That is the Sundowner seat,the wide backrest with appropriate bar,sorry I don't remember the part #'s and have no clue where my catalog vanished to but it's all dealer parts.....my bud paid the $900+ for that package deal and when he traded off his 1200C to buy a Nightrain he gave me it FREE I hate the look but my ol' lady loves it,I call it the couch...
Does this seat raise you up, or about the same as stock 2 up?
I've never had the stock seat so I don't know. I was running the Mustang Vintage solo and it has keep me at about the same height but I get better footing since it is not as wide.
I have the HD reach solo seat on my bike, but when I ride 2-up I use a stock 2009 1200C seat as it looks and feels better than the stock 2-up seat that came on the XL50 package. The C seat leave a gap at the rear of the tank sicne it made for a 4.5 tank and I have the 3.3 tank.
