I agree that the seat could be better and the accessories are a joke, especially considering the outrageous prices. HD accessories on the other hand are quite reasonable and usually far better engineered than the bikes themselves, but that is no reason to buy such a POS of a motorcycle.
I have only put 150 miles on my 06 Limited, but so far I have no complaints with the rear suspension. Overall I´m very impressed with the bike. I test rode a Roadliner just before riding the 2000 and I can say without a doubt that the 2000 is the better bike.
