That is pretty wild I had a stage 2 2017 Axys and I really thought it was head and shoulders better than my buddies who were on stock 2018 and 2020 Axys. Was it just that the platform was that good the power loss wasn't a big deal or was platform great and 600 fairly strong too?i have a 600 catalyst and ordered the 858. if there was no 858 i would ride the 600 with no problems. liked it better than my ascender and way better than the axis and g4 in our group. the axis was a stage 2 and then owner wants to buy my 600.
