Here is the final ratios for the 420AT, 500Foreman/Rubicon FM, and 500 DCT in both High and Low. I don't trust the numbers Honda gives for the DCT they just seem too low geared and it doesn't make sense to me. If I punch the numbers into a potential speed calc thing stupid thing should only do like 31mph at 7000rpm lol Compared to if I punch the the numbers for the FM into the same calculator it spits out 49.3MPH or 79.4KPH which is right about where I would expect it. (420AT says 49.0mph). So compared to the FM Foreman anyway, the 420AT is actually geared LOWER in 5th, but by less than 1%. The "potential" speeds are calculated on a 25" tire in 5th gear at 7000rpm, different tire sizes and actual engine RPM's will change that, as well as about 70 billion other factors....
500DCT L 23.85
500DCT H 16.57
