I have the 2011 630TE. I never rode the 610. I am having problems with power, and I have to wonder if all these positive comments about the new 630 are Husky promoters, dealers, and not consumers who actually own the bike. I mean, one guy on here says the 630 is a power-beast once you do the power-up "kit." But the dealer in my area says there is no kit as such, but only the O2 sensor is removed and the fuel injection remapped. My fuel injection "remapping" SUCKS. The dealer is saying the
610 WAS a power rocket, but the 630 just is not. ????

All that displacement has to go somewhere, so re-re-map the FI, and I hope that after this Thursday I will be singing a different tune.
Oh, the seat seems to be fine, though. I have been doing 50 miles per day nonstop, and I feel nothing.
If anyone out there is also a 630 owner, please tell me the specs your FI was tuned to, so I can clue in my dealer. He wants me to try a smaller front sproket.... Trying to be happy, but running out of enthusiasm.
