Everyone I've reached out to says that the 60t causes chain derailment after about an hour of riding. People lift them higher and do these things without really understanding the geometry of the whole thing and even if they do its not exactly a panel of scientists behind the installation of such modifications so its kind of a crap shoot at what actually works. From my experience on dirtbikes, I recall there being changes in sprockets by a few teeth here and there but a 14 tooth jump is kinda wacky. I wonder if a 54 is any better? It's a 19 inch tire, I'm probably in the 15 hp (max) range and smacking the torque out of converter no matter what till I get the Juggernaut on there. I dunno, they sell enough of those 60t for some reason.....
