riot and it would turn and handle great. The handlebar and foot vibration was same as the Riot. It had the new display and it looked and worked great. The vibration was concerning because after we got off you feet had a tingle from the vibration. I was not the only person on the test drive that commented on the engine vibration. The 858 pulled hard as it should. On a note there was 6 of us on the test drive and I was fifth, you could really smell raw unburnt fuel smell being in the rear. Possibly more mapping to be done on calibration.

Up to 60 mph, there is very little performance difference between a 600 class and an 800/850 class machine. North of 60 is where the bigger motors shine.

Nice sled

Stunning My first sled was a 1974 Harley Davidson 398! My last new sled was a 2 stroke Ski Doo MXZ-670 How far sleds have come! Great review!!

There must be something wrong with your 850 if you lost a race against a 600.
