Just picked up my Softail Slim 2 weeks ago. Very happy with everything this bike offers. It has the standard seat and I also added a standard type pillion seat along with a removable sissy bar mainly for my Wife and Daughters. I realise 1 size cannot fit all but I'm good for a maximum 45 mins in my seat and 30 mins is about it for all on the rear before its getting to uncomfortable. Any suggestions in regards to replacement seats or even having the originals re-upholstered with some extra cushioning would be helpful.

I have a similar problem with my Harley Davidson street Bob special. I'm good for 30 mins and then I get massive pain in myriads thigh which goes down to my calf. I'm pretty sure it's the seat and I just gotta sit up closer, get a sundowner or a reach seat.

I had a similar problem with my Cross Bones after an hour or so, fixed it by buying a Street Glide

Seriously though your dealer can lend you seats to try out for a day, go ask the spares dept. Sundowner seat is usually a good start, looks a bit gay though..

Thanks for the replies. Will contact HH Adelaide and see what sort of prices I'd be looking at. You've got to be comfortable. No wonder these bikes are so popular, They really are terrific to ride. P:S There is a company in the US, Mustang Seats, That seem to have the look and comfort with their wide studded touring solo and passenger seat to fit the Slim. Have to compare $$. Thanks again for replying!

A lot of these pains are probably stress related. When your doing something out of your comfort zone your muscles tense, even if you don't know it.  And just becuase you're enjoying it doesn't mean your body isn't tensing up.
I ride with a LePera Barebones, it's more than padded enough.

Thanks again to all for your advise. Taking it all on board.

Best most comfortable seat for Softails was/is the stock OEM seat that was fitted on the FXSTC Softail Custom 2007 to 2010

These fit right onto Nightrains/ Softail standards/ 2007/8 CVO Springers. ANY of the 200 rear bikes

Just fitted a copper insert 2008 FXSTC Anniversary seat to a mate's 2008 Anniversary coloured CVO Springer , twisted sissy bar and it looks great !

You do need a sissy bar , either the stock Softail custom one or one of the "twisted" sissy bars.

That's because they actually hold the seat onto the bike.

Will they fit a Softail Slim ? You'd have to measure up your bike , I have not yet worked on a Slim myself. All hinges on the width of the rear guard.

You may also be able to fit a stock OEM Softail standard seat , comfy but fugly

Thanks. Great forum to get advise on.

Had a Sundowner on the Sporty Custom, went around Nsw & Vic. Been around Oz in 2015, and around Nsw & Vic & Qld on my 2011 FXST. I have had Instrumental Spinal fusion in Aug 2014, and the Sundowner is deff worth the money.
