Sundowner Seat is rated 1.5 out of 5 by 2.
Rated 1 out of 5 by from Nice back support but no comfort I was given a demo seat to try today which is awesome from a Harley to try before you buy. What a complete let down. The back support and angle you sit is great but what an uncomfortable seat. The worn stock seat is 100% more comfortable than the Sundowner. Great concept but not comfortable. It also is not 100% compatible with 2006-2000 bikes. Yes it fits but back hardware needs to be changed and missing side locking hardware.

Rated 2 out of 5 by from Not real leather I bought this seat hoping it would be more comfortable and be of the same quality as the factoy seat, but it wasn't. The only thing that is comfortable is the back rest. The bottom of the seat is hard and makes your butt get sore a hole lot faster than the original seat, now I'm going to have to pay to have some more padding added to it. I thought for as much as the seat cost that it would be real leather like the original seat was, but the only thing that is real leather is the valance on the sides of the seat. I should have bought a mustang seat, they are alot more comfortable and made of real leather. Overall I would not recommend this seat.

Seat Position

Does this seat position the rider back from standard? Looking to move back about 1 1/2" but the Tall Boy seat won't fit a Heritage Classic.
Asked by: kg5ie
Hi kg5ie, You will not notice any significant increase in reach. This seat is more so for a better support and it keeps you upright more. Thank you

does this seat lower short people closer to the road with a narrower inseam

Asked by: keith49
Well keith49, the Sundowner Deep Bucket seat is less wide than the stock seat by about an inch. So it'll get you a little closer to the ground. If you really want to feel more secure you need to look at the the Reach seats. They make a huge difference.
